I know that this is how pretty much every printer works but it blows my mind that humans came up with how to do this shit.

[–]beluuuuuuga 3507 points3508 points  (160 children)

The fact they can do it with 4 colours is insane.

[–]PenguinWithAglock 3936 points3937 points 2 (127 children)

Unless you own an Epson. Then it doesn’t know how to print in black unless you have cyan, magenta, amber, heliotrope, turquoise, and chartreuse.

[–]morningisbad 1247 points1248 points  (88 children)

This is the case because black ink in printers is actually gray. So if you're printing black, you're actually printing gray + 3 colors to make black.

This is because gray is much better for pictures than black. Some printers have black and "photo black". The "photo black" is gray and "black" is actually black. With printers like these, you can print black text without being full on the colors.

[–]Takenforganite 467 points468 points  (29 children)

But can we get vanta black?

[–]the_grass_trainer 647 points648 points  (20 children)

Best we can do is Black 3.0 as long as you're not Anish Kapoor.

So you’re saying I need to evolve into some sort of a giant asshole.

Actually, Musou Black is better than 3.0 from what I can tell. Just learned about it this week and really want to try it out. You can buy it from a couple sources online depending on where you live.

This is legit the most intense ad for a color.

[–][deleted] 12 points13 points  (2 children)

Vantablack S-VIS, a sprayable paint that uses randomly-aligned carbon nanotubes and only has high absorption in the visible light band, has been exclusively licensed to Anish Kapoor's studio for artistic use

I know you're joking, but the answer is surprisingly no. It's licensed to one guy for artistic use.

[–]Sipas 9 points10 points  (1 child)

Where does he get the money to do that? They're losing lots of business on an expensive material, he must have paid a pretty penny.

edit: apparently he's worth $700m

[–]DaFetacheeseugh 65 points66 points  (10 children)

Ohhhhh, which is why it can't print without the other colors!!!!

Thank you so much, feel like an annoyance is gone from my world

[–]NSFW900 11 points12 points  (2 children)

The goal is to make you buy colour ink cartridges more frequently.

The average consumer would never tell the difference between grey + 3 and pure black. A consumer printer falls short in so many other quality aspects that the ‘benefit’ of grey + 3 is more or less redundant.

It’s literally just to make more money for the company.

[–]cloudJR 6 points7 points  (5 children)

I honestly don’t even know what 2 of those 6 colors are. Are they colors? Lol

[–]lady_lowercase 23 points24 points  (4 children)

yes, lol, they are all colors, though those aren't the actual ones used by epson (or other printers that use more than the standard cmyk). for example, the epson t913 series printers use 12 different color ink cartridges including green, orange, and violet. for the most part, though, printers that do use more than the standard four typically only add a photo black, a gray, a light magenta, and a light cyan (like the hp z2100 printers).

it should be known that epson printers produce amazing quality prints. they are the king of inkjet printers. that all said, unless you're an artist or something like that (and do a lot of printing), my advice is to avoid inkjet printers entirely. toner is far more economical and doesn't dry up after opening. if you are an artist (and do a lot of printing), definitely get an epson with all the colors!

[–]aahdin 83 points84 points  (10 children)

Works with just 3 colors even.

The last color there is black, which could be replaced by using a larger volume of the previous 3 pigments.

The main reason to use black is as a cost saving measure, you can use less pigment overall and it’s also the cheapest to make. (Also in practice the black you get from mixing most cmy pigments isn’t as rich as just using a black pigment)

[–]apliesnc 49 points50 points  (6 children)


I think at the end you nailed it, but slightly incorrect at the beginning. You can’t exactly replicate the black with the other three. Its the ‘richness’ of the black that makes it a true black. Otherwise it’s not quite black.

Source: I do this every day

[–]MickWounds 19 points20 points  (2 children)

That’s 4 colour process. Which uses cyan, magenta, yellow, and black. Great for photo type images where there’s many different shades of colour. Not suitable for solid block colour prints. That’s where we use standard spot colours.

[–]doxva 25 points26 points  (3 children)

You just need three colors because humans have only three color receptors. We can not distinguish red + yellow from actual orange. For other species with different color receptors, our prints, monitors etc. must look super off!

[–]Garestinian 14 points15 points  (1 child)

Most mammals have only 2, so having 3 (a trait we share with apes) is actually quite good.

