Re: [PPLetterpress] Re: thin lines are curling and plates too soft
When we use this material, I turned the dryer heat down and basically let the air blow over it at room temp until dry. I also preexpose the back, as Harold mentioned, but even longer. Then cut the main exposure time down a bit more than half the time normally allotted. This provides a better shoulder, but even under pressure you will find letters move around etc...Generally it is not hard enough for most of the work we do. Have you tried the KF95 to see if it has the same issue or does that not provide enough relief.
Has anyone tried the Miraclon MF152?

I have had this problem as well with processing KF152 plates. I usually am processing
illustrations and I when I use isolated hatch marks they will sometimes float around the plate
changing their position. There was once a post about moving periods and commas in this
group that described the same problem. Somehow the upper material lifts off the base.
Like the original post, my plates look fine when i remove them from the washout. It is after
the dryer that I notice the problem. I had assumed that it was due to the dryer and so I now
dry my plates for a very short time. About 2 minutes. and I take them in and out during this
2 minutes to keep them from getting too hot.
Can somebody please tell me what the purpose of putting the plate in the dryer is? If you do
not plan to use your plates for a few day and can leave them in a place to dry slowly, isn't
this good enough?

Well then, since I was at it long before you (and gave you a ton of
advice), perhaps you are competing against me? Sort of a straw dog
though. Or maybe I should start thinking of myself as the alternative
