In the end, they are again exposed to UV light to harden them and make them stable for the printing process. The plates are then cleaned with water, and they are then cooled off. The platemaker machine then exposes the plates and litho film for UV lighting to transfer the graphics on to the printing plates.

Then the litho film photography is put over the plates and put into the platemaker machine where they are covered with a vacuum sheet. The printing plates are made by first turning the graphics into a litho film using a film processor.