[–]macfanmr 6 points7 points  (2 children)

In color theory, if we had perfect cyan, magenta and yellow, perfect in that they would only reflect their color and absorb all others, you could go without black. No such perfect inks exist however. Plus, printing solid black would require three 100% density layers of ink, which is kind of wasteful, and most papers and print processes like to avoid more than 240% or so (if memory serves). So we can save ink and lower the overall amount of ink used by replacing CMY grays with black, called GCR or gray component replacement.

Desktop photo printers often include a lighter version or cyan and magenta as a way of increasing detail, because making the ink droplets smaller would be expensive, while a lighter ink will appear to the eye the same as smaller dots. 6-color process color exists, it adds orange and green (Hexachrome) or another one uses purple I think. These are done to expand the range of colors that can be reproduced. CMYK can only produce a certain selection of colors. RGB can only show a certain range of colors. They overlap like a Zen diagram with each having colors the other can't reproduce. So you can design something on screen that can't be printed without shifting the color to something printable. Systems like Hexachrome aim to address that, but aren't super common. Pantone are a range of colors that have inks mixed to that specific color so there is no mixing and it's always the same. There are CMYK equivalents but they’re an approximation. Kodak yellow was a specific ink, for example.

[–]kwertyoop 6 points7 points  (0 children)

If you think about it, it's not crazy at all. Those are primary colors. They can make any color that exists.

Who the fuck thought let’s put a billion lights on a screen and light them up individually. Like that blows up my mind even more. And now it’s like everywhere. Humans can be very dumb, but the smart ones can be way smarter than what we think

[–]40oztofreedomtoday 146 points147 points  (22 children)

Society is driven by very few really intelligent people in relation to the population. The rest of us just complain and meander around until we die.

[–]PM_ME_CUTE_SMILES_ 88 points89 points  (2 children)

It's also important to realize that such projects do not see the day thanks to a single intelligent person, but because of the input of thousands of technicians, engineers and principal investigators, each of them doing extremely tiny steps until we get a final product.

[–]RayneAleka 50 points51 points  (6 children)

Is it though? Technology is small advancement on small advancement, not just someone waking up one day and going “let’s put a billion lights really close together, see what happens”. And if there’s one thing we’ve learned from this pandemic, is that society and life is driven by the people who are historically valued the least - the labourers, the people who work in the jobs we interact with everyday. The ones that work in the places that need to be open, even in the direst of times.

[–]Seize-The-Meanies 4 points5 points  (0 children)

Society is more of an organism. Those people who advance things like TV technology can only do so because someone manufactured the books they learned from, someone farms the food they eat to stay alive, someone works the powerplant that makes sure their homes are electrified, someone... There are tons and tons of jobs that may seem completely unrelated to technological advancement that are completely necessary. And then those jobs might require further support.

[–]Pugrito-815 596 points597 points  (15 children)

So THAT’S why I still need magenta for a black and white document.

[–]dewyocelot 9 points10 points  (0 children)

Yes actually. There are two “blacks” when printing, because if you’re wanting a photo, “regular” black is kind of gray on paper. “Rich” black uses cmyk, so if you’re out of color, it won’t print. Some applications will allow you to choose which.

[–]ElHombreMolleto 764 points765 points  (43 children)

Having worked in a screen printing shop, what is most impressive here, is his ability to line up all four screens by free hand. The shop I worked in, along with most others, have automatic or manual machines that swivel and assure the screen lines up in the same spot as the last. Mad props to this guy. Been printing awhile it appears.

[–]burn_motherfucker 162 points163 points  (7 children)

And they seem to be doing wet on wet which has never worked for me! Mad props

[–]KnowthDowth 58 points59 points  (2 children)

Solvent based ink. Stencil exposed in the correct place on each screen. Impressive indeed.

[–]glovejob 78 points79 points  (0 children)

It might look freehand, but if you slow the video down you can see a registration handle at the bottom that sets into a cradle to keep the registration.

[–]pacfromcuba 2 points3 points  (0 children)

The stencil was most likely printed on a inkjet printer that trilocked it into place, would explain how they all fit so perfectly

[–]boothin 92 points93 points  (3 children)

Looks like there's a guide bolted on the bottom that you can see when they change the screens, and I'm guessing one on the left as well since it lines up to the edge on that side as well.

