thanks for the response.
I use a coordinate measuring machine and measure four corner points on the
photo tool. At first, I get the dimensions of the master film (X1,X2,Y1,Y2)
and then compare this with the dimensions taken from the contact film. The
contact film always show about -30 to -40 micron reduction in length.
