Steve - If I can offer some guidance.....Manufacturers must publish guidelines that they KNOW will work. I spent 25 years at Wilflex, and I assure you that although every cure recommendation for a normal plastisol is 320f ... Many times it is lower. The 320 gives a safety barrier if you will. Also pigments and loadings are a factor in cure temp for plastisol so you need to state a temp to encompass all colors in a range.But enough about plastisol! Temperature, time, air flow, all play a role in curing discharge. I would suggest you experiment with some consistent printing methods, controlled dryer settings, cure the discharge, document with a sharpie, and wash test several times. For instance if the recommendation was 320 for 3 minutes -- maybe try 4-5 variations - say 330 for 1.5; 340 for 1; 320 for 3, etc. This methodology can help to give you a base line.But remember, if you do this on a day where the humidity level is 25 in your shop; wnd then run a job after the rain in the summer with the dock doors open and rh at 80% -- well those cotton shirts absorb a lot of moisture and your curing specifications can change. You must drive out all the water from the ink film.I would be interested to hear Tony and others thoughts on this.Thanks and good luck!
