Webbing

For most processes the machine must be webbed before images on thin film or on panels
can be processed. The machine can be webbed for single sided or double sided
processing.
Note:
In single sided processes adhesive residues will stay behind on the bottom roller where
the film is wider than the images. To prevent this, use film of the same width as the
image, or a release liner of the same width as the top film can be used in the bottom
section. The release liner can easily be removed later on.
In the bottom section both shaft positions are unwind/wind-up combination positions that
have to be set as an unwind or wind-up position.
When processing panels, a leader panel (waste panel equal to the panels to process) is
needed to feed in the film and set the pressure and tension.
When processing thin images a release board is needed to feed in the film. When this
panel is through, the nip is set to zero and the images can be fed. The release board is
then cleaned and can be used again.

3. Pull the film forward until approximately 10 cm (4 in.) is on the in-feed table.
If the film has a release liner:
•
Peel off the release liner.
•
Pull the release liner up and stick it to the scrap core on the wind-up shaft.
4. Stick the leader panel to the film and feed the panel into the nip using slow mode.
Note:
Use a release board when processing thin images without using carrier boards.
