Think it's sorted. I need to try it out printed on the final paper, but I'm happy with it. I want it to be slightly darker than the white background just for it to stand out slightly, and the creases in the paper and the join marks are still visible which is exactly as I wanted. Progress.
Genuine dilemma over whether to have the main cover as a kind of realistic billboard, complete with overlap marks, or to just have the plain text on a plain white background. Help! What do you reckon? [click on images for bigger view]
