LASER-ASSISTED ALIGNMENT OF MULTI-STATION FLEXOGRAPHIC PRINTING SYSTEM

摘要

A multi-station flexographic printing system includes a plurality of flexographic printing stations. Each flexographic printing station includes a flexo master. Each flexo master comprises a Fresnel zone pattern in a unique position. A method of aligning a plurality of flexographic printing stations includes printing a Fresnel zone pattern on a substrate in a unique position for each flexographic printing station. Light is directed through the Fresnel zone patterns on the substrate. The light focused by the Fresnel zone patterns is captured with a sensor device.
