  • the invention relates to a printed product comprising a substrate and a subject printed on the substrate, a method for producing a corresponding printed product and a method for determining at least one printing parameter.
  • printing parameters are, for example, the color density, which is a measure of the color-correct reproduction of the basic colors from which the printed image, hereinafter also referred to as the subject, is printed.
  • the print quality can be assessed based on printing parameters such as the correct position of the individual printing colors in relation to one another, also known as registration, the presence of doubling, scumming, shifting or the tone value increase, etc.
  • the EN 10 2007 131 210 A1 discloses a method for detecting position markings, wherein the position markings are printed one after the other on the subject at a defined distance in the printing direction, so that the distance between the position markings can be calculated over the detected time intervals and thus the register-compliant print can be determined.
  • the EP 0 444 583 A2 discloses printing marks designed as registration marks with two intersecting lines, whereby rectilinearly delimited areas are printed in the quadrants spanned by the two lines, each of which is preceded by circularly delimited areas.
  • the EP 2 055 482 A2 discloses the registration-compliant alignment of a plurality of printing cylinders by means of linear or circular registration marks, wherein the registration marks at least partially overlap in the desired state.
  • the US$6,128,090 discloses a plurality of print marks for determining the color quality, whereby a print mark with semicircularly fanned out color elements is used, which are embedded in a rectangular area of a defined background color.
  • printing machines i.e. printing machines that print on web-like substrates
  • various printing parameters such as ink density, registration or color register inline during the printing process and to regulate compliance with the required printing parameters.
  • the printing machine Appropriate sensors are used which detect points on the printed product during ongoing production and determine the printing parameters accordingly.
  • Print control strips are known from the state of the art for determining the printing parameters on printed products taken from the printing machine as well as for recording printing parameters within the machine. These strips consist of a plurality of measuring fields arranged next to one another across the width of the printing material and thus perpendicular to the printing direction. These measuring fields usually include both solid and halftone areas of the basic colors used for printing to determine the color density or the dot gain, as well as various measuring fields for determining other printing parameters.
  • such measuring fields are arranged across the entire printing width, which usually essentially corresponds to the width of the printing material.
  • measuring fields for each printing ink are usually arranged in the area of the extension of an ink knife or ink nozzle in order to be able to control the inking zone by zone.
  • print control strips are known from the prior art which, in the direction of printing, consist only of a row of measuring fields arranged next to one another perpendicular to the direction of printing and thus in the extension of the substrate width B.
  • print control strips are also known which consist of a plurality of rows, with each row comprising measuring fields arranged next to one another.
  • the print control strips known from the prior art comprise measuring fields, in particular for determining the color density, which have dimensions of approximately three by three millimeters.
  • larger and smaller Measuring fields are known, which depends both on the sensors used and on the number of pressure parameters to be determined.
  • the print control strips known from the prior art are designed as a straight bar, which can be arranged on the leading or trailing edge of a printing form and/or a printed image or, when printing several copies in a printed product, in the middle of the printed image.
  • a straight print control strip is justified and justified in the design of the printing form, for example as a printing plate with straight curved legs, which is usually clamped in straight clamping channels on the forme cylinder, as well as in a printed product with usually straight, mostly right-angled edges such as newspapers or magazines.
  • the invention is therefore based on the object of creating a solution with which the monitoring of the print quality with a print control strip comprising a plurality of measuring fields is possible even when the edges of the subject are not straight, while at the same time optimizing the space requirement and thus the substrate requirement.
  • a print control strip according to claim 1 a printed product according to claim 6, a method for producing a printed product according to claim 7 and a method for detecting at least one printing parameter according to claim 8.
  • the print control strip according to the invention is characterized in that the area centers of gravity or the leading edges of the measuring fields of at least one row lie on an odd line, wherein the area centers of gravity or the leading edges of the measuring fields lie on an at least partially circular arc segment-shaped line or on a sinusoidal line or on a sawtooth-shaped or trapezoidal line.
  • the printed product according to the invention is characterized in that a print control strip according to the invention is printed on the printed product.
  • the method according to the invention for determining at least one printing parameter is characterized by the detection of the measuring fields contained in the print control strip according to the invention and the storage of the coordinates for each measuring field in the extension of the substrate width B and in the extension of the printing direction.
  • Such a design of a print control strip or a corresponding print product as well as the associated methods have the advantage that it is possible to determine and/or control the printing parameters by means of a print control strip even with maximum utilization of the print image and even if the print image does not follow a straight line.
  • This line can have a continuous or discontinuous course, at least in part.
