Pull rollers
These rolls provide tension of the laminated media.
Tensioning of the laminated media helps to make it flat
and smooth. In most laminators they may also be used for
cold mounting and laminating applications. Usually these
rolls are of smaller diameter than the main rolls.
P.S.A.
Stands for Pressure Sensitive Adhesive. An
adhesive that requires no heat to activate, only pressure.
It is employed by removing a protective release liner and
then pressed onto the material to be laminated. This type
of film is commonly used on materials that are temperature
sensitive.
Release liner
A coated paper or other media used to protect
the adhesive side of a pressure sensitive material.
Rewind
A system that rolls up media. The rewind tubes
used on the Orca 1600 laminator is a prime example.
Scarring
The visual effect of folding papers or laminates
and breaking the surface. When done to a printed material
it will be seen as a white crack in the image.
Second surface
A term to denote the back side of a substrate.
Commonly referenced when discussing front mounted
images to a clear substrate with an optically clear mount
adhesive.
Silvering
A term used to describe one of two occurrences;
1) air bubbles trapped between the product and a thermal
laminate, generally caused by insufficient heat being applied
by the laminator or 2) the adhesive is not fully activated in
a pressure sensitive film, which will disappear once the
adhesive is fully activated. This activation process can be
sped up if a small amount of heat is applied during the
application.
Substrate
The material to which an adhesive is to be bonded.
In film, the substrate is the polyester and in mounting, the
substrate is the material being mounted to.
Tunneling
When a laminated image is rolled up for any period
of time and the laminate separates from the image.
Generally in a pattern that follows the direction the
laminated image was rolled up in. This is very common
with pressure sensitive laminates and finished products
that have been wound tightly.
Unwind
A system that unwinds media. Unwinds are used
on all laminators to dispense laminate for lamination.
Web
The path that rolled media unwinding from a supply
roll takes through a machine or array of rollers.
