Description

A plastic woven cloth printing machine

technical field

The invention relates to a plastic woven cloth printing machine.

Background technique

At present, roll-to-roll printing generally adopts flexographic printing technology, and the principle is the same, including pre-press feeding unit, printing unit and winding unit, and also has a tension control unit, but in printing such as double-layer plastic woven cloth When using high-quality printing materials, the tension is difficult to control, which makes it difficult to control the printing color registration accuracy. This is more obvious when the printing speed is faster and the printing length is longer. Moreover, the printed materials after printing must be dried by a drying device. Due to the thick thickness of the double-layer plastic woven cloth, the heat absorption is large, the drying time is short and the effect cannot be achieved, and the plastic woven cloth softens after a long time, which affects the printing quality of the reverse side and restricts the use of flexographic printing technology on this type of printing materials. .

Contents of the invention