  • the coordinates of each measuring field to be recorded are stored in the extent of the substrate width B and in the extent of the printing direction. For each measuring field, either the coordinates of the entire area or the coordinates of a point on the leading edge of a measuring field and/or an area center of gravity of a measuring field and/or any point within the measuring field can be stored.
  • the coordinates in the extent of the substrate width B and in the extent of the printing direction X can be retrieved for each recorded measuring field, so that on the one hand a recording of the measuring fields is ensured and also an assignment of the content of a measuring field such as the screening and the printing color is stored and can be assigned.
  • Fig.1 shows a printed product 1, which comprises a substrate 2, on which a single- or multi-colored subject 3 is printed.
  • the substrate 2 which has a product length L and a substrate width B, the substrate 2 is conveyed in the printing direction X through a printing machine (not shown) and is printed in the process.
  • the printing press is a sheet-fed printing press for printing on sheet-shaped substrate 2 or whether it is a web-fed printing press in which a web-shaped substrate 2 is printed, which is then either cut into individual sheets or rewound for further processing.
  • a print control strip 10 is usually printed on the substrate 2.
  • This print control strip 10 can, as in Fig.1 shown, be arranged on the leading edge 14 of the printed product 1. Although not in Fig.1 As shown, it is also possible to arrange the print control strip 10 in the area of the trailing edge or, in the case of multiple uses, within the subject 3.
  • Fig.2 shows the detail vein Fig.1 on an enlarged scale.
  • the print control strip 10 consists of a plurality of measuring fields 12 arranged next to one another in the extent of the substrate width B. Normally, the measuring fields 12 adjacent to one another each have a different filling, either that they are printed with a different color or that an area with a defined grid of the same or a different color is printed next to a solid color area. Further details on the design of the respective measuring fields 12 can be found in the relevant specialist literature.
  • Fig.3 also shows a section A of the print control strip 10 from the prior art in a corresponding enlargement, wherein the print control strip 10 has a plurality of rows 11 arranged one behind the other in the extension of the printing direction X, wherein each row 11 has a plurality of measuring fields 12 arranged next to one another in the extension perpendicular to the printing direction X.
  • Fig.3 shows a print control strip 10 with a first row 11-1 running in the printing direction X and a subsequent second row 11-2 of measuring fields 12.
  • Print control strips 10 with more than two rows 11 are also known from the prior art, but the number of rows 11 is not important for the present invention.
  • Fig.4 illustrates an example in which the use of a prior art straight print control strip 10 is disadvantageous. While in subjects 3 with straight and especially rectangular contours, as for example in Fig.1 shown, the insertion of a print control strip 10 only leads to a relatively small additional space requirement and thus to a relatively small additional requirement for substrate 2, this results in subjects 3 with non-rectilinear contours, such as in Fig.4 As shown, a straight print control strip 10 leads to an increased substrate consumption due to the large proportion of unprinted and thus unusable area.
  • the subjects 3 shown as examples are used, for example, in packaging printing, where the subject 3 comprises panels 4 of any shape and preferably arranged in an optimized manner with respect to the space required.
  • Such panels 4 can have any shape, such as a circular shape, so that with a correspondingly optimized arrangement the subject 3 has a non-rectilinear contour.
  • Fig.5 shows that in Fig.4 already shown subject 3, which has a non-rectilinear contour due to the shape of the panels 4 and/or the arrangement of the panels 4.
  • the distance between the print control strip 10 and the subject 3 can be kept uniformly small across the entire width of the subject 3 or across the entire substrate width B.
  • the distance between the non-linear print control strip 10 and the trailing contour of the subject 3 as seen in the printing direction X can also be kept small, so that when the subject 3 including the print control strip 10 is arranged around the outer surface of a forme cylinder, only a minimal additional space is required and the leading and trailing edges of the entire printed image can be joined together without gaps.
  • Fig.6 shows that in Fig.5
  • the subject 3 shown is wound around the outer surface of a forme cylinder.
  • a print control strip 10 according to the invention, it is possible to arrange a large number of copies 4 including a print control strip 10 on the outer surface of a forme cylinder with a minimal unprinted and thus unusable area of the substrate 2.
  • the forme cylinder is an engraved gravure cylinder or a forme cylinder with a clamped printing form, as is used for example in flexo or offset printing processes.
  • the printing forme attached to the forme cylinder can also have edges adapted to the contour of the subject 3 so that as many panels 4 as possible can be arranged on the outer surface without excessive loss of space.
