Abstract
The disclosure relates to a method for detecting deviations of extension of decorations on printed decorative papers, the method includes the following steps: providing the printed decorative paper on a sample table, projecting a target pattern onto the sample table and the printed decorative paper such that a distance between two predetermined pattern elements of the projected target pattern corresponds to a target distance between at least two predetermined decorative elements of the decoration, determining deviations between the actual distance of the decorative elements and the distance between the projected pattern elements.
Claims19
A method for producing decorative papers with a decoration, the method comprising:
- providing an unprinted base paper,
- printing the decoration onto the base paper,
- detecting deviations of extension of the printed decoration by
- providing the printed decorative paper on a sample table,
- projecting a target pattern onto the sample table and the printed decorative paper such that a distance between two predetermined pattern elements of a projected target pattern corresponds to a target distance between at least two predetermined decorative elements of the decoration, and
- determining deviations between an actual distance of the decorative elements and the distance between the projected pattern elements,
- wherein the projected pattern elements comprise lines, which are visible in the projection,
- determining at least one corrective measure if the detected deviation is greater than a predetermined limit value, and
- implementing the at least one corrective measure and repeating the steps in the method.
A method for processing a printed decorative paper, the method comprising:
- providing a decorative paper onto which a decoration is printed,
- detecting deviations of extension of the printed decoration
- providing the printed decorative paper on a sample table,
- projecting a target pattern onto the sample table and the printed decorative paper such that a distance between two predetermined pattern elements of a projected target pattern corresponds to a target distance between at least two predetermined decorative elements of the decoration, and
- determining deviations between an actual distance of the decorative elements and the distance between the projected pattern elements,
- wherein the projected pattern elements comprise lines, which are visible in the projection,
- processing the printed decorative paper in at least one further work step, depending on the detected deviations of extension.
