Definitions

  • the invention relates to a method for printing surfaces of three-dimensional objects with cylindrical or curved surfaces, such as bottles or cans, by means of inkjet print heads, in which a preferably white or differently colored, in particular opaque, basic color layer is printed on the three-dimensional object and a further color layer is printed on it.
  • the further color layer can consist of one or more colors, which are printed in a printing layer with an inkjet print head or in several printing layers with several inkjet print heads of different colors as a mixed color and optionally result in a preferably structured image.
  • a coating in particular composed of one or more transparent or partially transparent, colorless or colored lacquers, can also be applied.
  • the coating can in particular be applied by printing, for example with an inkjet print head operating in digital printing.
  • basically known coating methods can also be used for the coating, for example a spray coating.
  • a correspondingly printed three-dimensional object in particular a container such as a bottle or a can, is described.
  • Printing machines which print on curved surfaces with drop-on-demand ink jet print heads.
  • colors are usually printed as cyan (C), magenta (M) and yellow (Y) with black (K) one after the other on the object with the curved surface that is moved relative to the inkjet printheads and create the color impression or that on this surface colored print image.
  • C cyan
  • M magenta
  • Y yellow
  • K black
  • a base color layer is usually first printed, which is often white in order to create a better opacity.
  • other colors can also be used for this, which in principle can also help to graphically shape the print image of the color layer.
  • the US 8,522,989 B2 describes digital printing of three-dimensional bodies with an in particular curved surface, in which a base layer is applied at least in sections to the three-dimensional body.
  • This base layer can be transparent or opaque.
  • Further elements, such as labels, can be printed on this base layer for graphic design. This creates a three-dimensional effect that allows the label to protrude from the base layer.
  • An inverse print is described as a further design element, in which specially shaped recesses are left free when the base layer is printed on. This achieves an effect in which the elements produced by the lack of the base layer in the exposed areas appear set back in relation to the base layer.
  • the base layer which differs from the three-dimensional body in particular in terms of color and / or by its thickness / brightness, is according to the teaching of US 8,522,989 B2 thus used specifically to contrast design elements.
  • the edges of the base layer or the print job should specifically achieve a three-dimensional effect and be visible.
  • the three-dimensional body which is transparent, for example, is not to be provided over a large area with an, for example, opaque basic color layer, because the view of the product contained in the body is to be retained.
  • This is often the case, for example, with transparent beverage bottles, if they are only to be printed with a label or an inscription, possibly even in multiple colors, or the three-dimensional body for other reasons, e.g. due to a particularly high-quality surface, should not be coated beyond the print image (print area).
  • the (mostly differently colored, especially white) base color layer shines through at the edges of the print image. This effect occurs particularly due to the relative movement between the surface of the three-dimensional object to be printed and the drop of ink that hits this surface.
  • Fig. 1 schematically shows the imprint 11 on a three-dimensional object 12 as a result of a conventional printing process.
  • a primer 13 in the sense of a primer is applied directly to the surface of the object 12.
  • the (in particular white) first basic color layer 14 is applied to the primer 13, and the multicolored color layer 15 is then applied in several Printing processes is printed as a structured print image.
  • the color layer is protected by a coating 16 in the sense of a varnish or top coat.
  • the white (or also differently colored) base color layer 14 looks out from under the actual color.
  • an adhesive substrate usually referred to as a primer
  • a coating which is also referred to as a varnish / top coat in the sense of a top coat, can be printed on or otherwise applied.
  • This coating is intended to protect the printed image from damage.
  • the coating is usually a lacquer, but according to the invention can also consist of another material, for example a transparent and preferably also color-neutral plastic layer in the sense of a plastic coating.
  • the primer 13 and the coating 16 are in Fig. 1 also shown.
  • the DE 44 38 536 A1 discloses a method for coating a transparent carrier plate in regions with an active layer which is applied in the roller embossing process.
  • a protective layer is applied to the active layer and, if necessary, further layers are applied so that the active layer and any further layers in these areas are resistant to chemical etching. As a result, during an etching process, the active layer and any further layers are etched away only in the area not covered by the protective layer, and the protected area remains.
  • the WO 2011/064075 A2 discloses a method and an apparatus for generating a three-dimensional surface structure on a workpiece.
  • the WO 2010/104707 A1 describes an electroluminescent structure with an electrode layer, a phosphor layer over the electrode layer and a transparent electrode layer over the phosphor layer.
  • two protective layers are applied on both sides to protect the electroluminescent structure.
