I've just had one of THOSE days...
Had my casual guy in doing these prints so I'm not sure of everything that happened. The print is on poly/cotton hoodies with white underbase and highlight white (Sericol multi purpose low bleed). The dryer had an issue halfway through the job where it lost temperature and the hoodies weren't fully curing. So I fired up the heat press (330 for 6-10sec, med pressure) to make sure the prints were cured and this happened: the white parts of the print stuck to the Teflon sheet and delaminated while the gold print was fine.
This is the first one and worst example because it surprised me, the rest I pressed with much lighter pressure than normal and peeled carefully so they look okay BUT I'm worried that they are going to fall apart in the first wash.
To me it looks like the underbase might have been over flashed and the issue is unrelated to my dryer/curing problems. However perhaps I've missed something else?
I'm going to give this hoodie a wash tonight to see how it goes, but is there any way to be confident the other hoodies will be fine? Any ideas on what went wrong?
