Abstract: Provided is a method for producing at least one carrier material provided with a print decoration. The print decoration is applied to the at least one carrier material by means of digital printing. The water-soluble CRYK ink used for the digital printing has the following composition: Colour component C: at least one cyan pigment; Colour component K: at least one black carbon pigment; Colour component Y: at least one yellow pigment; or a mixture of at least two different yellow pigments or a mixture of at least one yellow pigment and at least one red pigment; and Colour component R: at least one red pigment, or a mixture of at least two different red pigments or a mixture of at least one red pigment and at least one yellow pigment.

Abstract: The disclosure relates to a method for printing a paper web with at least one print motif by means of a digital printing facility. The method includes: providing a digital image of a master sample of the print motif, printing a plurality of copies of a section of the at least one print motif with different color settings, creating digital images of the printed copies, comparing the digital images of the printed copies with the digital image of the master sample, where a degree of similarity is determined in each case, selecting color settings using the determined degrees of similarity and printing the print motif onto the paper web with the selected color settings.

Abstract: The invention relates to a method for adapting the printer parameters of a digital printer. A tone value target with 1 to n tone value fields, where n?N, is output onto a carrier material, and at least some of the tone value fields are measured in a hyperspectral manner. A digital reference pattern is generated from the measurement data. The tone value target is output onto a second carrier material, and at least some of the tone value fields are then measured in a hyperspectral manner. A digital pattern is generated from the measurement data, said digital pattern being compared with the digital reference pattern. At least one similarity value is ascertained, and if the similarity value lies outside of a specified tolerance range, at least one printer parameter or a combination of multiple printer parameters are adapted. The invention additionally relates to a device for carrying out the method according to the invention.

Abstract: A film composite with protection against tampering includes a base film, which is arranged as the lowermost layer in the film composite, and a cover layer, which is arranged as the uppermost layer in the film composite. The film composite further includes an intermediate film, which is arranged between the base film and the cover layer, and a laser-inscribable layer, which is arranged in the film composite between the base film and the intermediate film. Lines of weakening are provided in the film composite, which run within the base film and within the intermediate film.

Abstract: The present invention relates to a process for comparing a reference colour profile or the color space value of the reference color profile of an analogue reference pattern with a decorative-element-specific color profile or the color space value of the decorative-element-specific color profile of a digital or analogue decorative element. In the course of the process, a reference color profile is created by reading in and storing measurement data of at least one portion of an analogue reference pattern by means of a hyperspectral area measuring device. According to the invention, a decorative-element-specific color profile is created either from the digital data of a digital decorative element or using hyperspectral area measurement of at least one portion of an analogue decorative element.
