Step 7:
Enable all the available options namely Belt Dryer, Print Dryer, Spreader, Jetting, Brushing, and
Washing by selecting them, as shown below:

Now, the washing process gets started.
Glue Description
Glue is composed of three different chemicals and two solvents.
Note:
Generally machine comes with the glue coating. In case, glue adhesiveness is reduced, then recoat it
by following the instructions mentioned in the below section.
Chemicals
:
•
Prima
: It is used as a primitive coat, for smoothening the belt surface. This is to be done only when
the previous glue layers have been washed completely.
•
Therma
: It is used for an intermediate coat, for activating and deactivating the glue according to the
temperature variation.
•
Perma
: It is the final glue coat, to make the belt sticky for the fabric.
Solvent
:
•
Cleantek
: This liquid solution is used for the renewing/refreshing the tackiness of the Perma
adhesive. In digital printing, the adhesive film must be even, thin and hard (to maintain accurate
distance in between print head and fabric). The Cleantek removes foreign elements, like dust and
micro fibers, from the top layer, hence enhancing the adhesion property of the Perma. If there is no
improvement using the
Cleantek, it means it’s time for a coat of the Perma.
•
Solvtek
: This is used either to dilute the adhesives, or to complete removal of the all adhesive layers.
The following are the two main reasons for removing all the glue layers:-
o
When the thickness of the adhesive layer goes on increasing due to multiple coat of the
Perma.
o
When the glue layer feels smudgy or groovy (in terms of evenness).
