I print on TJ paper with MM inks.
I have printed inkjet transfers and not pressed them for up to two months.
This often happens when charity groups order transfers for a special event. I then rent them my press and supply them with blank shirts. They press them at the event as they are bought.
They may get 100 transfers from me, but not press them all until after 2-3 fundraisers, which can take a month or two.
