I repress for 10 sec. I also give the garment a little "stretch." The idea of the repress is to fix and partial lifting of the image that happened while peeling.
I recall someone mentioning that technique long ago. Never got around to trying it myself, but if the end result is equally good, I see the merit. No worries about trying for perfect peeling angle and speed--or fumbling with getting the corner started. And it's a peel and stretch all in one. I'll have to remember to give that a try.4. Once you open the press, grab the shirt immediately and stretch it from all sides as fast as possible.
The re is no need to peel the transfer as it will fall off on its own by the stretching.
Obviously you need to grabbing the shirts from the areas not covered by the transfer.
