Definitions
- the present invention relates to a method for printing inks on a substrate, as well as to a substrate obtained by using such a method.
- rotary printing technology such as rotary screen printing
- the negative of the image to be transferred is placed on the outer circumference of a so-called printing cylinder.
- the printing cylinder is then brought into contact with the substrate, which substrate usually has a dimension several times larger than the outer circumference of the cylinder.
- the substrate is passed under or over the pressure cylinder so as to be printed in a continuous process.
- objectionable repetitions is reduced by reducing the contrasts in the print and by removing characteristic elements from the original, for example by retouching.
- the objectionable repetitive effect can be partially eliminated by decreasing the degree of contrast and by retouching, a drawback being the fact that the original image will lose some of its quality.
- the substrates are much larger than the original image that is available.
- exact repetitions i.e. identical repetitions of the original image.
- Such a method is known from European patent application No. 0 558 008.
- the result thus obtained clearly exhibits transitions between the individual image elements, which transitions can only be masked by arranging the figurations present on the image elements contiguous to each other. The transitions are not adapted by means of software.
- Another consequence of using the printing cylinder for printing substrates is that a different printing cylinder provided with an associated pattern must be used each time a different image is to be placed on the substrate. In practice this means that a large stock of printing cylinders is needed. Moreover, frequently exchanging a printing cylinder in a printing process is a labour-intensive operation, during which the printing process must be stopped for some time.
- Another object of the present invention is to provide a method for printing inks on a substrate, which method proceeds from an original image of random size, whereupon a substrate of random size is printed with an image derived from the original image, with smooth transitions being obtained in the image being printed on the substrate.
- processing said digital file to obtain a processed digital file, which processed digital file is made up of a number of compositions of the original image
- step i) printing the substrate by means of said printing unit, wherein the processed file is printed on the substrate by the printing unit as a processed image of the original image, using inks, wherein the original dimension of the original image used in step i) is smaller than the dimension of the processed image being printed on the substrate by the printing unit.
- Step i) is carried out by, for example, scanning, photographing or generation via design software, or a combination thereof.
- Step i) may also comprise the making of corrections in the digital file, for example via Photoshop (trademark).
- the digital file thus obtained is processed by means of a computer in step ii), using the original image, or one or more parts thereof, as a basis for generating comparable images, thereby creating a processed digital file.
- Such an operation comprises, for example, selecting a number of blocks or parts of the original image and subsequently positioning said blocks or parts at random positions, whereupon the boundaries or edges of the thus positioned blocks or parts are processed for the purpose of camouflaging or blurring the visually distinguishable transitions between said blocks or parts and the surface on which said blocks or parts are positioned via software.
- the selection of blocks or parts takes place via random routines, in which the size, dimension and location of the blocks or parts can be determined at random.
- the processed digital file is made up of individual images, such that the extent to which the transitions between such individual images are distinguishable is minimized via software applications.
- the processed digital file according to step ii) is preferably made up of a number of computer-processed compositions of parts of the original image.
- the processed digital file is sufficiently large for printing the entire substrate without the processed digital file being composed of a number of objectionably distinguishable repetitions of (parts of) the original image and without any objectionable joints. If the dimension of the processed, digital file is not sufficiently large for covering the substrate, several of such files can be processed anew via the aforesaid route so as to obtain a new file in which the occurrence of objectionable joints or transitions between the respective images is prevented.
- petitions is understood to mean computer-processed compositions of (parts of) the original image.
- the inks used in step iv) contain one or more components selected from the group consisting of pigments, colorants, stabilisers, flow agents, viscosity modifiers, anticoagulants, antistatics and fillers, as well as the additives commonly used for inks.
- step ii) that the thus processed digital file can be regarded as a computer-synthetised version of the original image, in which transitions between the aforesaid repetitions or computer-processed compositions in the processed file are smoothly executed, or even do not occur at all.
- the processed, digital file according to step ii) is preferably built up so that the occurrence of exact parts, repetitions of the original image, is minimized or even altogether absent.
- a suitable substrate is a cellulose fibre-containing substrate, in particular paper.
- the substrate may also comprises a crosslinkable or curable resin.
- crosslinkable resins include thermally curable resins.
- resins that can be crosslinked by means of UV and EB (Electron Beam) radiation, viz. resin compositions based on (meth)acrylates, have been found to be suitable.
