Sep, 14 2017

Screen printing ink layer has strong covering power, but the details of the performance is poor. Letterpress printing ink layer in thinner, but the printing precision is high and printing speed is fast. As a result, the printing of the molded tube is mostly letterpress printing. No matter which kind of tube, the Color Printing Machine has the same characteristics:

1. Use photosensitive resin relief plate and print as negative film.

2. When printing, use supporting tube core counter tube diameter as the bearing pressure roller.
