I am submitting a file for a CD face design. The printer wants three colors. I understand I need to give them a layered document, with each layer representing one of the three colors. I want to avoid overlapping gradients and my design is simple enough to do so. But when I look at my channels, I see that even the black in my document is presently a mixture of different colors. For example, when I toggle on/off the "yellow" layer, the black in my document changes, as though there were yellow in it.
Help!!! How do I do this?
