Initially, printing was done by hand-painting the films during the 1930’s. Later during the early 1980’s computers were used to create camera ready film. After offset printing was technique was discovered during the early 20th century, production units started printing using offset printers.
Offset printing is an indirect printing process, where the ink is not directly applied from the printing plate to the paper instead indirectly through a roller. Before printing four plates are prepared for each CMYK ink, plates are made of aluminum and are millimeter thick. The area which is not to be printed contain thin layer of water.

The adhesive used to combine the two substrates together will be applied to either one of the substrates, and then dried in an oven prior to being combined with the second substrate. The two substrates are combined after the adhesive is dried for maximum efficiency of the dry bond lamination process. Dry lamination is also known as thermal or dry lamination.
There are different types of lamination:-
Matt lamination – Matt lamination is a flat finish on the printed papers, that gives it that “matt” effect. It’s very durable and stops cracking and marking, thus giving a longer lifespan to the print.