  • Fig.7 shows a detailed view of the Fig.5 shown print control strip 10 in a configuration with a row 11 and square measuring fields 12, whereby according to Fig.5 the print control strip 10 extends at least over part of the substrate width B.
  • the print control strip 10 is printed on the substrate 2 with all the printing inks in use and thus with at least one printing ink.
  • the print control strip 10 comprises, in the extension of the printing direction X, a row 11 of measuring fields 12 arranged next to one another perpendicular to the printing direction X, wherein in the section B according to Fig.7 only the measuring fields 12-1 to 12-14 are shown.
  • Each measuring field 12 has a center of gravity 13-1 to 13-14 and an edge 14 extending in the direction of printing X, in which Fig.7
  • Fig.7 For the sake of clarity, only the reference edges of the leading edges 14-2, 14-8 and 14-12 are provided with reference symbols. However, it goes without saying that all of the Fig.7
  • the measuring fields 12-1 to 12-14 shown have a leading edge 14.
  • Each measuring field 12 also includes a center of gravity 13.
  • the area centroid 13-2 of the measuring field 12-2 is offset by the offset ⁇ x in the printing direction X from the area centroid 13-1 of the measuring field 12-1.
  • the area centroids 13 arranged next to one another perpendicular to the printing direction X also have an offset ⁇ x in or against the printing direction X, with the exception of the measuring fields 12-7 and 12-8.
  • the area centroids 13-1 to 13-14 are thus located on an odd line 15, which in the Fig.7 example shown has a substantially sinusoidal shape.
  • the Fig.7 shown line 15 and thus essentially the one in Fig.5 shown print control strip 10 by way of example due to the Fig.5
  • the line 15 it is also possible for the line 15 to at least partially assume any desired shape, such as, for example, a circular arc segment-shaped, a sawtooth-shaped or a trapezoid-shaped line 15.
  • the line 15 on which the area centers of gravity 13 or the leading edges 14 of the measuring fields 12 of at least one row 11 lie can at least partially have a continuous course and/or partially have an unsteady course.
  • the course of the line 15 and thus essentially the contour of the print control strip 10 is essentially dependent on the shape of the panels 4 and thus on the contour of the subject 3 as a whole of the panels 4, so that abrupt unsteady courses are also possible for maximum space optimization.
  • the measuring fields 12 shown in Fig.7 shown measuring fields 12-1 to 12-7 and 12-8 to 12-14 the respective leading edge 14 arranged offset in or against the printing direction X relative to the leading edge 14 of the measuring field 12 adjacent perpendicular to the printing direction X.
  • the leading edge 14-13 of the measuring field 12-13 also has the offset ⁇ x in the printing direction X to the leading edge 14-14 of the measuring field 12-14 in relation to an imaginary line between the measuring fields 12-7 and 12-8.
  • Fig.8 shows section B from Fig.5 , albeit for a print control strip 10 with a plurality of rows 11, namely a first row 11-1 and a second row 11-2.

  • the print control strip 10 shown has exemplary round measuring fields 12.
  • the remaining measuring fields 12 have an offset ⁇ x in the printing direction X to the respective adjacent measuring field 12 in relation to the respective area centers of gravity 13. Due to the circular shape of the measuring fields 12, the leading edge 14 as a whole is therefore not a preferred reference for the offset ⁇ x to the leading edge 14 of the respective adjacent measuring field 12, since this requires the definition of a specific point is required. In this embodiment, the centroid 13 of a respective measuring field 12 is therefore suitable as a reference value for the offset ⁇ x.
  • Fig.10 shows a further possible embodiment of a print control strip 10 according to the invention.
  • Fig.10 also shows section B from Fig.5 .
  • Fig.10 shows a design of the measuring fields 12, in which the respective measuring fields 12 have the same measuring field width b perpendicular to the printing direction X and thus parallel to the substrate width B, but in which each measuring field 12 has an odd and measuring field-specific leading edge 14.
  • the leading edge 14 of each measuring field 12 is thus a section of the contour of the print control strip 10, which is preferably adapted to the subject 3.
  • the measuring field height h is in the Fig.10 In the example shown, the values are identical for each measuring field 12, but this does not necessarily have to be the case.
  • the leading edge 14 is a poor reference point for defining the offset ⁇ x, but this offset ⁇ x from one measuring field 12 to the adjacent measuring field 12 can be achieved via the respective area centers of gravity 13.
  • the offset ⁇ x in the pressure direction X between the centroid 13-1 of the measuring field 12-1 and the centroid 13-2 of the measuring field 12-2 is shown as an example.
