Abstract
A method for registering a press machine including printing stations, each including a plate roller with a printing plate. Each printing plate includes a microdot engraving. The method includes displacing the plate rollers with respect to each other for scattering them, printing a scattered microdot pattern on a print substrate, acquiring an image of the scattered microdot pattern, associating the plate rollers with their respective microdot marks, and displacing the plate rollers to a registered position, Each of the plate rollers is associated with a unique scattered displacement and with its respective microdot mark according to the position of its respective microdot mark relative to the other microdot marks in the scattered microdot pattern, and to the unique scattered displacement of the plate roller. The plate rollers are displaced to a registered position according to the position of their respective microdot marks relative to the other microdot marks.
