The present disclosure relates generally to signal encoding for flexographic printing plates. One aspect is a flexographic, photopolymer printing plate having transparent layers to allow encoded signal printed or laser ablated thereon to be detectable from both sides of the printing plate. Another aspect is a flexographic, photopolymer printing plate having an encoded signal formed in a photocured layer. Still another aspect is a system for tracking such printing plates, including managing location, print impression count, location tracking, etc. Other aspects are described as well.

A device for measuring elevations of a surface of a rotary body embodied as a cylinder, roller, sleeve, plate or flexographic printing plate for graphic industry machines includes a first motor for rotating the rotary body about an axis of rotation and a measuring device for contactless measurement which is part of or integrated into a mounter for printing plates. The measuring device allows the printing forme to be measured and analyzed to check mounting quality and to detect diameter differences. The measuring device preferably further includes a reference object, such as a wire tautened in an axially parallel direction, a second motor and, if desired, a further second motor for adjusting the measuring device and/or the reference object in a direction perpendicular to the axis of rotation. The device provides a fast way of measuring the elevations, such as flexographic print dots, with great accuracy.