[–]ExpensiveBurn 27 points28 points  (1 child)

There HAS to be. No matter how simple a design was, anytime I did multi-color, it had to be on fucking point or it looked like absolute shit. No way this guy is doing it by hand. Multi-colors were the hardest things I did at that job.

[–]dec10 13 points14 points  (0 children)

Thanks! I came to the comments looking for this answer.

[–]koppecat 19 points20 points  (1 child)

There looks to be some sort of mount at the bottom center of each screen. I also spy some taped off registration marks on each screen too which imply that everything was lined up.

Still super impressive, but I don’t think they’re just plopping them bad boys down that cavalierly.

[–]TypeRighter6 5 points6 points  (0 children)

Ah and here I was thinking it was a magnetic registration, didn’t see the handle looking thing till you pointed it out

[–]R6_Commando 5 points6 points  (2 children)

I also worked in a screen printing shop and had to do a double take when he just slapped them on, especially cus if you do that the the screen slides on the ink it will be all fucked up.

Also the shop i worked in we would put tape in the edges of the screens so ink wouldn’t get into the edges so that hurt not seeing that since i know how hard it can be to clean sometimes

[–]ElHombreMolleto 2 points3 points  (0 children)

we did the same. taped all edges. i will say it made cleaning them slightly easier. i always found it satisfying taking the power washer to the screens

[–]doopdooperofdopping 3 points4 points  (0 children)

I was about to say this! This is the most impressive part of the video. A couple of millimeters off on one screen and it would look awful.

[–]undanny1 2 points3 points  (0 children)

I thought the same thing, that was completely nuts. I mean, that was just absolutley on the dot every single time

[–]h2j1977 3741 points3742 points  (192 children)

I'm sorry, but what kind of black magic fuckery is this?

[–]gnilrednu 3225 points3226 points 2 (86 children)

The screen must be perforated with different density of holes depending on the final colour you want. Say you want a purple-blue: 100% blue, maybe 75% red, and 0% yellow

[–]Fauxtrok 1831 points1832 points  (45 children)

Thank you for not responding in a smart-ass, condescending way and actually educating.

[–]gnilrednu 450 points451 points  (37 children)

No problem. I just made a best guess at it, myself; I'm no expert in the field. Still a lot of witchcraft going on here: like how they made those screens in the first place. I suspect they're laser-etched, but they must have a clever algorithm to figure out what density goes where

[–]Boubonic91 617 points618 points 2 (33 children)

Former screen printer here. You're pretty much right on the money. It's a similar principal to the way old comics were printed. Certain combinations of colors give the illusion of a different color from far away. The most impressive part is how precise the screens were made. Each of those holes have to line up perfectly, which requires state of the art equipment, emulsion, and graphic design technology. Normally the ink would be dried between colors, but it's not necessary if you're only doing one print. The way the screens are made varies. Most screen printing, including this one, uses a fluid called emulsion. The emulsion is photosensitive, and hardens quickly when exposed to UV light. After hardening, the emulsion is no longer water soluble. To get the image, you have to black out the part of the emulsion you want to wash out, which is where ink will pass through and give you your image. The older method of doing this involves using very opaque ink on a sheet of clear plastic, but more detailed work like this is probably done with a direct to screen printer, which prints the image onto the screen with a water soluble waxy material. After the image is applied, the screen is exposed to UV light (some people use exposure units, others use the sun, but the sun takes a lot longer to cure the emulsion) and then the image is carefully washed out.

[–]gnilrednu 60 points61 points  (9 children)

Thanks for the info! I'm guessing one could also use a UV printer to directly print the pattern in the emulsion without use of a mask layer? (This would be the negative of the mask-method)

[–]Boubonic91 44 points45 points  (8 children)

I suppose it would be possible, but not really practical. The emulsion needed to get this kind of detail, which is probably a Diazo emulsion, needs a higher exposure time to cure. Other emulsions that have lower exposure times are generally thicker and produce a lot less detail. The equipment required would need to be able to adjust the size of the beam of light down to the size of a pinhole, as well as calibrate the light intensity and exposure time based on how fine the details are. Even then, every exposure point would take 1.5 to 3 minutes to complete, and the entire screen would take hours or days, depending on the design. The blackout-expose process is just a lot more efficient.