  • a light-storing layer is disclosed, which is overprinted with a further transparent protective layer, which makes it possible to write on it.
  • the layers are produced using a screen printing process or transfer printing.
  • the WO 2013/088950 A1 describes a method for printing the curved side surface of a car tire, in which a print head with a plurality of nozzle groups is laterally displaced relative to the print image during printing. This results in a stepped overall structure of the print image, in which each image part is printed several times on top of one another by different groups of nozzles.
  • a digital printing system includes a conveyor mechanism, a printer, and a curing device.
  • the printer has three printheads that apply three different inks, cyan, magenta and yellow.
  • the printheads allow full color printing of a digital graphic image directly on a bottle.
  • the digital printing system also enables the immediate exchange of another digital graphic image for the next bottle.
  • the digital image is created on a computer by a software program or produced by a digital camera that transmits the image to a computer via a hard drive.
  • document US 2013/0100186 A1 discloses a printing system that includes an inkjet printer and a paper transport unit.
  • the paper transport unit supplies a paper from a paper roll to an application unit and, after printing, discharges the paper via a discharge roller.
  • a carriage on which a print head is mounted moves in the application unit.
  • the printhead ejects ink to create an image on the paper.
  • a cutting device is provided for cutting the ejected paper into a predetermined size.
  • the JP 2012 - 232771 A discloses a method and apparatus for printing seamless cans.
  • a white coating can be formed on an outer surface of the seamless cans, which covers a base color of the metal and enables a more vivid print image.
  • a white, continuously printed layer can also be formed.
  • US 2013/0135383 A1 deals, inter alia, with an ink jet printing method for printing a printing medium with a white coating layer and a layer with a non-white pattern.
  • a resolution of the white layer can be selected to be greater than a resolution of the layer with the non-white pattern.
  • the object of the present invention is that by digital printing by means of inkjet print heads on the surface of a three-dimensional To improve the quality of the printed image generated object with a curved, for example cylindrical, surface.
  • the base color layer which in particular form the first color layer
  • the individual layers are thus built up from different printing specifications, in particular with regard to the size of the area to be printed or coated, in such a way that the disadvantages described above are avoided. Since the ink layer printed on the first ink layer is larger than the first ink layer, it preferably covers the first ink layer in all directions, which therefore no longer appears as a disruptive edge at the edge of the printed image.
  • the first color for example a white color layer (also referred to as the base color layer)
  • the base color layer is printed smaller than the overlying image composed of other colors that are printed in the further color layer.
  • the difference in the size of the print of the individual layers is usually only a few pixels. These falsify the print in a visually invisible way.
  • a coating be printed over the ink layer. This can be done directly on the color layer or only indirectly, ie after application of a possibly further intermediate layer, such as a mask, a security feature or the like.
  • the coating forms the top layer after printing, ie the top layer on the finished product printed and / or processed object, in particular in the sense of a ready-to-use object.
  • the coating thus forms a protective layer for the application layers underneath (such as, in particular, the color layer and the first color layer, also referred to as the base color layer).
  • the coating is therefore also referred to as a topcoat or protective lacquer layer (varnish / topcoat).
  • topcoat varnish / topcoat
  • properties of the topcoat can be designed in such a way that, in particular, it protects the colors from water, since the inks commonly used in the inkjet printheads are based on acrylate and have only limited water resistance.
  • the coating is made wider than the (in particular imaging) color layer and / or the base color layer. More broadly, in the sense of the invention, it is to be understood that the extent of the coating extends beyond the extent of the color layer at least in one direction, but preferably in all directions on the surface of the three-dimensional object. The same applies to the basic color layer. Since the top or protective lacquer layer (varnish / top lacquer) formed by the coating is wider or larger than that The color layer that creates the actual print image of the imprint also protects the open edges of the print image.
  • the embodiment of the method proposed according to the invention provides that the first color layer or base color layer is printed or formed smaller than the color layer and possibly the coating.
  • the colored layer can be built up from several colored layers overlying the first colored layer or base colored layer. The edge of the base color layer is thus also covered by the color layer and / or the coating.
  • smaller is to be understood as meaning that the extension of the first color layer (also referred to as the base color layer in the context of the disclosure) is the extension of the color layers applied thereafter (in the context of the disclosure also collectively referred to as the color layer) at least in one direction, but preferably in all directions on the surface of the three-dimensional object.
  • the color layer (applied later) is wider than the base color layer or first color layer in the sense that the extension of the color layer extends beyond the extension of the first color layer at least in one direction, but preferably in all directions on the surface of the three-dimensional object.