- the present application in particular relates to the printing of a surface, such as paper, and is not in any way related to animations for electronic games, virtual reality and Internet-based environments.
- the method of printing in step iv) is preferably selected from the group of digital printing and inkjet printing.
- inkjet printing makes it possible to print digital files with a high degree of precision, not using printing cylinders.
- inkjet printing it is possible to use special ink compositions which exhibit advantageous properties in the field of weather resistance.
- the substrate is supplied on a supply roll, which roll is unwound, with the substrate being supplied to the printing unit at a certain conveying velocity. It is also possible to use loose plate materials as a substrate. Paper can be used as a suitable substrate, for example paper which is used as wallpaper after being subjected to the present method. Particularly suitable are resin-impregnated papers, which papers are used for producing HPL, with the panels thus obtained being used both indoors and outdoors, for example as facade cladding materials.
- the printing unit places the processed digital file on the substrate in the form of an image, using inks.
- the substrate thus treated is wound onto a roll and is ready for a next process step, for example cutting the printed substrate to the desired dimension.
- the structure-synthetising software module makes use of routines selected from the group of random generation routines, fractal routines, static reaction diffusion, Markov, pyramid-based, hybrid routines and rendering routines for converting the original image of step i) into a digitally processed image, wherein the extent to which exact copying of the original image takes place is minimised.
- routines selected from the group of random generation routines, fractal routines, static reaction diffusion, Markov, pyramid-based, hybrid routines and rendering routines for converting the original image of step i) into a digitally processed image, wherein the extent to which exact copying of the original image takes place is minimised.
- parts of the original image can extended/reduced and/or be rotated through a random angle.
- the shape, size and location of the blocks (patches) or parts of the original image can be determined by the structure-synthetising software module in addition to the desired resolution.
- the structure-synthetising software module comprises mathematical routines in which the essence of the original image is captured in a dataset, which is used as input for the random generation routines.
- Texture or structure synthesis is an image-based rendering method for constructing large images from small original images, making use of abstraction of the texture information of the original image.
- texture synthesis algorithms allow the combination of several images for forming seamless and non-repetitive images of any size that may be selected.
- the object of a texture synthesis algorithm is to create an output image which complies with one or more of the following criteria.
- the present invention further relates to a substrate provided with a print, which print has been obtained after digital processing of an original image and which comprises a number of repetitions of the original image, the dimension of said print being larger than the dimension of the original image, wherein the extent to which the transitions between the images in the print are distinguishable has been reduced to a minimum.
- the substrate is a plate or a sheet, wherein in particular the texture-synthesized image is larger than the sheet or a panel that is cut from the eventual product.
- the present substrate can be used as decorative paper, which decorative paper is used for producing HPL.
- the decorative paper is placed on a stack of resin-impregnated paper layers, for example, and compressed at an elevated pressure and temperature to form a panel.
- a printing cylinder having a circumference of 1.2 m is used for printing an endless paper substrate.
- the thus covered substrate is processed into plates used for cladding building facades having a surface area of 100 m 2 .
- the facade panels are made in a width of 2 m.
- the facade structured comprises at least 416 images having the same characteristic structure. Such a facade exhibits an unnatural regularity and an architecturally undesirable picture, in which the transitions between the individual panels can be regarded as objectionable.
- the starting point is a scan of a flat piece of wood having a dimension of 30 ⁇ 30 cm. Said piece of wood was scanned and processed with Photoshop for adjusting the colour and contrast as required. Furthermore, a few objectionable defects in the image were retouched. Subsequently, the digital image was input into a texture synthesis algorithm. Said algorithm was instructed to create a processed image having a resolution of 30 dpi and a dimension of 1860 ⁇ 3005 mm on the basis of the original image.
- This processed image is then input into the RIP software of the inkjet printer and subsequently printed on a roll of paper.
- a space of 5 mm is left open between the individual images, where cuts are made in a next process.
- sheets of 1860 ⁇ 1500 mm can be cut, which can be affixed to a plate of 1860 ⁇ 1500 mm.
- the method in this example leads to plate materials all carrying the same print, the image is repeated only 18 times for each facade having a surface area of 100 m 2 . If the original scan is passed through the texture synthetising routine for each individual plate, the occurrence of repetitions in a facade can even be prevented altogether.