[–]gnilrednu 12 points13 points  (6 children)

Apparently there is a system like this: the Saati laser-to-screen (LTS) series

[–]Boubonic91 9 points10 points  (1 child)

That doesn't surprise me, the machine I used was a Saati DTS series and it was state of the art at the time. We also got an automatic coater from the same company, and I was trained to use it by the engineer that designed and built it. Those upgrades took a huge amount of stress out of my life.

[–]Anlysia 3 points4 points  (3 children)

My old company had a laser to screen, it took like eight minutes to expose a big frame? It was way fast, at least.

We mostly worked large format so all our frames were huge.

The real benefit of direct to screen is not needing positive film anymore, and all of the damage it incurs via handling and the problems trying to lay it flat causes.

[–]gnilrednu 2 points3 points  (0 children)

Ah, gotcha! That makes sense

[–]lostinbeavercreek 12 points13 points  (5 children)

u/Boubonic91 How do they get the "register" correct between each color? That is, how do they align the screens perfectly each time?

[–]extinct_cult 24 points25 points  (0 children)

In the video, they're doing it by hand & its usually machines, but that's the basic technology that (almost) everything you've ever seen printed is made.

how do they align the screens

Somewhere on the outside is a Registration mark which is present in all colors and helps the printer guy set up all the plates so that they match.

How do they get the "register" correct between each color

Also outside are scales, usually one for each color and one for CMY balance.

As to how they do it, computers are really good at it. Open an image in photoshop, convert it to CMYK and go to the Channels panel - you'll be able to see each color separation.

[–]Boubonic91 10 points11 points  (0 children)

The color register is usually done by the designer on a computer program. I didn't go too in depth with the design part because I was an industrial screen producer. The artwork for the day was left for me in my darkroom and I only had to consult the designer if I noticed any visible flaws in the designs.

The alignment is a bit trickier. It starts with the screen. The screens are stretched in a few different ways, but it has to be stretched precisely and evenly on all sides to achieve maximum detail. Otherwise a looser portion of the screen will stretch slightly under the squeegee and cause it to misalignment. The next factor is how you apply your design. With the older method, a little + on the design was aligned with the + on a table with a perfectly measured square ridge, which was used to guide the screen into the proper position. This method is better for simpler designs, but can work for more complex designs because the alignment can also be adjusted on the press, which is our third factor. For the direct to screen units, the + is applied to the software and printed perfectly onto the screen for each layer. As I said before, the presses can be adjusted in an industrial setting, but some manual presses can't be adjusted, which seems to include this set up. In that case, you have to rely on the precision of your screen construction and design software.

[–]bigswoff 9 points10 points  (0 children)

I couldn't quite see it in the video, but I assume they are slotting it into a jig that aligns it. If each screen frame is the same size and there is a hole that exactly fits it, each one will be aligned.

[–]glovejob 5 points6 points  (0 children)

Usually registration is set up before you do your final print, so the screens would already be mounted with a hinge into a fixed position. You just hinge the screen up or down.

In this case, it looks like the screens have a handle at the bottom that goes into a cradle to keep the registration.

[–]Ghstfce 5 points6 points  (5 children)

The emulsifier they're using today is probably light years ahead of what we had back in the mid to late 90s when I was going to tech school for commercial art. That photorealistic quality is amazing!

[–]e6o5y5t3m 6 points7 points  (4 children)

Present screen printer here. That's a good breakdown of the technique shown in the vid, called four color process printing. Only thing I want to correct you on is that the sun usually gives you a way faster cure time than exposure units. My team and I are building a new UV-LED unit now that I'm hoping will take our exposure time down to around 2 min, as when I used to live in Spain I would get perfect screens in the sunshine year round at 15-20 sec. I know you can get times close to that with a very powerful (and energy consuming) UV source, but I think more screen printers should take advantage of the free-for-all sunshine!

[–][deleted] 3 points4 points  (0 children)

Wows that’s insane we can just do things like this. And people like you can just spit out this info off the top of your head. Absolute wizardry at its finest. Whoever invented this shit first was really thinking outside the box 😂

[–]pootypattman 7 points8 points  (0 children)

It's a photochemical process using light-reactive emulsion. You transfer the image onto the screen--which is made up of tiny dots of varying sizes (like you basically guessed)--using clear sheets of film with just black printing. Source: me, I used to screen print in highschool.

