Abstract

In some examples, a print control strip includes at least one control patch configured as an element for color management. The element for color management may be configured to measure a color density and/or at least one spectral value and/or an area of coverage of individual printed printing colors. The print control strip further includes at least one control patch configured as a printing mark. The printing mark is configured for aligning a substrate in a transport direction and/or in a transverse direction. Additionally, the print control strip includes at least one control patch configured as a plate recognition patch. The plate recognition patch is configured to assign at least one printing color used to a printing plate and/or to an application mechanism and/or is configured for such assignment.

First claim

The invention claimed is:

1. A print control strip comprising:
at least eight control patches arranged in a row and abutting one another in at least one print control strip, the at least eight control patches in the at least one print control strip having a same height and a same width,
the at least one print control strip including at least one of the control patches configured as an element for color management, each at least one element for color management including a single printing ink embodied as a solid color patch or as a screen dot patch of the single printing ink, the at least one element for color management being configured to enable measurement of a color density and/or at least one spectral value and/or an area coverage of individual printed printing colors of printing inks,
the at least one print control strip including at least two of the control patches configured as at least two printing marks, respectively, wherein at least one control patch having a different function is arranged between the at least two printing marks, the at least two printing marks being configured to enable alignment of at least one substrate in a transport direction and/or in a transverse direction, each of the at least two printing marks being configured as at least one of a bar, a cross, a rectangle, or a polygon, and having at least one straight edge, wherein at least one of the printing marks is surrounded by at least one of an unprinted region or unicolor region,
the at least one print control strip including at least one of the control patches configured as a plate recognition patch, the at least one plate recognition patch including at least two elements for plate recognition, wherein each element of the at least two elements for plate recognition is assigned to one printing color of at least two different printing colors, respectively, and each element for plate recognition is printed by the one printing color assigned thereto, wherein the printing color assigned to a respective element for plate recognition of the at least two elements for plate recognition is assigned to a respective printing plate that generated the respective element for plate recognition, wherein the at least two elements for plate recognition are configured as forms that differ from one another, the forms including digits that differ from one another, letters that differ from one another, or a mixture of digits and letters that differ from one another, and wherein the at least one print control strip includes as many of the elements for plate recognition as there are printing inks used for printing the at least one substrate, and
the at least one print control strip including at least one of the control patches configured as a side recognition mark, the at least one side recognition mark configured to indicate a surface of the at least one substrate on which the at least one print control strip is situated or is to be situated, wherein the at least one side recognition mark has an optical pattern that differs from optical patterns of other control patches having different functions and is configured to include at least one geometric figure.

2. The print control strip according to claim 1 , wherein at least one of:
the at least one print control strip includes at least one of the control patches configured as a print register element,
the at least one print control strip includes at least one of the control patches configured as an information mark, or
the at least one print control strip includes at least one of the control patches configured as a reference patch.

3. The print control strip according to claim 1 , wherein:
the at least one printing mark has a geometry that can be generated by at least one of a digital printing method and/or cold foil method and/or hot foil method and/or flexographic printing method and/or gravure printing method and/or offset printing method, and/or
the at least one printing mark is configured such that the position of the at least one substrate including the at least one print control strip in the transport direction and/or in the transverse direction is determined by the at least one printing mark.

4. The print control strip according to claim 1 wherein the at least two printing marks are arranged symmetrically with respect to an axis of symmetry of the at least one print control strip.

5. The print control strip according to claim 2 , wherein at least one of:
the at least one information mark is configured as a code,
the at least one information mark includes job data,
the at least one information mark includes reference values of the control patches of the at least one print control strip,
the at least one information mark includes information regarding arrangement rules,
the at least one print register element is configured to monitor a color register and/or a perfecting register,
the at least one print register element comprises at least two register elements,
the at least one reference patch has a color density of zero percent and/or a tonal value of zero percent,
the at least one reference patch is unprinted, or the at least one reference patch is configured to enable setting and/or adjustment of at least one sensor of at least one sensor device.

6. A substrate, characterized in that the substrate includes the at least one print control strip according to claim 1 .

7. The substrate according to claim 6 , wherein at least one of:
the at least one print control strip is positioned in a region outside at least one print image of the substrate,
the at least one print control strip is integrated into at least one print image of the substrate, or
the substrate comprises at least one multiple-up and at least one offcut piece, and the at least one print control strip is positioned and/or is to be positioned on the at least one offcut piece.

8. A method comprising:
controlling by open-loop control and/or closed-loop control at least one component of a processing machine, at least one infeed unit of the processing machine comprising at least one sensor device, the at least one sensor device comprising at least two sensors, the at least one sensor device detecting at least one printing mark integrated into at least one print control strip of at least one substrate, the at least one substrate being adjusted in a transport direction and/or transverse direction as a function of the detecting by the at least one sensor device, wherein:
the at least one print control strip includes at least one control patch configured as a plate recognition patch,
the at least one plate recognition patch includes at least two elements for plate recognition, wherein each element of the at least two elements for plate recognition is assigned to one printing color of at least two different printing colors, respectively, and each element for plate recognition is printed by the one printing color assigned thereto,
the printing color assigned to a respective element for plate recognition of the at least two elements for plate recognition is assigned to a respective printing plate that generated the respective element for plate recognition,
the at least two elements for plate recognition are configured as forms that differ from one another, the forms including digits that differ from one another, letters that differ from one another, or a mixture of digits and letters that differ from one another,
