5.3.2 Loading shaft with film rolls
The film roll is put on the shaft depending on the type of film and the use in the upper or lower
section of the machine.
In general pressure sensitive film with release liner (A) is rolled up with the liner (3) and adhesive
(2) to the outside of the film (1), whereas film without release liner (C) has its adhesive layer to the
inside of the roll.
However North American pressure sensitive films in general have the release liner on the inside of
the roll (B).
Figure 11: Film rolls.

In the upper section, the adhesive (2) side in contact with the image and the release liner (3)
must be on the top when unwinding the film to the front of the machine.
•
In the lower section, the adhesive (2) side in contact with the image must be on the bottom
when unwinding the film to the front of the machine.
