Pressure sensitive laminating became popular with the advent of wide format inkjet printers, many of
which use silicon oils when printing. Thermal laminate will often stick poorly, or not at all, when
trying to laminate some of these types of prints. If you prefer to laminate an inkjet print with thermal
film, it is recommended that you test laminate a sample of the same paper and ink used first. Also
note that the drier the ink, the better the adhesion.
The choice between Thermal or Pressure sensitive laminate depends on many factors :
Do you require full encapsulation?
Will the item to be laminated accept thermal adhesive?
Is the paper or ink suited to heat exposure?

Thermal or Pressure Sensitive laminating?
Selecting laminating film
The Centaur is designed to provide reliable high quality laminating on a wide range of film thicknesses
and for many different types of paper. When laminating you may encounter a wide variety of items to
be laminated, on many different grades of paper and in conditions ranging from brand new to old and
damaged.
Laminating is much the same for thermal and pressure sensitive applications. The following section
shows how to laminate, with explanations where the process differs for thermal and pressure sensitive
laminating.
If you are an experienced operator of laminating machines, much of the following information will
already be known to you. If you are a first time reader, we strongly recommend that you carefully read
the following and make sure you understand the process involved. While laminating is not
tremendously difficult, it is important to understand the technique involved.
If you are new to laminating, you should expect that there may be some losses during your first
experience with the laminator. Consider this the cost of training yourself to be a good operator, and
don’t begin laminating with an expensive print! Practicing laminating with a few sheets of newspaper
will pay for itself as you gain experience.
Whether you are laminating using thermal or pressure sensitive film, it is recommended that you always
use a high quality laminating film.
High grade film behaves more predictably during laminating, and gives a much better result. Very low
priced film may seem attractive, but can cause problems, loss of items being laminated and excess
wastage due to difficulty in tuning the machine to run the film properly.
A more expensive film will often be as economical as a cheap film, as it can be tuned easily, will run
predictably and result in less wastage.
