Hi all, I'm currently designing a logo to be used on printed paper bags, business cards etc. It has a light green colour as its background (search for 'darkseagreen1' here http://www.december.com/html/spec/colorcmyk.html). When I'm in RGB mode, I can create a pdf, send that as a test to my printer, and it comes out very nicely indeed. Not far from the bright green of the RGB on screen, all good. So I know that that shade can be reproduced with CMYK printing - it is within the realm of possibility at my printers. But, when I convert my Illustrator document to CMYK mode, the colours of course come out darker. So I try playing with the CMYK values to get to an approximation of the green I like, and it's impossible. Not even close, the nearest I can get is a much greyer version which is completely unacceptable. So it appears that Illustrator's interpretation of what is possible with CMYK is very far away from reality. I know I can print a certain shade in CMYK that Illustrator can;t even come close to showing on screen. So I guess I'm going to have to convert my files to RGB before creating a pdf to send to my printer because that's the only way I can create a pdf with the right shade of green. This seems crazy to me! Has anyone had a similar experience? Got any advice on how to work with a colour that is possible but Illustrator doesn't recognise it as possible? Any thoughts much apprecaited, Thanks!
