Hi, I've recently started printing on sub ceramic tiles and been quite pleased with the results.
But today I've had three crack on use although they were printed a week ago and have been handled since.
Any ideas on what I might have been doing or is it likely to be just applying too much pressure when printing?

They may be to cold when you press them. Or do you cool them by dunking in water?

heat them up for about 15 secs before pressing and leave to cool naturally.
