Lamination refers to the process of adding a film to one side or both sides of prints. It is very useful and necessary for many products, including business cards, posters, calendars,maps, photographs, menus, price tags and many others.

The application of lamination often serves the following purposes:

1) Lamination adds luster or gloss to a printed product.
2) It provides stability to the sheet, allowing it to be more durable or stand upright.
3) It provides protection to sheets that are handled frequently or may encounter moisture.
4) Many laminated documents are waterproof, tear proof, and tamper proof.

Although it is very popular to produce prints with lamination for its various strong points, you still need to pay attention to the following tips before printing

1) Allow several days for laminated sheets to cure, since the adhesive takes time to fully adhere to the stock.
2) Use caution when applying a lamination film to varnished sheets. Use a varnish that dries quickly, contains minimal residual solvent, and contains no wax additives.

3) Do not laminate printed materials containing metallic inks since air bubbling adhesion problems may occur.
4) Use caution when a significant amount of anti-setoff powder has been sprayed on the sheet during printing because it causes adhesion problems.

It is a means or tool for placing ink on paper. Most printing is done with a plate. The four main types of printing methods are relief, where words or images are raised above the surface of the plate; intaglio, where they are etched through the surface; planography, on the same plane as the surface; and stencil, or screen printing, cut below the plate surface.

Words and images may also be “printed” electronically, using photocopiers and inkjet printers. See also electronic printing, intaglio, letterpress, lithography, offset, planography, plate, relief, screen printing, stencil, waterless printing, and web press.
