How Does Flexo Printing Work?

 

Flexographic Printer

There are a number of different types of flexographic printers, usually set up to accommodate special printing needs. The basic principles employed tend to be the same from printer to printer. Effectively, there are three rollers involved: a meter roll (so called because it meters the amount of ink applied to the plate), a roller with the plate attached, and a impression roller. The meter roll applies a predetermined measurement of ink to the plate. The plate is subsequently scraped by the doctor blade. The substrate (the material to be printed on) is passed between the print plate and the impression roller, which applies pressure to the keep the substrate against the plate.

Substrates

Flexographic printing can be performed on a wide range of materials. Historically, it has been used to print on cardboard and food packages. Today, virtually any type of substrate can be used in flexographic printing. Some of the more popular materials are plastic, paper, cardboard (still) and cellophane. It remains widely used in newspaper, catalog, label and packaging printing.
