Method of determining the area coverage of a printed original or printing plate for printing presses

摘要

A measuring device which is equipped with a number of sensors determines the area coverage of a printing original or printing plate for printing presses. Each individual sensor of the measuring device is calibrated with the air of calibration strips. By means of an additional sensor of the measuring device, a printing-plate and/or printing-original-specific correction calibration and an adjustment to identical values of all sensors are provided. The correction calibration and adjustment are performed by way of a calibration field and a calibration area on the printing plate and/or printing original.
