Definitions

  • the present invention relates to a method for producing a decorated profile body, comprising the steps: providing a substrate; applying a decoration background; and applying by means of the digital printing process a decoration finish which covers the decoration background at least in some sections, wherein the decoration background and the decoration finish together form a decoration of the profile body.
  • reference decoration changes color when the type of light changes.
  • the color impression of the decoration of a profile body (e.g. edgeband) attached to the panel must change in the same way as the reference decoration, since otherwise the so-called metamerism effect occurs.
  • metamerism is defined in DIN 6172 and denotes an effect according to which two samples which look the same under one type of light exhibit a color difference under another type of light.
  • the decoration templates or template panels from the furniture industry exhibit a wide palette of color pigments and are usually printed using water-based inks, wherein a colored absorbent paper is used as the decoration carrier or substrate.
  • the choice of pigment for these printing inks is limited not at all by the method.
  • the inkjet printing process allows only a limited choice of color pigments.
  • the use of identical pigment types and sizes is primarily the basic prerequisite for a printed structure that exhibits no metamerism.
  • the color systems used are usually developed for the respective printing head and are specially adapted to the material to be printed.
  • the color composition usually takes place according to the CMYK principle, i.e. by combining the colors cyan, magenta and yellow and black (Key).
  • CMYK principle i.e. by combining the colors cyan, magenta and yellow and black (Key).
  • Key the colors cyan, magenta and yellow and black
  • the object of the invention is therefore to provide a decorated profile body and a method for the production thereof, according to which the entire color space of conventional printing processes, such as e.g. the gravure printing process, can be recorded also in the case of digital printing of the profile body, and thus a metamerism effect can be at least largely prevented.
  • conventional printing processes such as e.g. the gravure printing process
  • the present invention provides the method for producing a decorated profile body according to claim 1 , comprising the steps: providing a substrate; applying a decoration background; and applying by means of the digital printing process a decoration finish which covers the decoration background at least in some sections; wherein the decoration background and the decoration finish together form a decoration of the profile body; wherein the decoration background has a color composition consisting of an expanded color space compared to the decoration finish, wherein the color composition of the decoration background is selected in such a way that essentially no metamerism effect occurs between the decoration of the profile body and a reference decoration which is similar, preferably identical, thereto.
  • Digital printing processes means digitally controlled printing processes, such as e.g. inkjet printing processes, toner processes (e.g.
  • the invention builds essentially on the fact that the decoration background and the decoration finish together form the visible decoration of the profile body.
  • the decoration finish is applied e.g. according to the CYMK principle using the inkjet printing process and has the limited color space.
  • the decoration background expands the limited CYMK color space by a targeted choice of colorant so that, even when the profile body is printed digitally with a color composition according to the CMYK principle, the entire color space of conventional printing processes, such as e.g. the gravure printing process, can be recorded and displayed, and thus a metamerism effect can be substantially prevented.
  • a metamerism effect can be substantially prevented.
  • the decoration finish is applied to the substrate before the decoration background.
  • the decoration background comprises two differently colored base layers. These differently colored base layers will be referred to below as the universal base layer and the individual base layer.
  • the so-called universal base layer is applied to the substrate in order to even out any irregularities (e.g. color nuances, etc.) of the substrate which are brought about by the manufacturing process or to neutralize the substrate from the color point of view, so that the decoration can be reproduced with high precision and color accuracy.
  • the substrate is kept in stock for further processing.
  • the so-called individual base layer is preferably applied only once the specific intended use is known, and may already contain a basic shade of the decoration that is to be achieved.
  • the individual base layer may already be colored in a shade corresponding to the basic shade of the reference decoration, wherein the decoration of the profile body is preferably matched to the reference decoration.
  • the individual base layer preferably contains an individually mixed special color, wherein the color composition of the individual base layer is selected from an expanded color space compared to the decoration finish.
  • the decoration finish has e.g. a color composition selected from the CYMK color space.
  • the color space of the decoration of the profile body can be expanded beyond the given color space of the pure scale colors.
  • the fine-tuning of the shades of the individual base layer and of the decoration finish may take place by means of suitable software.
  • the individual base layer may be, but does not have to be, part of the visible decoration of the profile body. However, a part that is not openly visible nevertheless has a considerable influence on the appearance and the color effect of the decoration of the profile body, since the decoration finish usually does not provide complete coverage, due to non-covering pigments.
