What is the thickness of your film.  You should be using 7mm,
nothing less.  3mm will expand and contract almost at will.  You
should also store your film in a humidity and temperture
controlled environment.  Don't measure the film immediately
after it comes out of processing since it has expanded during
drying.  It will stabilize back to original size shortly.   If you
photoplot your own artwork, is your photoplotter in a stabilized
environment?

Hi Guys,

I have a problem with dimensional stability of photo tools.  The
photo
tools shrink after processing.  I've tried increasing the drying
temperature (50-55C) just so it will not shrink but it still does.
This is
really giving me a headache.  Any suggestions?
