As I have been reading the problems encountered in hydrographic printing, it appears to me that the most misunderstood part of the process is proper hydration and activation.
I have seen @K2Concepts
repeatedly respond with "underactivation is not just too little activator" but can also be caused by under hydration.
I have also read that certain films need 90 seconds, 2 minutes and some, even more time to hydrate properly before activation instead of the standard 60 seconds.
With that in mind, please explain exactly what I should be looking for in the film that confirms proper hydration?
