The printing plate used in flexographic printing is flexographic, also known as flexographic. At present, rubber sheets, flexible photosensitive resin plate and thin flexible photosensitive resin plate used in corrugated box printing are all examples of flexography. There are three kinds of flexography, namely rubber plate, liquid photosensitive resin plate and solid photosensitive resin plate. According to European and American market share statistics, the market share of rubber sheet and liquid photosensitive resin plate is relatively small, accounting for about 15%, mainly used for printed parts with simple design. Printing plates made of liquid photosensitive resin can be used to print corrugated boxes and some news newspapers. Rubber sheets are often used to print parts with special requirements for solvent resistance of plates.

Solid photosensitive resin plates account for more than 85% of the whole plate market and are the mainstream of flexographic printing in the world today. In the field of packaging printing, its printing quality can be comparable to offset printing and gravure printing.