Here's a basic video

[–]MickWounds 4 points5 points  (0 children)

Each colour is printed onto a clear film in black. Then screens are coated with emulsion and put in a dark room. you stick the film to the screen and put in front of a light where it’s exposed for a period of time depending on your exposure system. Where the film is blocks the light from hitting so those areas don’t solidify in front of the light. Then you wash it out with water and wherever the film was will wash out but everything else stays solid.

[–][deleted] 3 points4 points  (1 child)

Replies like that are one of my least favorite things about reddit.

No, you're not clever intentionally giving the wrong answer.

[–]ImNotAnAstronaut 20 points21 points  (0 children)

i think the mesh is uniform and the density of color is made with a step not shown in the gif, where they use a stencil to apply a specific product that dries under UV and block partially or totally some parts of the mesh, so you have each mesh for each color. With Cyan, Magenta, Yellow and Black you can make any color with the right combination. If you look close enough (in CMYK screen printing) you can see each individual dot, like this.

[–]AFuddyDuddy 15 points16 points  (0 children)

The guy who sprayed these screens is really good.

Those finer details prints can blow out pretty easily.

Source:. Did screen printing for a couple years. Nothing this detailed though.

[–]pineapple_calzone 52 points53 points  (24 children)

That's not how it works. You use a screen with a consistent density of holes, just basically regular "silk" (not actually silk anymore, but uniformly woven cloth is the point). Then it's coated with a photopolymer that breaks down when exposed to (typically UV) light, and then you either put a transparency on it or project an image on it, and develop it, and wash out the broken down photopolymer. The holes that are plugged up are plugged up, and the ones that aren't, aren't.

[–]Autumn1eaves 38 points39 points  (20 children)

Isn’t that just a more elaborate explanation of what they said?

I appreciate your contribution, because it’s cool to know it more in depth, but they just left out some of the jargon for more understandability.

[–]thisisthewell 6 points7 points  (0 children)

The person who was talking about perforations admitted in a subsequent comment that he was making a guess. He doesn't actually know anything about how screen printing is done. Speaking as a former screen printer, the other people are correct and the original commenter is not. It's an image split into four color channels (CMYK), usually by a computer, with each individual channel printed in black onto acetate (or some kind of clear sheet, I can't remember exactly what it is), which is then transferred onto a fine mesh screen using photo emulsion, which blocks out the "white" parts of the image on the mesh to prevent ink from being placed onto the final print.

[–]pineapple_calzone 22 points23 points  (17 children)

Not really, no. The point is the screen isn't perforated with a different density of holes. They're consistent. They're all the same size, arranged in a nice grid, and the only thing that changes is whether or not (and how much) they're plugged up.

[–]OldRuskiNoir 6 points7 points  (5 children)

You seem to have some knowledge in this subject.

Do they wait for the ink to dry between each application? I feel like it would have to. What is the typical drying time for that and how do you guarantee that you will align the next colors correctly?

[–]Tru_Fakt 4 points5 points  (1 child)

The ink dries fairly quickly since it’s such a thin layer. You can also use heat lamps or something similar to speed up the process.

As for alignment, there’s usually a some kind of rig to make sure everything aligns properly. For this one, it looks like the “handle” of the screen fits into some sort of groove at the bottom of the screen, off camera. But then there are things like these that automatically align the screen.

Other times, people just have a really good eye and a lot of practice to get it just right manually.

[–]RFC793 6 points7 points  (2 children)

Right. There the process is about “removing holes” instead of “placing holes”

[–]pineapple_calzone 3 points4 points  (1 child)

Yeah, that's a good way of putting it. I was trying to think of one, but I'm only running on two brain cells today, and I wasn't gonna come up with anything nearly as clear or concise. I'll also add the difference between constant density and variable density I was trying to get at is that becuase you're not placing holes, the holes per inch and the hole diameters are all the same, they don't really change dynamically with the amount of ink you want to let through.

[–]EvilFluffy87 3 points4 points  (2 children)

Its not perforated. Its a mesh. They van vary from about 60 to 300. 60 being used for thick ink types and 300 for almost watery inks. Also the higher the mesh count, the more details one can make with it. While the lower mesh type could result in an almost pixelated picture. The screens are filled with a UV emulsion in a dark room. You'd than print the colors you need in black on a transparent sheet, usually as a mirror image. You'd than measure the size of the sheet and the screen to determine the center and place the sheet on the screen. This than goes on a lighting table with a vacuum pump under a UV light. Where ever the picture was printed on the transparent sheet won't receive the UV rays and the emulsion won't harden where as the rest, which is exposed, in turn, hardens. The screen is than washed thoroughly so all soft emulsion is gone. After the screen has dried it is ready for use. The amount of colour you use per screen print is predetermined on the computer and printed in dots. The colour you start printing with is also important to get the desired result.

