Are there different inks that have different characteristics when it comes to peeling hot or cold?
I've seen instructions for both methods.

Hot or cold peel is determined by the coating on the film. The hot peel coating releases easier from the film. Therefore, you can peel before the powder has cooled fully. The powder/transfer adheres better as it cools down. You can get away with a hot peel on cotton but on many fabrics it is best to wait for the transfer to cool before peeling no matter what type of film is being used.

Even though SuperColour say their transfers are all hot peel, we always peel them cold. As a matter of fact if we would hot peel them a lot of them don`t adhere that well, unless we crank up the pressure to 100 psi.

For transfers with powder and hot/warm peel temperature is very important. If you are too high powder is still liquid when you try to remove film. And will not transfer nicely. If you are in the right temperature range, within short time between opening press and removing film powder solidifies just enough to make good bond with textile.
