This scraper is the first generation scraper, the scraper made of ultra-high molecular weight (UHMW) polyethylene. This product has become a standard for printers and OEMs in the corrugated paper printing market since its launch.

This scraper can reduce adjustment time and form a uniform ink film on the entire surface of the mesh roller, which has been proven to reduce dot expansion and provide color matching, whether printed with water-based ink or UV ink. That means you can improve your printing productivity and revenue while reducing material waste and quickly converting tasks.
