Method and apparatus for registration mounting printing plates

摘要

The device comprises a table (16) mounted on a stationary base. First and second camera assemblies (18,20) are arranged adjacent to the table and are connected to respective video monitors (24,26), for viewing identification marks formed on the printing plates. The camera assemblies are independently moved relative to the table, by using linear actuators. A motion controller (32) which is connected to the linear actuators, generates signals corresponding to the marks formed on each plate. Each plate is positioned on the carrier sheet so that the marks are aligned with the images formed on the monitors.
