well, after I couldn´t get super reliable white with discharge, i switched to waterbased ink. Was a bit nervous about opacity, but: preflashed the shirt and first stroke already very nice white, then flash, print again. I flash again to take the shirt savely from the pallet to a drying rack and later to send them all in one go through the conveyor dryer.
I let the shirts go 2 times, each 160 degree C for around 1.20 min. After that I stretched it: cracking. Decided to send them two more times: this run with 180 degree C and 1.20min. still the ink cracks. Pressed them in a last effort with the heat press for 30 sec at 160 degree. still cracking. (did 99 sec on a test-shirt: still same outcome)
I read that I can:
- overheat the ink (but after 2 runs in the dryer it was already cracking?)
- use too much ink?
- not getting the ink deep enough? (i already used a 43t and a lot of force)
Is there anything else I can try now? or is it learning experience and I have to do it again?
