Troubleshooting

Legacy Documents with Both RGB and CMYK Objects

I opened one of my old Illustrator files and got a warning that the document contained objects of both CMYK and RGB color. The warning box wanted me to change them, but I was afraid of messing up my artwork, so I clicked Cancel. What should I do?

The Convert Color Mode dialog box is, indeed, formidable. Illustrator 9 allows only one color mode per document. Here are the guidelines for choosing between RGB and CMYK: If the document is intended for a four-color process printing job, click CMYK and let Illustrator convert your RGB colors. Any colors that were outside the CMYK gamut (and would therefore not be reproduced by the four-color process inks) are converted to the nearest CMYK color. If you don't plan to use the document in a four-color job, select RGB. Because virtually all CMYK colors fall within the RGB gamut, no conversion is necessary.
