What screen mesh? How thick is your emulsion? If you can get by with two ink coats, you will get a better finish. It might help to go a little longer on the flash, a little beyond the jel stage, even up to 260 degrees F. Doing this with the first flash helps greatly with fibrillation, holds the fibers of the fabric down for subsequent print passes. It might also help eleminate the need for the third print stroke. God Bless.
