Marco,
Just had another thought if it is only your contacts. If you are using a
single sided glass exposure frame with a flexible membrane over the top,
your copy film will be in contact with the membrane and will tend to get
mechanically stretched. This would result in an apparent shrinkage after
exposure. If this is a possibility, put a sheet of black card on top of
the film before closing the lid and pulling the vacuum.
Hope this helps.
