Abstract
A method and a device for determining color register and lateral register deviations on printing material during production in multi-color printing presses, include a computing unit which takes into consideration the influence of ghosting effects when measuring the deviations on the printing material. The ghosting effects of at least one preceding and/or one succeeding printed image are recursively taken into consideration in the computing unit, when measuring on the printing material.
Claims16
A method for determining color register and lateral register deviations on printing material during production in multi-color printing presses, the method comprising the following steps:
- taking an influence of ghosting effects into consideration in a computing unit when measuring the deviations on the printing material;
- and
- taking the ghosting effects of at least a preceding and/or a succeeding printed image recursively into consideration in the computing unit, when measuring on the printing material.
A device for measuring deviations relating to color register and/or lateral register on printing material during production in printing presses, the device comprising:
- a computing unit configured to take an influence of ghosting effects into consideration when measuring the deviations on the printing material;
- said computing unit being configured to take the ghosting effects on at least one preceding or/and on at least one succeeding printed image into consideration when determining deviations on the printing material.
