Through 15 years of research, development and Teamwork, Jet USA Corporation, Jet Europe, BV and Jet Ltd. have teamed up to become one of the world’s leading suppliers of photopolymer printing plates.  Manufactured by TOK in Japan, Jet Water Washable Series Photopolymer Printing Plates are available in a variety of thicknesses, backings and hardness to suit a wide range of printing applications.

The Jet Water Washable Series Photopolymer Plates have become well established as one of the most environmentally friendly plates on today’s market.  Jet Water Washable Series Photopolymer Printing Plates are made from a 70% poly vinyl alcohol and acryvinil monomer, which dissolves in water and can be safely flushed into the drainage system.  They do not contain any nylon photopolymer and therefore have a high solubility in normal tap water, leaving little residue, which

Guarantees easy, reliable and environment friendly plat making.

In addition to having a cleaner plate and sharper image reproduction, Jet Water Washable Series Photopolymer Printing Plates are quick to process and have a long printing life, making them ideal for repeat printing.
