Problems solved by technology

[0006] There are other problems in the case of distributing the image to be printed over several prints: the individual prints must be mounted in their correct arrangement and orientation in order to obtain the overall image
But this can be difficult with multiple prints, since most of the individual prints have only a small number of characteristic marks of the overall image, which in turn makes the identif

Embodiment Construction

[0034] figure 1 Shown is a print 1 with an image 3 already applied on a surface 2, an identification mark being combined with and integrated with the image 3 or integrated in the image, as an identification feature 4 is applied on the surface of the print 1 2, at the same time, based on the combination of the present invention, the identification mark 4 does not affect the displayed image of the image 3 when the printed matter 1 is viewed macroscopically. When viewing the printed image with the human eye, the identification mark 4 in the printed image cannot be recognized without the aid of an auxiliary device such as a reading device.

[0035] The term "image" below refers not only to the image to be printed, i.e. the original, but also to the image transferred to the print, the term "printed image" is used where necessary to distinguish them.

[0036] The print is preferably configured as a porcelain plate, in particular a brick, so that the image 3 to be printed is prefera...

Abstract

The invention relates to a method for printing pieces (1) with unique identifications, in particular to plate printing pieces made of natural material or synthetic material, such as plasterboards, timber, woodworks, glass, tiles and the like, which comprises an ink-jet printer (11) with an ink-jet printhead (19).The ink-jet printhead is equipped with an ink-jet nozzle (17) with at least one printing row.An image (6) to be printed is converted into the control data of the ink-jet nozzle (17) by a print data providing module (32), so that the image is transferred to the surfaces (2) of the printing pieces (1) in a point-to-point mode.An unique identification mark (30) is combined with the image (6) to be printed to form an identification feature (4) by the print data providing module (32).The identification feature is transferred onto the printing pieces (1) together with the image (6).The macroscopic characteristic of the image transferred onto the printing pieces is maintained by the combination of the identification mark (30) and the image (6).The invention also relates to a printing device for implementing the above method and the printing pieces generated by the method.

Description

technical field [0001] The present invention relates to a method for uniquely identifying prints, in particular prints of panels made of natural or synthetic substances such as plasterboard, wood, woodwork, glass, ceramic tiles and the like. Background technique [0002] The image to be transferred is broken down into print dots and transferred onto the print medium when the print is produced. For this purpose so-called inkjet printers are preferably used, in which the printing nozzles can be selectively controlled in order to eject colored ink droplets from the nozzles and transfer them to the printing medium. When preparing the print data, the image to be printed is provided such that the luminance distribution is discretized or, in the case of printing a color image, a color output is formed and likewise discretized. When viewed microscopically the printed image consists of many individual discrete printed dots which are preferably provided as densely as possible to obta...
