Definitions

  • the invention relates to a method and apparatus for multicolor inkjet printing on containers.
  • DE 10 2014 109 948 A1 and DE 10 201 1 009 393 A1 disclose methods and devices in which the containers are moved along stationary printing heads during direct printing, and in which the transport speed of the containers with respect to the Printheads are temporarily reduced during printing to enable high average transport speeds and machine performance. Furthermore, it is known from DE 10 2012 213 080 A1 to distribute the incoming container flow in parallel to a plurality of printing units in order to increase overall machine performance. Alternatively, DE 10 2010 020 958 A1 proposes to move printing stations on a web parallel to the means of transport of the containers.
  • DE 10 2014 116 201 A1 proposes to print test containers or the like in a first printing station with a test pattern, to inspect this and to set a subsequent printing station on the basis of the inspection result.
  • this separate test containers must be provided and introduced into the machine.
  • this is used for multi-color inkjet printing on containers and comprises the following steps: S1) common printing of a motif or a first motif layer and at least one especially arranged within the motif print mark in a first ink on the container; S2) automated optical inspection of the at least one print mark; S3) aligning the containers based on the step S2 and printing the motif or a second motif layer, and in particular the print mark, in a subsequent ink; and S4) overprinting the print mark.
  • the print quality for each printing ink or motif layer can be optimized during the regular printing operation with respect to the already printed printing inks.
  • the print mark in this case allows a simplified compared to the subject and / or characteristics of the container inspection of the print quality, for example, in terms of the location of the subject and the quality of individual inks.
  • the print mark can be laminated by the overprinting in the final printed image and thus the appearance of the finished printed container can be optimized.
  • Printing marks within the meaning of the present invention are, in particular, registration marks for checking the position / position of the motif printed with a specific printing ink or a specific motif layer and color marks for checking the uniformity of the printing quality of a particular printing ink or motif layer. Also conceivable are print marks, which have both the function of registration marks and color marks. The print marks could in principle also be arranged outside the motif, for example above and / or below the motif.
  • the motif is a printed image, which is printed on the basis of a digital print template step by step in the form of multiple motifs directly on the container by means of inkjet.
  • the motif layers have inks of a particular color model such as CMYK.
  • An initial motif layer may have the background color of the subject, in particular White. The background may be part of the printed motif or the printed container.
  • Steps S2 and S3 are preferably based on the assumption that there is a fixed local relationship between the inspection units and printheads used in the sense that the position of the print mark determined in step S2 corresponds to a specific rotational position of the containers and certain active nozzles of the printhead to be used can be assigned, in particular within a certain vertical working range of the print head.
  • the steps S2 and S3 are repeated in pairs for at least two further subsequent printing inks.
  • the print quality can also be optimized directly and in the sense of a separately closed inspection loop for each subsequent ink.
  • step S3 active pressure nozzles are selected based on the inspection of step S2. It would also be conceivable to select the printing time for individual printing nozzles and / or for the printing head as a whole as a function of the inspection of step S2. Selecting active print nozzles allows you to specify a vertical print area for the subsequent motif layer within a vertical workspace that is available on the printhead.
  • a vertical area of an associated printhead active in step S3 is vertically displaced by selective activation of printing nozzles to cover a vertical printing area required for the subject.
  • the vertical working area of the printhead is then higher than the subject. This allows vertical adaptation of the motif layer to be applied with the respective subsequent printing ink. Conceivable, however, would also be a vertical adjustment of the print head.
  • the horizontal position of the motif layer to be applied with the succeeding ink can be adjusted and / or corrected in consideration of a relative transportation movement between the container and the print head.
  • the rotational position of the containers is adjusted in step S3 based on the inspection in step S2 for the printing of the motif in the respective subsequent printing ink.
  • step S4 is finally executed after last execution of step S3.
  • step S4 the direct printing with all the inks of the color model based the print mark for each motif layer are checked separately before the print mark is made unrecognizable by overprinting in step S4.
  • Step S4 is preferably performed in a separate correction station for the multicolor printing.
  • the print mark can be made unrecognizable in step S4, for example, by overprinting the print mark with a component of the motif in multiple colors. It is also conceivable to make the print mark unrecognizable by overprinting it outside the motif with a color and / or a pattern which is present on the container in the region around the print mark.
  • the first printing ink is preferably white and is excited to fluoresce with UV light, in particular in step S2.
  • White is suitable as a background color for a brilliant multipurpose printed motif. Fluorescence makes it possible to achieve an improved contrast for the inspection of the printed mark, in particular with respect to a light or white container wall.
  • the print mark is then recessed by the pressure in step S3. It is possible to print the print mark only when printing with the background color white and align the direct print with all subsequent inks of the color model on the basis of printed with the background color print mark.
  • the print mark would then be overprinted only in step S4, in particular with black printing ink, blue printing ink, red printing ink or a mixed ink.
  • this variant is particularly suitable when the print mark lies in a dark area of the subject. The absence of the background color white in the area of the print mark is then not disturbing in the finished printed motif.