  • the basic color layer can of course also be used in the print image, for example, in order to form a visible background color or a color of the multicolored print image. If only a single color design is necessary for the print image, the base color layer (in the desired print motif) can be applied directly to the surface of the three-dimensional object or a primer intended for it can be printed. In such an application, which is not covered by the invention, the further color layer is then missing.
  • a coating applied, in particular printed, over the color layer which is formed, for example, by a lacquer protective layer and acts as a varnish / top lacquer, in turn covers the color layer and / or the base color layer and thus forms protection both for the surface and the edge of the Color layer with the print image. If the color layer is missing, the same applies to the base color layer.
  • the degree for this will be selected by the person skilled in the art, in particular as a function of the printing press and the printing inks or varnishes or varnishes used, according to their properties in printing or during application, possibly by printing and / or application tests. It is advantageous if the measure the overlap in the process can be parameterized in order to be able to adapt the process to different operational situations.
  • the basic color layer based on the print resolution of the color layer specified in pixels in the sense of pixel points which is defined by the structure and control of the inkjet print heads based on the relative movement to the object, is in the range between 1 to 100, according to the invention 5 to 30 pixels smaller than the paint layer. This is sufficient for the color layer to cover the base color layer. The same can also apply to the other layers.
  • the coating based on the print resolution of the color layer specified in pixels, which is defined by the structure and control of the inkjet print heads based on the relative movement to the object, is at least in the range between 1 and 100, preferably 5 up to 30 pixels larger than the color layer. This is sufficient for the coating to cover the layer of paint.
  • the coating can also be made larger according to the invention, for example in addition to the print image or the imprint, which in particular includes all of the layers applied beneath the coating using the inventive method, also other areas of the surface of the three-dimensional object.
  • the color layer representing the actual print image ie possibly also containing a graphic motif
  • the base color layer is reduced in size relative to this color layer. If necessary, the coating is enlarged in relation to this color layer. If the color layer is missing, for example in the case of a single-color print which is produced by the base color layer, this base color layer is used as a reference for the size in such cases that are not according to the invention of the print because it then defines the visible size of the print image generated by the print. This ensures that the representation of the print image containing the motif to be printed is not distorted.
  • a primer also referred to as a primer
  • This primer is additionally applied under the base color layer according to the invention.
  • This primer is preferably colorless and transparent in order not to influence the further design of the print or print image.
  • Such a primer may be necessary - in a manner known per se - depending on the nature of the surface of the three-dimensional object to be printed, so that the individual layers (base color layer and possibly further color layer) adhere adequately to the surface and do not smudge. Therefore, the primer is usually printed or applied directly to the surface of the three-dimensional object. Suitable primers vary accordingly depending on the substrate and are known to the person skilled in the art.

  • the additional primer can be omitted.
  • the base color layer then represents a colored primer that can appear transparent or opaque.
  • the primer is wider than the color layer and thus the colored print image created in the color layer in order to come into direct contact with the coating.
  • the primer is preferably wider or narrower than the coating.
  • the coating ends up on the primer. This means that when a transparent or partially transparent primer is applied as a primer, this primer is wider than the print image and also wider than a possibly applied transparent or partially transparent topcoat, so that there is sufficient substrate for each layer or color layer above it . On the other hand, if the primer is narrower or smaller than the coating, the coating covers the primer.
  • the base color layer and the color layer are enclosed by the coating and the primer in this structure, so that the two layers (which decisively determine the optical impression of the printed image), i.e. in particular the color layer and possibly the base color layer and possibly others, are not here Layers described in detail are well protected against environmental influences.
  • primer as a primer and a topcoat as a coating should be crosslinked so that the colors between the two layers (color layer and base color layer) are, so to speak, "welded" in the packet and are thus optimally sealed off from environmental influences.
  • the coating is wider than the primer (or the primer is narrower than the overlay). Then the coating, which usually ensures the best protective effect with regard to external environmental influences, extends directly to the surface of the three-dimensional object. This prevents, for example, a solvent from loosening the primer from the side, eating under the primer layer and leading to detachment of the entire print or parts of it from the printed surface.

  • the special thing about it is that superimposed layers produced in successive printing steps become wider towards the top, so that they also cover the edge of the layer underneath.
  • the three-dimensional objects can particularly preferably be bottles, cans or other, in particular bottle-shaped, containers which are printed in such a way that the aesthetics of these containers or bottles is retained in accordance with the proposed printing method.
