Noob question on color separation file prep
Hey all, I just joined a local printing co-op and gained authorization to use their Riso RP 3700 Risograph. I wanted to ask about prepping my files so that I'm not wasting my paid time on fixing my files there. I've read some guides, like Risotto Studio's. Here's what I was planning on doing.
I had bought a ream of 67lb cover stock, but would like to go thicker to an 80lb cover.
First pass as florescent pink. I've been reading that you don't want more than 75% coverage for large areas, so based on the co-op's color guide, I'd probably have the main area at 60%.
Second pass as yellow. I'd love for it to be at it to be a higher percentage, but will have it at 75% due to issues I've read about.
Third pass as black.
Here's my main question. Would it be ok to overprint a 90% black on top of those colors, or should it be knocked out? I was thinking for ease of registration, the background into the nose and the background into the toga would be a continuous orange, and the black outline and the circle with the line through it would all be overprinted. Will that work and look good?
Do you see any other issues that I should avoid or have any other tips? Thanks for any insight!