  • this effect can be used to control the individual base layer in such a way that the change in color of the decoration of the profile body when the light changes takes place in the same way as the reference decoration, and thus metamerism effects can be avoided.
  • a translucent or transparent substance is applied at least in some sections as the decoration finish, e.g. by using non-covering pigments.
  • results which are particularly pleasing from the optical and esthetic point of view can be achieved.
  • the design scope is considerably expanded as a result, since the layers of the profile body which are located below the decoration finish can also be included in the visible decoration and can thus contribute to the optical and esthetic overall impression of the profile body.
  • the decoration finish is radiation-cured.
  • the drying time of the decoration finish can be considerably shortened as a result.
  • the substrate is made from a polymeric material, in particular plastic.
  • the principle of the invention can be implemented with particular advantage.
  • the application of colored decorations to such substrates is usually more challenging than to paper-containing substrates for example. Due to the decoration background, the adhesion of colored decorations to polymeric substrates is considerably improved and the color choice for the image on the decorated profile body is considerably expanded.
  • the substrate is an extruded profile, preferably an edgebanding profile, a wall connection profile, a window profile or a roller shutter profile, or else alternatively a film, e.g. a calendered film.
  • Such substrates or profile bodies are often used in conjunction with other decorated objects, such as e.g. kitchen worktops, table tops, cabinets, etc., where a high-quality optical and esthetic appearance of the product depends on the most accurate possible matching of the decorations, specifically against the background of the metamerism effects which occur when the light changes.
  • a decorated profile body can be provided which satisfies, specifically against this background, the strictest optical and esthetic requirements. Due to the multilayer structure of the decoration background in conjunction with the decoration finish to be applied to the decoration background, color and decoration nuances can be displayed in much greater detail than was previously the case with conventional decorated profile bodies, and the decoration of the profile body can thus be better matched to a reference decoration.
  • At least one base layer is single-colored.
  • At least one base layer is colored in a dark shade.
  • coloring the decoration background, in particular the universal base layer in a dark shade, there is a reduction in the coloring effort and in the amount of ink to be applied for the individual base layer and the decoration finish if the intention is to produce an image with a rather dark shade.
  • An intermediate product with the decoration background, in particular the universal base layer, being colored in a dark shade is therefore provided for creating the image with a rather dark shade.
  • At least one base layer is colored in a light shade, preferably white.
  • a light shade preferably white.
  • An intermediate product with the decoration background, in particular the universal base layer, being colored in a light shade is therefore provided for creating the image with a rather light shade.

  • the decoration background in particular the individual base layer, in a shade corresponding to the basic shade of the decoration finish, there is a reduction in the amount of ink to be applied for the decoration finish. Furthermore, color and decoration nuances can be displayed in a particularly detailed manner as a result and can be matched to the reference decoration.
  • At least one base layer is applied by means of the digital printing process, e.g. the inkjet printing process.
  • the costs of carrying out the method according to the invention are considerably reduced.
  • At least one base layer contains a solvent-based ink, a radiation-curable ink, preferably a UV-curable ink, and/or a water-based ink.
  • a solvent-based ink preferably a solvent-based ink, a radiation-curable ink, preferably a UV-curable ink, and/or a water-based ink.
  • Such inks can be used with particular advantage in the method according to the invention.
  • At least one base layer is applied over the entire surface and/or in a covering manner.
  • the construction of the profile body according to the invention is simplified.
  • a color choice for a layer of the profile body arranged below the covering base layer need not be made on the basis of optical and esthetic aspects.
  • the profile body according to the invention has two base layers.
  • the thickness of the base layers is preferably in each case between 1 and 500 ⁇ m.
  • At least one base layer is applied in such a way as to form at least one depression and at least one raised area.
  • three-dimensional decorations with a particularly spatial effect can be displayed, which further broadens the design scope compared to conventional profile bodies.
  • the decoration finish is applied essentially in the region of at least one depression of a base layer.
  • the substrate applied as the decoration finish exhibits particularly good adhesion, and particularly pleasing images having a depth effect can be displayed.
  • the decoration finish is applied in such a way as to substantially fill the depression. This considerably facilitates the application of the decoration finish and prevents any smudging, smearing or running of the substance applied as the decoration finish.
  • the thickness of the decoration finish is the complement of the thickness of the decoration background, so that the decoration background and the decoration finish are applied with a constant overall thickness. As a result, despite the depth effect of the image, a decorated profile body which has a smooth surface can be produced.
