Method for verifying a printing plate, specifically a gravure cylinder
Abstract:
The invention relates to a method for verifying a printing plate, specifically a gravure cylinder, for errors in an engraving of the printing plate, comprising the following steps: Generating at least two proofs using a printing plate to be verified, capturing at least one digital image each of the at least two proofs with an image-capturing unit, comparing each of the digital images of the at least two proofs with the engraving template of the printing plate, wherein the comparison comprises the following steps: Detecting deviations between each of the images and the engraving template, and verifying that the detected deviations occur in identical fashion on the digital images of all of the at least two proofs, wherein a pseudo error is indicated if the comparison does not show identical deviations between the digital images of the at least two proofs, and wherein identical deviations indicate an engraving defect in the printing plate.