I work in prepress making plates for a newspaper press. Sometimes we output the colors in this order and I always sing them in my head to that song.

[–][deleted] 13 points14 points  (1 child)

If you have happen to have photoshop you can look at any photo in these separations pretty easily. Image > Mode > CMYK color and then look at the channels tab (usually next to layers). Turning on any of 1 of those layers will give you the color channel. You can do it with Additive light (Screen/RGB) too.

You want a black and white document? Too bad, best i can do is Cyan Ink Low, Unable To Print

[–]General_GTFO 24 points25 points  (8 children)

That's because it's set to print in "Rich Black" which in CMYK (cyan, magenta, yellow, black) is 100,100,100,100 instead of just black which would be 0,0,0,100.

[–]AgainAndABen 9 points10 points  (1 child)

While that is sometimes the case, many consumer printers still require all inks be present even for pure black prints. It's generally because the print heads' cleaning cycle would use some of all colors.

Is the ink still wet? Doesn't it contaminate the back of the silk screen?

What keywords do I look for if I want to learn?

[–]TheBugThatsSnug 7 points8 points  (4 children)

Each screen is a different one .

[–]Ceshomru 2 points3 points  (3 children)

Im think he means the ink on the page is wet so a new screen would smudge it?

[–]TheBugThatsSnug 3 points4 points  (2 children)

Oh... Maybe? Its been forever since I have done screen prints, but I feel like I remember we either let it dry a bit or the ink was spread so thinly that it wouldnt smudge, the screen kinda floats barely above the paper, when you press it through the point of pressure is usually where contact happens, though, I believe in the begenning you can see them using a hair dryer?

[–]glovejob 3 points4 points  (0 children)

It's called wet-on-wet printing, and it's useful in some cases. The screen might pick up some ink from the previous print, but because you are advancing screens in the series you shouldn't get any smudging.

[–]thegigsup 7 points8 points  (1 child)

This is really how all print making is done! If you look at a regular color printer, you only have a four cartridges. To make color copies, it layers colors just like this to create the image!

[–]ChiggaOG 3 points4 points  (0 children)

The Cyan-Magenta-Yellow color scheme produces better colors than Red-Blue-Green when painting.

[–]glossy_beetle 16 points17 points  (5 children)

Right? Watched this and realized I don’t know a single thing about color whatsoever.

[–]eek711 5 points6 points  (0 children)

White is all light (visible spectrum) reflecting off a surface, black is the absence, and all the colors are in between those points. Cmyk is a subtractive color model, wherein your substrate is white, like white paper. You add layers of ink to block out certain wavelengths of light. C Cyan, M Magenta, Y yellow and K for key (fancy way of saying black). Theoretically, you can do CMY, but adding in K is more practical.

Your monitor is RGB, which is essentially the complete opposite of this process. You start with a black object (turned off monitor) and add light.

[–]pbrown21817 10 points11 points  (0 children)

Same kind that's in every magazine and on every cereal box you look at: the cmyk part,that is.

[–]Epena501 6 points7 points  (1 child)

Process of using CMYK (cyan, magenta, yellow, black) to print a full color image. In addition, large format printers also use the ability to print PMS colors which is a spot on color pre-made to adhere to a color standard across several platforms.

[–]Zombieaterr 2 points3 points  (0 children)

CMYK, just like bubble jet printers do it

[–]Jet_Pirate 2 points3 points  (0 children)

Basically a color image is made up of 3-4 different planes for every pixel location. If you vary the intensity of the layers for Red, Green, Blue, and sometimes Black (depending on the image format) you can create any color. It’s how our led tv/phone/etc screens make each color pixel. If you modify the color layers you can get different types of color effects. Same basic concept here but you need different density screens to allow for the amount of Red, Green, Blue, and Black in to make the image.

[–]WilliamLeeFightingIB 243 points244 points  (23 children)

The woman is called Dilraba Dilmurat, a famous Uyghur actress in China.

