 Re: Process screen printing - Photos
Calibrating a press is like tuning a musical instrument. Calling the manufacturer of the strings you are using, will not tune the instrument. At some point you just need to play a note, and turn the peg, play a note, turn peg and keep repeating the process until the setting produces the desired note. Postscript contains a transfer function for the same reason a guitar has tuning pegs.
For screen angle, i would suggest you measure the output angles and verify that you are getting out what you are expecting. The best way i know to do this is to scan the film on a flatbed scanner and measure angle and frequency within photoshop.
I'm still working on the white underbase. We've moved to a 156 mesh, from the 110. While not bulletproof, it is still bullet resistant. We're about to start testing things like soft hand additive.
In my brand testing, i saw that the brands have different bleed though characteristics. The shirts with the least bleed also had the softest hand. Hanes was the best, fruit of the loom was good and others were worse.
