Reply To: Exporting Different Color profiles from one document

Interesting idea. Perhaps you could make 2 spot colors:
“blue rgb”
and “blue cmyk”
The blue RGB would be a spot color specced with RGB colors; the cmyk blue would be a blue specced with CMYK colors. You’d assign RGB blue to everything. But when you want it to export using CMYK, you would use the Ink Alias (in the Ink Manager) feature to alias the blueRGB to blueCMYK… and then set the blueCMYK to separate to CMYK.
