Printing is the process of reproducing images and texts on a durable surface. It is also used for wallpaper and textiles. In addition, printing has evolved to become an important part of paper-based publishing.
The term printing is commonly defined as the reproduction of text and illustrations on a flat or curved surface with ink. The process involves a number of moving parts, and may involve the use of an industrial press.
The basic elements of the printing process include the following:
– the ink or color is transferred from a printing plate to the paper. Depending on the process, the ink is either opaque or translucent. Paper is often coated, either with a matte finish or a gloss. This coating increases scuff resistance and adds durability.
– the final image is then printed or inserted into a magazine, catalog, or other type of publication. It can be applied on a variety of surfaces, including paper, cloth, and glass.
– the paper is coated, allowing the ink to be pushed through a mesh opening to create a raised surface. Coated paper is generally thicker and bulkier than other papers.
– the ink is then removed from the non-image areas of the print job. Dampening is used to repel ink from non-image areas, ensuring that as much of the paper is used for printing as possible.
– the ink or color is then separated by a color separation system. This can be done manually with screens or filters, or digitally with a software program.
