Hey /gd lurker hear.

I'm a web designer so I use RGB. Just got a job from a friend whose print designer has let him down. He called me an hour ago for a favour and the deadline is tomorrow so I'm making labels. Why is it that all the cmyk colours are so dull and yet I see vibrant colours in print all the time? Even the illustrator file of the old labels have good bright colours yet when I use them in my my one they dull up. Please help me /gd/

I havn't printed anything yet. Just staring dully at those dull colours on my screen hoping to get some advice.

your screen isn't calibrated right. And usually cmyk colors look worse on a screen than rgb colors because they are meant for printing.

do they look good when printed even if they look dull on the screen?

How bad is your screen that it would warrant a thread like this? How dull is actually dull?

Your colors are named so you get an idea what they'd actually look like. If you care this much just get a physical color guide. Make sure you're using the colors appropriate for uncoated or coated material.

That's because you can't represent a lot of cmyk on screen. If you want to really do it right you contact the printer and get some color samples, or go in and decide which color you want and they'll give you the values.

What's your monitor?

Pretty sure everyone who has replied has no idea what they are talking about. CMYK is more dull since paper doesn't have a built in back light to allow vibrancy like your monitor does. That said, once it prints out it can be slightly more vibrant if you use nice or coated paper. There are some colors that most printers just cant produce and CMYK helps reduce the chances of you hitting these colors. Advanced commercial presses can hit a lot more colors that CMYK mode restricts but it's better to not take your chances unless you get a color swatch for the exact model you will be printing on. I run a print shop and can tell you CMYK documents do look better on paper, and print much nicer than RGB docs do.

It can be a nightmare sometimes, but the only way to assure that the color looks right is to print it (and in the same process that you'll print the finish material).

It's never ever like you see it on screen.

Thanks for the help. I guess I'll just print off samples as I go along

Holy crap, how much shit can you make up in one post?
Please refrain from talking about what you clearly don't have a clue.
RBG works in an "additive" mode, meaning that the more color you add, the closer to white the result is. CMYK is the other way around, the more you add, the darker, because it's "subtractive".

CMYK isn't some thing "created" to reduce the chance of hitting some colours". Cmyk is just how physical paint works.

That being said, CMYK will always look a bit dull on a screen because your screen is converting the 4 colours from print wich work in a subtractive way, to just RGB wich works in a completely different way.
Advanced presses use the same CMYK as your home, they just have better inks and use higher quality paper, so thinks will obviously look nicer.

Overall, that being said, your best bet is to print some samples along the way. If you really want the best results, go somewhere that can print you a proof.

I prefer HSL. But you definitely want to do that shit CMYK if it's gonna be print.

There are presses with more than 4 colours man, they don't just 'have better inks and paper'.

Presses with more than 4 colors are rare— the most complicated of which is the Digital Hexachrome 6C with light CMYK overprint on a second run.

>Double-run overprinting from two different devices almost never matches up.

Not to mention, the quality of hexachrome prints depends heavily on the thickness of the cardstock, its ability to absorb ink (fiber quality) to prevent bleeding and the paper brightness itself.

There's a handful of companies that make paper brighter than 100 "white" usually using composites and or titanium dioxide/aluminum oxide.

Now, some printers will use white underprinting to create a masking layer ontop of non-white, clear or even white paper. Some will even use a metallic ink or pearl white ink to make colors really pop.

However, if you're using pure spot color inks from pantone swatches, you're limited on the available amounts of color blending you can do. Also, you're almost entirely limited to offset printing.


When using the CMYK spectrum, you have to have knowledge of how the values on your screen represent values in real like.

AKA Brilliant Red is not C0M100Y100K0...

Brilliant Red is closer to C0M100Y85K10.

Inkjet/bubble jet printing is the absolute worse because you can't get the true saturation levels needed for AMAZING color.


DPI. Good color coverage requires a DPI of 600+.

Your only option for reliable, fantastic printing on cheap office depot paper is to print everything with laser.

Holy motherfucking shit.
CMYK stands for Cyan Magenta Yellow Black. All CMYK colors are made with a mixture of those 4 colors. This is a subtractive process, just like Anon mentioned above. Offset press typically run those 4 colors.

CMYK colors look dull because they ARE dull, especially relative to RGB. The RGB (red, green, blue) color gamut is much bigger than CMYK.

OP, also I'm sure your color profiles are playing a part in your issues. Once a file is converted to a certain color profile - lets say SWOP, the color information is lost forever. So if you have file using Adobe RGB color profile (remember RGB has a wider color gamut) and you convert that to a SWOP color profile (which is CMYK, smaller color gamut) you've lost that original color information.

So, cmyk is dull because that's the nature of it. Most of the really bright printed colors you see are SPOT colors. These are special inks that create colors that cannot be created with a mixture of CMYK inks.

Some digital printers do a better job of hitting a wider color gamut than CMYK allows because some use as many as 12 different inks. The regular CMYK inks plus, a 'light Cyan, light Magenta, Green, Orange, etc.

The digital printer companies make their high end prints (like Epson's Pro series) with 8 or more inks BECAUSE of the limitations of using only CMYK inks.

On a more practical note, you should do all your designing in RGB mode and only switch to CMYK at the very very end.

Subtractive full color E-Ink monitors when?

CMYK=for printing RGB= for "web online resources", just use CMYK ull get used to it, and yes they will look good when printed, gl anon.
