Definitions

  • the invention relates to a method for multicolored inkjet printing on containers according to the preamble of claim 1, as is known from U.S. 2013/176358 A1 and EP 1 769 916 , as well as a corresponding device.
  • the labeling of containers in bottling plants or the like is increasingly carried out by means of ink jet printing directly on the container due to the flexibility in terms of design and the adaptation to different products.
  • the containers are moved along stationary print heads during direct printing, and in which the transport speed of the containers relative to the print heads is temporarily reduced during printing in order to enable high average transport speeds and machine outputs.
  • the DE 10 2012 213 080 A1 known to distribute the incoming stream of containers in parallel to several printing units in order to increase overall machine performance.
  • the DE 10 2010 020 958 A1 proposed to move printing stations on a track parallel to the means of transport of the containers.
  • the DE 10 2014 116 201 A1 propose to print test containers or the like in a first printing station with a test pattern, to inspect this and to adjust a subsequent printing station on the basis of the inspection result.
  • separate test containers must be provided for this and introduced into the machine.
  • this is used for multicolored inkjet printing on containers and comprises the following steps: S1) joint printing of a motif or a first motif layer and at least one print mark arranged in particular within the motif in a first printing color on the containers; S2) mechanical optical inspection of the at least one print mark; S3) aligning the containers based on step S2 and printing the motif or a second motif layer, and in particular the print mark, in a subsequent printing color; and S4) overprinting of the print mark.
  • the print quality for each printing color or motif layer can be optimized during regular printing operations with regard to the printing colors already printed.
  • the print mark enables a simplified inspection of the print quality compared to the motif and/or features of the container, for example with regard to the position of the motif and with regard to the quality of individual printing colors.
  • the print mark can be concealed by the overprinting in the final printed image and thus the appearance of the finished printed container can be optimized.
  • Print marks within the meaning of the present invention are in particular registration marks for checking the location/position of the motif printed with a specific printing ink or a specific motif layer and color marks for checking the uniformity of the print quality of a specific printing ink or motif layer. Also conceivable are print marks that have the function of registration marks as well as color marks. In principle, the print marks could also be arranged outside of the motif, for example above and/or below the motif.
  • the motif is a printed image which, based on a digital print template, is printed step by step in the form of several motif layers directly onto the containers using an ink jet.
  • the motif layers have inks of a specific color model such as CMYK.
  • An initial motif layer may be the background color of the motif, specifically white. The background can be part of the printed motif or the printed container.
  • Steps S2 and S3 are preferably carried out on the condition that there is a fixed spatial relationship between the inspection units and print heads used for this purpose, in the sense that the position of the print mark determined in step S2 corresponds to a specific rotational position of the containers and specific active nozzles of the print head to be used can be assigned, particularly within a certain vertical working range of the print head.
  • steps S2 and S3 are repeated in pairs for at least two further subsequent printing colors.
  • the print quality can also be optimized for the other subsequent printing colors directly and in the sense of an inspection loop that is closed separately for each subsequent printing color.
  • active printing nozzles are selected in step S3 based on the inspection of step S2. It would also be conceivable to select the print time for individual print nozzles and/or for the print head as a whole depending on the inspection of step S2. With the selection of active print nozzles, a vertical print area for the subsequent motif layer can be defined within a total vertical working area available on the print head.
  • a vertical area of an assigned print head that is active in step S3 is shifted vertically by targeted activation of print nozzles in order to cover a vertical print area required for the motif.
  • the vertical working area of the print head is then higher than the motif. This enables a vertical adjustment of the motif layer to be applied with the respective subsequent ink.
  • a vertical adjustment of the print head would also be conceivable.
  • the horizontal position of the motif layer to be applied with the subsequent printing ink can be adjusted and/or corrected, taking into account a relative transport movement between the container and the print head.
  • the rotational position of the containers is preferably adjusted in step S3 based on the inspection in step S2 for the printing of the motif in the respective subsequent printing color.
  • step S4 is finally executed after step S3 has been executed for the last time.
  • the direct printing with all printing inks of the color model can be controlled separately for each motif layer using the print mark before the print mark is made unrecognizable by overprinting in step S4.
