OPRC

NELA Brüder Neumeister GmbH (Booth 1461) is introducing a register control system, OPRC, for the newspaper industry. OPRC can control the lateral and circumferential register by analyzing a micro CMYK mark printed on the web. The mark registers to black for both quality and cut-off registers. Using the industry standard Prime Network communications protocol, OPRC can easily interface with most major press control system suppliers, such as ABB, EAE, and Harland Simon. Alternatively, OPRC can use PLCs to control register motors directly.

Register marks can be located anywhere on the web and are viewed by a CMOS camera that uses both white and blue LEDs to capture all of the color marks on all grades of newsprint. The camera contains on-board processing and sends register error values to a server PC, which in turn calculates and communicates correction commands to the press control system, or to a PLC which controls motor movements. The camera housing is designed to withstand harsh environments and uses a remotely-controlled film to eliminate manual cleaning of paper and ink dust from the lens. The lens film roll holds a 3-month supply of film and is easily replaced.

OPRC can be installed as a “stand alone” system or integrated into the existing press control system on a single wide, double wide, or triple wide press.
