Today, there are three main types of rotary presses; Offset , Rotogravure , and flexo (short for Flexography ). While the three types use Cylinder s to print, they vary in their method. Offset Lithography uses a chemical process which an image is chemically applied to a plate (generally through exposure of photosensitive layers on the plate material). Gravure is a process in which small cells or holes are etched into a copper cylinder which are filled with ink. Flexography is a relief system in which a raised image is created on a typically polymer based plate. In Stamp Collecting , rotary press printed stamps are sometimes a different size than stamps printed with a Flat Plate . This happens because the stamp images are farther apart on a rotary press which makes the individual stamps larger (typically 1/2 mm to 1 mm). |