  • Step S4 is preferably carried out in a separate correction station for multi-color printing.
  • the print mark can be made unrecognizable in step S4, for example, in that the print mark is multicolored overprinted with a component of the motif. It is also conceivable to make the print mark unrecognizable by overprinting it outside of the motif with a color and/or a pattern that is present on the container in the area around the print mark.
  • the first printing ink is preferably white and is excited to fluoresce in particular in step S2 with UV light.
  • White is suitable as a background color for a brilliant multi-page motif. Fluorescence can be used to achieve improved contrast for the inspection of the print mark, especially compared to a light-colored or white container wall.
  • the print mark is then omitted from the print in step S3. It is possible to only print the print mark when printing with the background color white and to align the direct print with all subsequent print colors of the color model using the print mark printed with the background color.
  • the print mark would then only be overprinted in step S4, in particular with black printing ink, blue printing ink, red printing ink or a mixed color. In other words, this variant is particularly suitable if the print mark is in a dark area of the motif. The absence of the background color white in the area of the print mark is then not noticeable in the finished printed motif.
  • the containers are excited to fluoresce in step S2 with UV light.
  • Transparent (opaque) white plastic containers or translucent (translucent) white plastic containers that fluoresce when exposed to UV light are particularly suitable for this purpose.
  • the first printing color in particular a white background color, is then essentially non-fluorescent.
  • a particularly white pressure mark can be compared to the unprinted container wall locate dark contrast in step S2.
  • the print mark is then preferably opaque.
  • the print mark is preferably printed within the motif and, in step S4, overprinted with a partial area of the motif, in particular in multiple colors.
  • the print mark is printed outside of the motif and, in step S4, overprinted with the color and/or a pattern of the container wall surrounding the print mark.
  • the print mark preferably includes a registration mark, with rotary mounts for the containers and/or print head nozzles for printing with the subsequent printing ink also being controlled as a function of a determined position of the registration mark. This allows the rotational position of the container to be corrected for the subsequent printing ink.
  • a specific, in particular vertical, area of the print head can be specifically activated for printing with the subsequent printing ink in order to align the motif to be printed with it precisely in relation to the motifs previously printed with other printing inks.
  • the print mark comprises a color mark, with the printing of the same container with the subsequent printing ink being released or suppressed depending on a determined print quality of the color mark, and/or the printing of subsequent containers with the same printing color being corrected depending on a determined print quality of the color mark .
  • the color mark is, for example, a field with a uniform color tint or a predetermined color tint gradient. Deviations from this can be recognized as printing errors in step S2 in order to specifically trigger actions for the further treatment of the same container and/or to correct the print with the printing ink recognized as defective for subsequent containers.
  • a correction for subsequent containers is possible, for example, by replacing or compensating for pressure nozzles identified as defective by at least one adjacent pressure nozzle.
  • multicolor printing takes place at half the resolution of the respective print head, ie using every second print nozzle. If a specific printing nozzle fails, it can be replaced, for example, by the immediately adjacent printing nozzle or by an adjacent group of printing nozzles.
  • the suppressed pressure containers are selectively discarded.
  • the containers identified as faulty are then preferably no longer printed with the subsequent printing inks or the correction print for the printing mark in order to save printing ink.
  • Defective containers are preferably rejected automatically downstream of the device used for multicolor printing.
  • the motif is preferably composed of partial circumferential print areas and at least one print mark is printed on each print area.
  • the individual partial circumferential print areas can then be aligned and checked separately on their respectively assigned print mark. This compensates for inaccuracies when repositioning the containers for printing on the individual print areas. All print marks are then overprinted in step S4.
  • this is used for multicolored inkjet printing on containers and comprises: several consecutive color stations each with at least one print head for printing the containers in an assigned printing color and with a subsequent inspection unit for optically inspecting the printed motif and/or at least one print mark printed in the color stations by stimulation the container (12) with UV light for fluorescence; a correction station which follows the color stations and has at least one print head for selectively overprinting the print mark; a transport means with rotating supports for successively positioning the containers in the color stations and in the correction station; and a control unit for driving the rotating posts and the print heads depending on results from the inspection units.
  • the inspection unit is preferably designed in such a way that it spatially selectively inspects the print marks in contrast to a complete inspection of the entire motif.
