I have a logo that was done with RGB colors, now I have to work with this logo to do something for printing purpuses, the problem is that in the RGB version of the logo I have a shade of green I cannot reproduce with CMYK… How do I do it?
I googled up a bit and found some CMYK values that would create a simmilar green, close enough, the problem is when I put those values in Illustratot(%C %M %Y %K) I don’t get the color I am supposed to… what am I missing ?
I have an image to illustrate my problem :
The green I want to create in CMYK is the first green, when I put those values there I get the second green you see there, when I print this image will I get something close to the first green ? …And this is simply how you view it on screen, a bit darked and washed up ? pom pomm pom pommmmmm
If I open up my logo in Photoshop and go to View > Gamut Warning the green part of my logo shows up in grey, to ged rid of the grey I lower the saturation, the problem is lowering the saturation ruins my nice bright neon green…
If anyone around here printed neon green, how did you do it ?
I found on some forum someone saying that Pantone 802 C will print neon green, I looked it up, selected it and on screen it looks worse than my second green in the sample image… and anyway, putting a pantone color in a PDF that will be printed on a regular simple printer is any good ?
[The material the logo will be printed on will be downloaded by various users over the internet in PDF format and will be printed by various home normal hobby printers, so I will not have the control over that at all, I just want a green that will print neon/led green or something closer on a regular hobby printer, not in some fancy color lab/printer. Its imposible isn’t it ?]
Short answer: you can’t.
RGB is additive. The more color (made of light) you add, the closer you get to white.
CMYK is subtractive. The more color (made of ink, which is reflective, which subtracts light) you add, the closer you get to black (or actually a muddy brown).
CMYK has a smaller range, or gamut, of colors it can reproduce than RGB does.
What you can do about it:
If you need that particular neon green to print, you’ll need to find a spot neon color and specify that for your printer. That means the ink will be premixed to create that neon green, and will be laid on one plate, instead of mixing CMYK inks to achieve it. It will be a fifth color, and will cost extra.
