So I was in my college class last night. It's basically a class to teach us about pre-press work. We started talking about knockouts and overprints.
My instructor said something to the effect that if you do a process job and you have a field of color that it is a good idea to trap it in a process job.
This makes no sense to me beccause I thought trapping and choking was more for doing spot color jobs.
If you do a process job wouldn't the halftones blend the field of color into the background?
