As an experienced manufacturer of precision long printing cylinder, including steel roller, aluminum roller and EPDM rubber covering rollers, we have closed cooperation with several famous wide format digital printer customers.
Key attention for qualified printing sleeve rollers:
1) Concentricity and total run-out: precision grinding is a must to have a good result <=0.05mm (up to 6,000 mm length) for both steel roller and rubber covered roller.
2) Static/Dynamic balancing is also helpful for keeping good run-out.
