Troubleshooting
Main rollers
These are the rolls that perform the actual
lamination. They are rolls capable of being heated in
thermal roll laminators and are usually larger in diameter
than the pull rolls.
Media
Term used to describe the materials used to
print an image, i.e. the papers, inks, toners, etc.
Mount adhesive
A term used to describe a two sided pressure
sensitive adhesive used in mounting images to various
substrates. This material can come with one or two
release liners and may be optically clear for face
mounting applications.
Mount tissue
A thermally activated mount adhesive used in
either a vacuum or roll type laminator. Primarily used for
mounting bond type papers to porous substrates.
Nip
The interrelationship of any two rolls. The
distance between the closest points of the two rolls is
referred to as the nip of the rolls.
Outgassing
The term that describes the phenomenon where
the heat from the laminating process turns components
of the printed media into a gas. This is seen as a cloudy
or murky finished image. It can also be caused by a
chemical incompatibility between the overlaminate’s
adhesive and the printed media.
Pull rollers
These rolls provide for 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 Falcon 160 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.