  • a transparent or translucent substrate is provided and the decoration finish is applied to the rear of the substrate before the decoration background.
  • the profile strip can be attached by its rear to an object, with the decoration of the profile body still being visible through the transparent or translucent substrate.
  • the decoration is not impaired during subsequent machining of the front visible edges of a profile body designed as an edgeband.
  • the decoration is also protected against any other mechanical effects.
  • moving the decoration of the profile body to the rear side of the substrate makes it possible to achieve a spatial “3D” effect which optically and esthetically enhances the appearance of the profile body compared to decoration on the front side and considerably expands the freedom of design.
  • One preferred embodiment of the invention relates to an object comprising at least one decorated surface and a decorated profile body produced by the method according to one of the preceding embodiments, wherein the object comprises the reference decoration to which the decoration of the profile body is matched in such a way that essentially no metamerism effect occurs.

  • the ink systems used for the universal base layer 4 are solvent-based inks, UV-curing inks and water-based inks.
  • the universal base layer 4 is opaque, i.e. it covers preferably the entire surface of the layer located therebelow (the substrate 2 or the primer layer 3 ).
  • the universal base layer 4 is colored in a light or dark shade in order to be able to carry out a basic sorting for further processing.
  • a substrate 2 with a universal base layer 4 in a light shade e.g. white
  • a substrate 2 with a universal base layer 4 in a dark shade is provided for creating an image with a dark basic shade.
  • This precursor product manufactured in this way is then kept in stock and held ready for final processing.
  • the individual base layer 5 is applied to the universal base layer 4 .
  • the universal base layer 4 is selected in such a way that as little additional coloring as possible by the individual base layer 5 is required. In general, it is possible for example in extreme cases to work only with a few universal base layer colors.
  • the individual base layer 5 is opaque, i.e. it covers preferably the entire surface of the universal base layer 4 located therebelow and is colored in a shade which corresponds to the basic shade of a decoration template such as a decorated surface 9 of an object 8 (e.g. table top or kitchen worktop; FIG. 3 ) and the basic shade of the decoration finish 6 .
  • the individual base layer 5 may be applied conventionally by means of printing rollers or likewise in the digital printing process, e.g. via a special inkjet printing device with an expanded color space (special color space).
  • the possible ink systems which can be used for the individual base layer 5 are selected from solvent-based inks, UV-curing inks and water-based inks.
  • the decoration finish 6 is applied by an inkjet printing device in the inkjet printing process (inkjet process).
  • the decoration finish 6 has a color composition consisting of the CMYK color space, i.e. a combination of the colors cyan, magenta and yellow and black (Key).
  • the decoration finish 6 is usually applied as a glaze and does not cover the entire surface, and is therefore applied as a transparent or translucent substance.
  • Targeted pigment selection and mixing of the color of the individual base layer 5 helps the decoration of the profile body 1 to change color in the same way as the reference decoration when the light changes, so that essentially no metamerism effect occurs.
  • the decoration finish 6 is preferably applied to the individual base layer 5 only in some sections, preferably only in the regions of the depressions 51 in order to fill these depressions 51 .
  • the thickness of the decoration finish 6 behaves inversely to the thickness of the individual base layer 5 , so that the overall thickness (sum of the thicknesses) of the individual base layer 5 and of the decoration finish 6 in each case remains constant.
  • the substance applied as the decoration finish 6 is preferably radiation-curable, preferably UV-curable, and is cured as a result of exposure to a radiation source.
  • a clearcoat layer 7 is additionally applied in order to seal and protect the decoration of the profile body 1 .
  • the color space of the decoration of the profile body 1 (consisting of the decoration background 4 , 5 or universal base layer 4 and individual base layer 5 and the decoration finish 6 ) can be expanded by the given color space of the pure scale colors.
  • the individual base layer 5 is integrated in the image or color composition of the decoration of the profile body 1 and is taken into account when defining the color.
  • the principle of the invention can be applied to any substrate 2 and is suitable in particular for polymeric substrates 2 such as extruded plastic profiles, in particular edgebanding profiles, wall connection profiles, window profiles and roller shutter profiles, but also for example films, e.g. calendered films, in particular films having a layer thickness 0.05 mm, preferably a layer thickness of 0.2 to 0.4 mm.