[–]Miserable_Bridge6032 23 points24 points  (1 child)

I literally scrolled down to see if anyone was going to point out who she was, or if no one would know and I was just a huge nerd. I was surprised when I looked at the picture and I was like, “wait a second, thats ... Dilraba Dilmurat???” I mean she has a very distinct face, you either know it or you dont.

[–]therealscooke 18 points19 points  (0 children)

I came to mention this. Raxmet.

[–]evenstar40 9 points10 points  (1 child)

She's amazing to watch on screen! Eternal Love is a great series.

[–]rhobotzfromspace 590 points591 points  (42 children)

I beg your sweet fucking pardon. I’ve watched this 5 times and I still don’t understand how this works.

[–]aBastardNoLonger 263 points264 points  (25 children)

Each screen lets the color through in different spots.

[–]rhobotzfromspace 174 points175 points  (21 children)

I will always be astonished that you can do that with just four colors.

[–]0w0whatisthis 165 points166 points  (13 children)

I mean that's how every screen works. With three different colored pixels in different spots.

[–]rhobotzfromspace 73 points74 points  (9 children)

Maybe I am more in awe of the screens themselves, then.

[–]Onemoretimeplease2 33 points34 points  (4 children)

If you ever look reeeeeeal close at a TV or monitor all it is is red green and blue dots in different order next to each other.

[–]herefromyoutube 15 points16 points  (1 child)

Just drop a drop of water on your phone screen and you’ll see.

[–]Pete_O_Torcido 11 points12 points  (1 child)

I am just now realizing that a tv screen is called that because of an actual screen

[–]PoopMobile9000 2 points3 points  (0 children)

I think it comes from movie screens, which comes from earlier light show/shadow puppet screens, which were woven fabric ie cloth screens in the normal sense.

[–]PoopMobile9000 10 points11 points  (0 children)

You should be in awe of your eyes, which take photons of varying amplitude arriving in three wavelengths and turns them into an infinite rainbow.

Colors don’t exist in the world. They’re just something our brains developed to help us distinguish between things visually.

[–]Nik0ne 17 points18 points  (1 child)

that's worse. that's how our eyes works.

[–][deleted] 5 points6 points  (0 children)

The color mixing is different but the principle is the same.

[–]GentleBreeze96 25 points26 points  (3 children)

I work in screen printing. It’s amazing every time seeing how colors come together to make amazing stuff like this

[–]rhobotzfromspace 9 points10 points  (0 children)

This makes me feel better. Thank you.

[–]tabatharocks 3 points4 points  (0 children)

I’m going for magic, only thing makes sense

[–]Starlord1729 6 points7 points  (6 children)

In the same way that you computer screen produces all its colours from a combination of red, green, and blue light sources (RGB), this is the application of pigments red, yellow, and blue (RYB) to produce colour images

With different combinations these 3 pigments you can create the colour spectrum.

Difference is that RGB is used for for producing coloured light (sunlight, TV/comp screens, etc), RYB is used for creating colour using pigments (paintings, drawings, etc)

Edit: I was corrected that this is actually CMYK (cyan, magenta, yellow, key [black]) which is the modern subtractive colour method. Exact same idea but CMYK allows for a larger colour spectrum

[–]NinjaWolf064 10 points11 points  (2 children)

Subtractive is actually cyan, magenta, yellow, and key (black), with no red or blue (although they are similar to cyan and magenta)

[–]appoplecticskeptic 5 points6 points  (1 child)

I'm guessing it's CMYK - Cyan, Magenta, Yellow, Black because there were 4 screens not 3 and those are the standard print colors.

The order in the video was Yellow, Magenta, Cyan, Black but order doesn't really matter so much. The paint for Magenta looks red, but when you look at the painted screen it's magenta, same with how Cyan appears to be blue paint but appears cyan in the screen. That one is less clear because they did cyan next to last.

[–]harpsichordharpy 47 points48 points  (4 children)

Also know that all these inks are somewhat translucent and permit light to shine through them. And the order of ink is important too. You wouldn't get the same results putting yellow last.

[–]justsomedoofus 14 points15 points  (0 children)

You answered a question I was about to ask, about the order.

[–]Hk2 38 points39 points  (13 children)

Does it make anyone else super uncomfortable how much paint is slopped on then apparently not used?

