What is the best way to convert a graphic form RGB to CMYK? Do I need to select each item or can I do batch convert?
Is the graphic vector, image or a combination?
It's a combination of text with a photo with a linear transparency fading into a grey backgorund
Text and vectors can be changed with the find replace commands, a photo simply can be selected and mode changed, the grey background if it's vector can be selected and the color simply changed, if it's an image then it's a mode change however I suggest that you remove the lens first.
All of this can be done on the fly if you publish to PDF via the export tools.