  • the containers are excited to fluoresce with UV light in step S2.
  • Transparent (opaque) white plastic containers or translucent (translucent) white plastic containers which fluoresce due to their production when irradiated with UV light, are particularly suitable for this purpose.
  • the first printing ink in particular a white background ink, is then substantially non-fluorescent. This makes it possible to localize a particularly white print mark with respect to the unprinted container wall as a dark contrast in step S2.
  • the print mark is then preferably opaque.
  • the print mark is printed within the motif and overprinted in step S4 with a partial area of the motif, in particular multicolored.
  • the print mark is printed outside the motif and overprinted in step S4 with the color and / or a pattern of the container wall surrounding the print mark. This allows the print mark irrespective of their position on the container with respect to the final appearance of the container.
  • the print mark comprises a registration mark, with further rotation holders for the containers and / or print head nozzles being actuated for printing with the subsequent printing ink as a function of a determined position of the registration mark.
  • This makes it possible to correct the rotational position of the container for the subsequent printing ink.
  • it is possible to selectively activate a particular vertical area of the print head for printing with the subsequent printing ink in order to align the motif to be imprinted precisely with respect to the motifs previously printed with other printing colors.
  • the print mark preferably comprises a color mark, wherein the printing of the same container with the subsequent printing ink is enabled or suppressed in dependence on a determined print quality of the color mark, and / or wherein the printing of subsequent containers with the same printing ink is corrected in dependence on a determined print quality of the color mark ,
  • the color mark is, for example, a field with a uniform hue or a predetermined hue progression. Deviations from this can be detected as printing errors in step S2 in order to initiate targeted actions for the further treatment of the same container and / or to correct the pressure with the ink identified as defective for subsequent containers.
  • a correction for subsequent containers is possible, for example, by replacing or compensating for pressure nozzles which are identified as defective by at least one adjacent pressure nozzle.
  • the multi-color printing is carried out in normal operation at half the resolution of each printhead, so using each second pressure nozzle. If a certain pressure nozzle fails, it can be replaced, for example, by the immediately adjacent pressure nozzle or by an adjacent group of pressure nozzles.
  • the containers are selectively rejected at the suppressed pressure.
  • the recognized as defective containers are then preferably no longer printed with the following inks or the correction pressure for the print mark to save ink.
  • the rejection of defective containers preferably takes place automatically downstream of the device used for the multicolor printing.
  • the motif is composed of partially circumferential printing areas and printed at least one print mark per printing area.
  • the individual partially circumferential pressure ranges can then be aligned and checked separately at their respective associated print mark. This can compensate for inaccuracies in the repositioning of the container for printing the individual pressure ranges.
  • all print marks are then overprinted.
  • this is for multi-color inkjet printing on container and comprises: a plurality of successive color stations each with at least one print head for printing the containers in an associated ink and with a subsequent inspection unit for optically inspecting the printed motif and / or at least one printed in the color stations print mark; a correction station following the color stations with at least one print head for selectively overprinting the print mark; a transport means with rotary supports for successively positioning the containers in the color stations and in the correction station; and a control unit for driving the rotational postures and the print heads depending on results of the inspection units.
  • the inspection unit is preferably designed such that it spatially selectively inspects the print marks in contrast to a complete inspection of the entire motif.
  • the inspection unit is then in particular capable of error detection, which is based on an imaging detection of contrast gradients and / or color gradients in the print marks, in particular by means of targeted evaluation of the previously applied ink.
  • evaluation algorithms run, which are specially designed for determining the position of registration marks and for the evaluation of color gradients or brightness gradients in color marks.
  • the print heads are preferably designed such that they each cover continuously at least the entire height of the motif to be printed on. In principle, it would also be conceivable to arrange several print heads overlapping in the vertical direction in order to cover the entire height of the motif.
  • the printheads preferably have a resolution of at least 1200 dpi.
  • the rotary supports include servomotors, and the maximum print height of the print heads is greater than the height of the subject. This will make an exact correction of the situation With a certain ink alsstruckendes motifs in both the vertical and in the horizontal direction allows.
  • the inspection units comprise cameras for total full-scale imaging of the containers.
  • several cameras can be present at least in the input-side inspection unit in order to completely inspect the containers with a plurality of partially circumferential camera images over the entire circumference.
  • the entire area of the motif to be printed on and the imprinted printed mark can be imaged and the quality of the printing can be determined on the basis of the printed mark.
  • This configuration could also be used in the subsequent inspection units.
  • a coarse alignment of the rotational position would be possible, for example, on the basis of container contours, for example an embossing. Since the rotational position of the container due to such an initial inspection of the container is then basically known and / or can be corrected accordingly, in the subsequent inspection and correction of the rotational position of the print marks only a relatively minor correction of the rotational position is necessary to deviations in positioning and Transporting the container in the individual color stations or to balance therebetween.
  • a possibly also not imaging optical sensor could be present immediately before each color station, which locates the registration mark comprising a registration mark and causes the immediately following color station and / or the turntable associated with the container by means of the control unit to correct the subsequent imprint.
