I pressed one with medium, heavy pressure instead of light (without the cookie sheet), and it seemed to work much better (only leaving a few speckles). If I had used the cookie sheet it might have worked, but I didn't have enough time to test another one until tonight.
I haven't checked to see if my press is bowed slightly in the center yet, but it seems the heavy pressure setting is straightening it out a bit. But isn't heavy pressure not good for just a polymer transfer?
And is there a way to straighten out the press if this is the issue?
btw, I believe the brand name is Mighty Press. | |  | |  | |
Some uses the same pressure for both pressing and claimed to get away with it. The way it was described is: set the pressure with the shirt on the platten, use the same pressure for pressing the two papers. The reasoning behind it is when the press is set with a shirt then the pressure is less when pressing the two papers due to the thickness between the shirt and the papers. Patchmaster is one of the members that uses this method. He claimed that it does not affect the outcome. Try want sending him a PM.
Regarding uneven surface I am not aware of a fix except using a soft pad that will compensate for the defect of the surface. Stahls sells an industrial grade silicon sheet that can withstand high temp or try using stacks of silicon baking cookie sheet. There is also a TeePadIt.
Another thing to look for is uneven surface of the lower platten. This can happen when the press is used for pressing hard goods which can create indentations on the pad.
If you are getting good prints by pressing heavy during the first press by all means use it. The outcome is more important with the process that works. It is assumed that no two sets of equipments are alike.