  • the inspection unit is then particularly capable of fault detection based on an imaging detection of contrast gradients and/or color gradients in the print marks is based, in particular by means of targeted evaluation of the previously applied printing ink.
  • evaluation algorithms then run in the inspection unit, which are designed specifically for determining the position of registration marks and for evaluating color gradients or brightness gradients in color marks.
  • the print heads are preferably designed in such a way that they continuously cover at least the entire height of the motif to be printed. In principle, however, it would also be conceivable to arrange a plurality of print heads so that they overlap in the vertical direction in order to cover the entire height of the motif.
  • the print heads preferably have a resolution of at least 1200 dpi.
  • the rotary mounts comprise servomotors and the maximum print height of the printheads is greater than the height of the motif. This will provide an exact correction of the situation motifs to be printed with a specific ink, both vertically and horizontally.
  • the inspection units preferably include cameras for imaging the containers all around.
  • a plurality of cameras can be present at least in the entry-side inspection unit in order to inspect the containers with a plurality of partial-circumference camera images over the entire circumference without any gaps. This allows the entire area of the motif to be printed and the printed print mark to be monitored and the quality of the print to be determined on the basis of the print mark. This configuration could also be used on the subsequent inspection units.
  • the subsequent inspection units could inspect only the partial peripheral area of the container in which the print mark was printed and initially recognized. It would also be conceivable to carry out a rough alignment of the rotational position before printing with the first printing ink, so that only the partially circumferential printing area with the printing mark to be inspected then has to be examined.
  • a rough alignment of the rotational position would be possible, for example, using container contours, such as embossing. Since the rotational position of the container is then fundamentally known on the basis of such an incoming inspection of the container and/or can be corrected accordingly, only a comparatively small correction of the rotational position is necessary during the subsequent inspection and correction of the rotational position using the print marks in order to avoid deviations during positioning and Transporting the containers in the individual color stations or to compensate in between.
  • an optical sensor possibly also non-imaging, could be present directly in front of each color station, which localizes the print mark comprising a registration mark and causes the immediately following color station and/or the rotary table assigned to the container to correct the subsequent imprint by means of the control unit.
  • the figure 1 shows schematically an intermediate stage during the multicolor inkjet printing of a motif 1. Seen in the printing direction DR, this is preferably composed of several motif parts 1A-1D, which are printed one after the other with a specific printing ink after the rotational position of a container to be printed with respect to a print head.
  • the motif 1 is applied in succession in the form of motif layers with the individual printing inks, as is explained below by way of example.
  • the motif parts 1A-1D are preferably separately assigned internal print marks 2A-2D including registration marks and internal print marks 3A to 3D including color marks. Register marks and color marks can also be combined in print marks (not shown).
  • the figure 1 shows a state after printing a first motif layer MS1 in a first ink DF1, which is a white background color in the example shown, and a second motif layer MS2 in a second ink DF2, which is any component of a color model used, such as CMYK.
  • the print marks 2A-2D and 3A-3D have the second print color DF2.
  • an external printed mark 2E comprising a register mark and an external printed mark 3E comprising a color mark, each outside the motif 1 in the area of a surrounding container wall 4 of a wall color WF, indicated schematically.
  • the external print marks 2E, 3E can be printed in addition to or as an alternative to internal print marks 2A-2D and 3A-3D, preferably above and/or below the motif 1 and have the second printing color DF2 in the example.
  • the dimensions of the motif 1 are defined by a vertical motif area YM in the sense of a motif height and by a horizontal motif area XM, which is shown as an example as the developed length of the entire motif 1 .
  • the horizontal motif area XM results from the uninterrupted juxtaposition of motif parts 1A-1D.
  • FIG. 12 also schematically shows a print head 5 for single-color printing with a subsequent printing color DF3 of the color model used.
  • the print head 5 has, for example, two rows of nozzles 6 and 7, which together cover a vertical working area YMAX that is larger than the vertical motif area YM.
  • the vertical alignment of the motif layers MF1, MF2 of the motif 1 that have already been printed with respect to the print head 5 is determined on the basis of the print marks 2A to 2D and/or 2E. Depending on this, only those printing nozzles 8 of the print head 5 are used for printing with the following Printing ink DF3 activated, which cover the currently determined vertical motif area YM.
