Question
Hi, i'm in charge to design a yearbook but i have no experience in printing. i've contacted the printing company and they need my files converted to CMYK color in pdf files. Could you help me with the steps for converting from RGB to CMYK in CS4? i've tried it in gamut warning and desaturate the grayish tone but the color seems to desaturate. After convert to CMYK, i adjust the level and increase the saturation but i'm afraid the color won't be the same after printing..please help.. thanks..

Answer
Hi Brian,

Open a copy of your image and go to Image>Mode>CMYK Color. I say open a copy because once you've converted to CMYK you cannot go back to RGB, CMYK is a smaller color space and some of the bright colors will be lost.

Make sure you see a color accurate proof from your printer.

Hope this helps,
