Definitions

  • Direct printing machine for applying a printing layer to containers
  • the present invention relates to a direct printing machine for applying a printing layer to a container according to the preamble of claims 1 and 8 and to a direct printing method for applying a printing layer to a container according to the preamble of claim 13.
  • Direct printing methods for printing on containers are known in the art over a wide range of resolution.
  • EP 2 089 234 B1 proposes a direct printing method in which a primer is applied to the container before it is provided with a printed image. From this it is known that ink drops with a resolution of 200 to 1200 drops / inch (dpi) and also different drop sizes can be applied to the surface of the container, for example to form a primer or at least a part of the printed image.
  • ink drops with a resolution of 200 to 1200 drops / inch (dpi) and also different drop sizes can be applied to the surface of the container, for example to form a primer or at least a part of the printed image.
  • the known method generally allows the application of a primer and the subsequent application of a printed image, but can not be ensured over the entire surface of the container due to the usable resolutions of a maximum of 1 .200 dpi and a drop size of 10 to 200 ⁇ that the applied Printing layer or primer is flat or nearly flat. Such unevenness may result in the subsequent application of a printed image to the flow of the printing ink in accordance with the relief produced by the primer, thereby reducing the print quality.
  • the technical problem to be solved is therefore to improve direct printing processes and direct printing machines for printing on containers with regard to the quality of the printed images.
  • the direct printing machine according to the invention is characterized in that the print head is oriented so that the nozzle rows form an angle greater than 0 ° with a plane perpendicular to the transport direction of the container. This clearly indicates that the print head is inclined with respect to the container in the transport direction. This reduces the spacing of the individual nozzles of the nozzle rows at least in the vertical direction, so that the pixel density in this direction can be increased beyond the output pixel density of the print head.
  • twice the ink drop density can be achieved, at least in the vertical direction. In this way, a much more uniform layer can be produced when the printing layer is applied, so that a color layer applied later to the printing layer can be produced more levelly and therefore with a higher quality.
  • printing layer is to be understood as any layer applied to the surface of a container by a printing module of a direct printing machine.
  • These include in particular colored layers (for example yellow, red or blue), but also functional layers, such as primers, which are applied to the container before the actual print motif is applied.
  • this primer may already be part of the image (for example, it may be white or cause certain other optical properties, or it may also have any color), it need not.
  • the primer may also be formed as a transparent layer or at least as a partially transparent layer, and e.g. affect the adhesive properties of the applied color layers for the printed image.
  • the primer may be made of a material that reduces or increases the surface tension compared to the actual surface of the container, which may be beneficial for wetting with the actual printing inks.
  • the nozzle rows enclose an angle that is perpendicular to the transport direction at an angle greater than 0 ° does not mean that they are arbitrary misalignments, for example due to a not completely exact alignment of another vertically arranged pressure module (the nozzle rows run as planned parallel to the plane perpendicular to the transport direction), but are intentional inclinations. As a result, they will generally be larger, even significantly larger than the tolerances acceptable for vertical alignment and will be in the range of a few degrees, in particular 5 ° to 30 °.
  • the nozzle rows are arranged in a plane in the print head, which is perpendicular to the transport plane. This means that the print head does not move in the direction of the transport plane or in the direction of a transport plane in the transport plane. th container is tilted, but just stands. Distortions of the printed image can be avoided.
  • the print head has a normal resolution of 1200 dpi.
  • the normal resolution means that this is the resolution that can be achieved on a flat substrate when the ink droplets strike the surface vertically.
  • the printing press comprises two print heads arranged one after the other in the transport direction, which are offset from each other perpendicular to the transport plane and each have a normal resolution of 600 dpi, wherein both print heads comprise at least two rows of nozzles and are aligned so that the nozzle rows with the Level perpendicular to the transport direction of the container include an angle greater than 0 °.
  • a suitable offset of the ink droplets applied by the printheads can be achieved, so that even with the comparatively low resolution of 600 dpi / printhead an ink droplet density can be achieved on the surface of the container , which is significantly larger than the sum of the ink drop densities of the individual printheads, for example, much greater than 1200 dpi, so that a layer as flat as possible is applied.
  • the print heads are offset from one another by a distance h which corresponds to half the distance between two adjacent nozzles of a nozzle row in the direction of the surface normal of the transport plane. That is, the ink droplets of the second printhead are placed on the surface of the container just in the interstices of the ink drops of the first printhead. In order for a uniform printed layer can be generated, which facilitates the application of the subsequent print layers and leads to an improved print image.
  • the printhead or printheads can be designed so that they can eject ink drops with a diameter of 10 to 50 ⁇ m.
  • the diameter of the ink droplets refers to the dimensions of an ink drop at normal pressure and room temperature in the equilibrium of forces, that is to say without any forces acting on the ink droplets in total.
  • one of the printheads may be configured to eject ink droplets having a smaller diameter than the other printhead. In this way, embodiments can be realized in which the gaps between the relatively large ink droplets can be filled by the smaller ink drops and thus a surface which is as flat as possible can be produced.
  • Another direct printing machine for applying a printing layer to containers is characterized in that the print heads are arranged offset from one another perpendicular to the transport plane by a distance h which is smaller than the distance between two adjacent nozzles in the nozzle row.
  • the ink drop density can be doubled in this direction (ie perpendicular to the transport plane of the container).
  • the most uniform printing layer can be applied, which can improve the quality of printed images applied to this printing layer.
  • the distance h is equal to half the distance between two adjacent nozzles in a row of nozzles.
  • one of the printheads may be configured to dispense ink drops having a smaller diameter than the other printhead.
  • the ink drops of the printhead come into contact with the ink droplets of the other printhead to eject smaller drops of ink, a uniform print layer can be achieved because the smaller ink drops fill the gaps.
  • the print heads have a normal resolution of 720 dpi and / or at least four rows of nozzles.
  • the achievable with such printheads maximum resolutions show good results in terms of the homogeneity of the applied print layer and thus improve the conditions for it to be applied printed images or other print layers.
  • each of the direct printing machines described so far comprises one or more adjusting devices, which are assigned to a print head and designed to change the relative position of the print head to the transport plane. It is intended in particular to a change in the position perpendicular to the transport direction and a change in the angle enclosed by a plane perpendicular to the transport direction and the rows of nozzles.
  • the settings of the printheads can be adapted to the requirements of the printing layer for the container, for example, depending on the container type or the degree of quality to be achieved.
  • the inventive method for printing on containers is characterized in that the containers are transported in a direct printing machine according to one of the preceding embodiments along a transportation line defining a transport plane and are equipped during transport with the print layer.
  • measuring transport does not necessarily mean that the containers undergo a movement along a transport direction in the transport device during the printing process.
  • the containers may also be stationary relative to the printheads during the printing process, or at least undergo rotation.
  • the ink drops applied to the container at normal temperature and pressure have a volume of 3 to 30 pl and / or a diameter of 10 to 50 ⁇ m and / or a distance of the center points after application to the container of FIG to 20 ⁇ , preferably 17.5 ⁇ have.
