Just a couple of quick Ideas without diving too deep into the situation.
1) Do you stabilize the film (open the package and "fan" it) for 24 hrs before using in
plotting. This should be done in the plotter area
2) Are your humidity and temp in the plotting room and other areas consistent with each
other?
3) Some material movement from the processor is normal (1-2 mils over the sheet of film). If
your shrinkage is constant, size at the plotting/cam station according.
There are a number of other items that will also cause this, but start simple... JOHN WAITE
