What is laminate?
Laminate is used to protect printed surfaces. In fact, lamination is applying a thin layer on front or back surfaces of a printed sheet, which protects it against moist and temperature changes. Laminate is in liquid form, and variants of laminate liquid indirectly print on different surfaces.
In the market, there are special categorizations concerning lamination methods and processes; for instance, varnished and pale, or cold and warm. But the method basically includes protecting with plastic layers. Here plastic layers, too, have special characteristics in terms of thickness
(in microns) and dimension (rolls or sheets depending on the equipment).
Laminate is not printing. After the surface is printed, it will be pressed or laminated. The Company does this in different widths with the equipment it has. There are two types of laminates, warm and cold. The cold variant is thinner, more attractive somehow, more delicate and more expensive. While the popular laminate is the warm one which is used for bigger surfaces called large-format or plot. The most usual method is warm laminate whereby the plastic cover is pulled over the surface with heath. This method was also in practice in older times, and was called pressing, used for smaller surfaces. Current devices are mostly roll machines, and may be found in Iran in printing companies equipped with digital printing machines. Lamination with this method takes place in two varnished and pale variants, and back and front surfaces may be laminated in both ways.
The cold method is used more for protection of printed surfaces and creating artistic effects. The Difference between this method and the warm variant is lack of heath and application of a very thin layer in this method. It is in a way a form of cellophaning. This is also possible by spraying special polymeric material, which is called coating. Basically, after plotting the printed surface, it will be laminated. Lamination improves color intensity and contrast in printed pictures. Printed pictures with bright colors indicate higher quality. Laminate protects the printed surfaces against wrinkles, stains, sunshine, darkening, paling, fat stains, fingerprints and other environmental damages. Lamination is done by lamination machines which exist in various models with different qualities in Iran. Therefore, before choosing your printing company, observe the machines and make sure of the quality of the material used.
