Hi Marco,
    What Paul is referring to is if the drawer has a glass base, and the top side has a mylar.
It sounds like you have a "glass pac" style tooling.  AT what point do you see the "distortion".
Is is off the diazo developer or during exposure, or after transfer of the phototool to imaging
area.  Also, are you using a covercoat over your diazo (IE- APF,PPF, etc).  Sorry about my
misinterpretation.  I thought you were using 1st generation silvers.  JOHN WAITE