  • the vertical area YA of the print head 5 that is required for the subsequent print and is thereby selectively active can thus be shifted up or down within the vertical working area YMAX by targeted nozzle activation.
  • This enables the subsequent motif layer MS3 to be printed congruently in the printing ink DF3 on the previously printed motif layers MF1 and MF2.
  • the common reference for this is a (not shown) digital color master for motif 1.
  • the print head 5 has two vertical rows of nozzles 6 and 7 which are offset from one another at a vertical distance YD.
  • nozzles 6 and 7 which are offset from one another at a vertical distance YD.
  • the rows of nozzles 6, 7 can, for example, be controlled in a known manner with a time offset adapted to the horizontal distance XA between the rows of nozzles 6, 7 in order to align all print dots in a specific column of the print template vertically with one another.
  • the print head 5 is actuated as a function of the position of the print marks 2A-2D and/or 2E, which is determined in particular by imaging. These have a known spatial relationship to motif 1 in each motif layer and serve as registration marks for determining the relative position, here by way of example of the last printed motif layer MF2 with respect to print head 5 for printing with the subsequent printing ink DF3. However, non-imaging scanning of the print marks 2A-2D and/or 2E would also be conceivable.
  • the multi-color printing of motif 1 takes place successively during a particularly continuous transport movement 10 of the container to be printed along several preferably stationary print heads 5.
  • the printing direction DR results from the superimposition of transport movement 10 with a targeted change in rotational position of the associated container and its container wall 4 in front of the respective print head 5.
  • the print head 5 immediately afterwards prints both the motif 1 and new print marks 2A-2D, 3A-3D, 2E and/or 3E in the next printing color DF3.
  • Separate rows of nozzles or pairs of rows of nozzles 6, 7, which can be part of a common print head 5 or separate print heads 5, are assigned to the partially circumferential motif parts 1A-1D.
  • the position of the respective motif part 1A-1D in the printing direction DR and the targeted selection of active printing nozzles 8 are then preferably carried out separately using the respectively assigned printing mark 2A-2D.
  • the number of partially circumferential motif parts 1A-1D and the rows of nozzles 6, 7 per printing color depends, for example, on the length of the motif 1 and/or the machine output and can be adapted to the respective requirements. For the sake of simplicity, a single print head 5 per printing color is always mentioned below.
  • the figure 2 shows a schematic plan view of a device 11 for multicolor printing on containers 12 with a plurality of stationary consecutive color stations 13-17 and a subsequent correction station 18.

  • a pinning unit 21 is preferably connected in between in order to intermediately cure the ink printed immediately beforehand by means of UV light.
  • the color stations 13-17 are constructed identically in this respect and differ only in that they are used to print different printing colors DF1 to DF5 of a color model, such as CMYK, onto the containers 12.
  • the correction station 18 is preferably designed with a print head 22 for multicolor printing for overprinting the print marks 2A-2E and/or 3A-3E.
  • the containers 12 circulate on a container table 23, which in particular can be continuously rotated about itself, which results in the transport movement 10.
  • the container table 23 is a partial circle with rotary mounts 24, such as turntable, for the container 12 schematically in FIG figure 2 implied.
  • the transport movement 10 and one Cyclic rotation 25 of the rotary mounts 24 about themselves result in a cyclic advance of the container wall 4 with respect to the print head 5 in the printing direction DR.
  • Device 11 also includes components known per se, such as an infeed starwheel 26, an outfeed starwheel 27, an inlet-side inspection unit 28 for detecting the rotational position of incoming containers 12, an outlet-side inspection unit 29 for final inspection of the finished printed containers 12, and a control unit 30. This is for selective Activation of the printing nozzles 8, 8a and for the selective and individual activation of the rotary mounts 24, which are preferably driven by servomotors.
  • a mechanical assembly block would also be possible on device 11 with at least one upstream unit for container pretreatment, for example for flame treatment, corona treatment and/or plasma treatment of the container, and/or with at least one downstream unit for container final treatment, for example for final coating, painting and/or UV irradiation of the containers.