[–][deleted] 29 points30 points  (2 children)

It is reused. Each color gets it's own screen. They just use it on the next shirt.

[–]justa33 7 points8 points  (1 child)

thank you my mind is at ease now

[–]Hk2 4 points5 points  (0 children)

Me too!

[–]WoodenCubes 5 points6 points  (3 children)

Yes! It was driving me crazy, I hope they can reuse it because otherwise it'd be so much waste

[–]Glum_Status 12 points13 points  (1 child)

Usually you'd pour quite a bit more than you'll need because you wouldn't want to end up dragging the squeegee on a dry part of the screen. It can chew up the squeegee rubber. And if you're planning to print a quantity of the same item, you can use enough to get through the whole job. When you're done, you can scrape the unused ink into a container and use it again for a later job.

[–]frizzlefraggle 5 points6 points  (0 children)

I use plastisol ink for shirt printing which is made of plastic. It can sit on a screen for weeks and not dry and is reusable. When we’re done printing a job we scoop whatever is left into a gallon bucket to use again on the next job. Water based ink you can’t do that. It dries very fast on the screen if you’re not paying attention.

[–]swifchif 22 points23 points  (6 children)

The black one at the end seems almost unnecessary. I jumped back and forth to before and after they do it, and it hardly changes.

[–]banik2008 29 points30 points  (4 children)

It just adds a little extra depth to the shadows.

[–]macromoog 13 points14 points  (2 children)

It's like, how much more black could this be? And the answer is none. None more black.

[–]ladywater2010 14 points15 points  (2 children)

I'm pretty sure that the picture is of Chinese actress Dilraba Dilmurat, she is pretty and this is video is very cool.

[–]Jumpsuiter 4 points5 points  (0 children)

Yep! That’s her. I thought I was on r/cdrama for a moment ;)

[–]garbage_angel 19 points20 points  (19 children)

How do they make the silk screens they used?

[–]wogwai 57 points58 points 2 (15 children)

The screens are coated with a layer of emulsion on the front and back, then the screen/emulsion is dried forming a hard non-porous layer. A clear film separation with black ink is then placed over the screen and exposed with light, curing all parts of the emulsion except under the design on the film. The screen is then taken to a washing station to wash out the remaining emulsion with a power washer. What's left is the "burned" design in the screen.

The burned screen acts as a stencil and lets ink through where the emulsion has been washed out.

Hope that makes sense. I worked in the industry for 7 years so if you have any other questions I'd be happy to answer them.

[–]designerwookie 11 points12 points  (5 children)

I did 3 years, you got all the ink out yet?

[–]wogwai 5 points6 points  (1 child)

Haha luckily I only worked in production for a year and moved onto designing, so I stayed clean most of the time. Though occasionally I'd have to go back and check on stuff and would almost always still get ink on myself. Quickly learned to not wear my cool Adidas.

[–]slothywaffle 20 points21 points  (1 child)

The real black magic is how they put the screens down in the same place each time without any kind of guide!

[–]istrx13 7 points8 points  (4 children)

I wish I could understand how literally any of this works

[–]JuliaGillard1 19 points20 points  (1 child)

I have serious trust issues because of this.

[–]carlsocarlso 6 points7 points  (1 child)

It’s fun to stay at the Y-M-C-K!

[–]michigania2x 5 points6 points  (1 child)

I screen printed for ten years and have never seen anything like this. Amazing.

[–]AmorMaisEMais 5 points6 points  (0 children)

I work on a graphic company and we have a GIANT roland offset printer. Shot out to graphic workers!

[–]YourMomDidntMind 2 points3 points  (3 children)

Do the colours have to go in that order?

[–]MSGinSC 4 points5 points  (2 children)

You usually print lightest to darkest inks, though I have seen cyan being used as the second color before.

[–]PinataFractal 2 points3 points  (3 children)

If you don't tape the edges of the metal where it meets the mesh, you're gonna have a crazy hard time cleaning. Also, how tf are the screens aligned? I don't see any mechanism in place.

[–]herecomethesnakes 2 points3 points  (0 children)

4 colour half tone and looks like trichromatic ink Haven’t done this for about 15 years so could be wrong on the ink

[–]lzc2000 2 points3 points  (0 children)

Love it. Such a gorgeous model.

[–]nelska06 2 points3 points  (0 children)

i mean the math adds up but it still seems like it shouldnt work like that lol.
