Definitions

  • the present invention relates to a printed paper sheet for manufacturing decorative panels, as well as to such decorative panels and items of furniture comprising such decorative panels.
  • the invention also relates to a method for manufacturing such items of furniture.
  • More particularly the invention is related to a printed paper sheet that carries the digitally printed pattern for a plurality of such decorative panels.
  • printed paper sheets for the manufacturing of decorative panels are produced by rotogravure or offset printing. Such sheets comprise a continuous pattern with a repeat in the length direction of the paper sheet about every 1.3 to 1.5 meters.
  • a substrate such as to a chipboard or an MDF or HDF board
  • a large decorative laminate board is obtained that is cut up to a plurality of decorative panels. Each panel features a part of the printed pattern.
  • the cutting process can be controlled so as to produce as few scrap as possible. Items of furniture manufactured from such decorative panels look quite fake and the design of the individual panels cannot be controlled.
  • EP 1 953 005 describes a prior art technique for the preparation of digital images to be printed on paper sheets for the manufacturing of laminate panels, such as flooring panels. The technique allows obtaining an embossed-in-registration structure on such flooring panels in a cost-effective manner.
  • WO 02/00449 it is known to provide decorative panels for kitchens with predetermined digitally printed patterns, wherein these panels have different sizes and the print is provided directly on a substrate of such panel. Prior to printing, the substrate is cut to size and provided with a veneer or synthetic surface layer. Printing panel by panel places a high burden on the manufacturing. It is especially difficult to maintain color accuracy, panel after panel, while printing directly on a substrate. Moreover a printing error results in a scrap panel.
  • a similar panel-after-panel printing technique is known from US 2007/001,558, wherein, in this case, preferably a single-pass printing equipment is used. The printed pattern is formed on a paper sheet, either before or after it being applied to a furniture substrate.
  • US’588 is concerned with decorative panels that are finished by applying a layer of a UV protective coating overtop, such as an acrylated coating. Such coatings are easily scratched and the technique of US’588 does not enable relief features to be embossed in the surface of the decorative panel, wherein these relief features would match the printed pattern of the panel. Upon cutting the decorative panel to its final shape splitting might occur in the printed paper.
  • a UV protective coating overtop such as an acrylated coating.
  • the present invention concerns a printed paper sheet for manufacturing decorative panels, wherein said paper sheet carries the digitally printed pattern for a plurality of said decorative panels, with as a characteristic that said plurality of said decorative panels comprises at least two panels of different size and in that predetermined, preferably distinct, portions of the paper sheet comprise the digitally printed pattern at least for said two decorative panels.
  • the method of the present invention allows to custom design the printed pattern of each of the decorative panels, while keeping the burden of manufacturing low. Indeed such paper sheet can be processed in the traditional laminate board manufacture plant, and can be cut up much alike the traditional laminate board.
  • the cutting scheme however needs to be adapted in accordance with the position of the predetermined portions of the printed pattern.
  • the predetermined portions are positioned so as to minimize the creation of scrap portions while cutting up.
  • one such printed paper sheet comprises the predetermined portions for a number of different decorative panels comprised in the same unit of furniture, e.g. one or more front doors, one or more side panels, one or more top or bottom panels.
  • Preferably said predetermined portions can be cut from the sheet by means of cuts parallel to the edges of the paper sheet only and/or by means of continuous cuts only.
  • cutting is normally carried out while the paper sheet is already adhered to a substrate to form a decorative laminate board.
  • a continuous cut it is meant a cut that completely separates a part from the board or from the remainder of the board, after other parts have already been cut off by way of continuous cuts only. Indeed, it should be noted that these cuts are not necessarily performed on the entirety of the laminate board, but possibly on already separated portions thereof.
  • the present preferred embodiment allows cutting up of the laminate board comprising the printed paper sheet of the invention in a convenient way using standard machinery.
  • a printing error in the method of the invention leads only to the loss of a printed paper sheet or part thereof.
  • the print could be performed with the paper sheet already adhered to the board substrate.
  • said digitally printed pattern is a wood pattern.
  • stone patterns or fantasy patterns can be used as well.
  • the respective portions of the wood pattern are predetermined in that their size corresponds to the size of the respective decorative panel. Of course, preferably their size is somewhat larger to allow for tolerance while cutting up or further processing the decorative panels.
  • the respective portions of the wood pattern are predetermined in that the wood pattern depicts a central wood part bordered by several further wood parts such that the central wood part corresponds to the centre of the decorative panel and the several further wood parts correspond to the border of the decorative panel.
  • said predetermined portion preferably has a pattern adapted to the respective decorative panel.
  • a pattern adapted to the respective decorative panel For example, when use is made of the above mentioned central wood parts, such wood parts will be larger for a larger decorative panel, than it is for a smaller decorative panel.
  • the digitally printed pattern of the respective panels is free from repetition, even if one or both decorative panels have a dimension larger than 1,5 meter.
  • Preferably said predetermined portions are bordered by unprinted areas of the paper sheet or by areas that comprise a distinctly different printed pattern, such as a uniformly colored line or area.
  • Using such areas results in a cost saving, since the inks of digital inkjet printers are usually a lot more expensive than the inks of rotogravure or offset printers.
  • Such areas are also of interest to allow for an automatic detection of the position of the predetermined patterns, for example for cutting up the laminate board automatically.
  • Such areas especially when present as a stretched area extending over the entirety of the length or the width of the paper, enables to use several digital printers in the zones delimited by such areas, without having to worry about the seamless merging of patterns printed by several digital printers.
  • the printed paper sheet of the invention is preferably used for the manufacture of furniture panels. Especially for furniture the need to custom design individual decorative panels is high.
  • the invention also concerns a decorative panel, wherein said panel at least comprises a substrate and an attached thereto decor layer having a digitally printed pattern, with as a characteristic that said decor layer consists of a predetermined portion of a printed paper sheet carrying the digitally printed pattern of a plurality of such panels.
  • the decor layer is attached to the substrate using the so-called DPL process, wherein the paper sheet is provided with a thermosetting resin, such as with melamine formaldehyde, and attached to the substrate by using a heated press treatment, resulting in said adherence, as well as in a hardening of the available resin.
  • a thermosetting resin results in a fairly scratch resistant surface.
  • the paper sheet has been provided with an amount of resin, prior to it being printed.
  • Such an embodiment leads to a more stable printed paper sheet, and attaining a relief corresponding to the print in the surface of the decorative panel can be more straightforward. Furthermore, impregnation of the paper sheet with resin, before or after printing, reduces the risk that splitting of the paper occurs while sawing up the decorative laminated board.
  • the invention also concerns an item of furniture, with as a characteristic that said item of furniture comprises a plurality of such decorative panels, wherein the decor layer of each of said plurality of decorative panels consists of a predetermined portion of the same printed paper sheet.
  • said item of furniture comprises a plurality of such decorative panels, wherein the decor layer of each of said plurality of decorative panels consists of a predetermined portion of the same printed paper sheet.
  • the present invention lays open the possibility of using only one or a limited number of structured press elements per furniture item, while still allowing for a panel adapted design of the relief, even when different sizes of decorative panels are comprised in the furniture item.
  • the invention makes it possible to create a press element that comprises the structure of two or more differently sized panels, and thereby creates a smaller required minimum batch size of furniture items to justify the production of an expensive press element.
  • a press element may be designed that corresponds with several differently printed paper sheets.
  • the layout i.e. the position of the differently sized predetermined portions, is maintained in the paper sheet.
  • the press element may be designed to impress the edges of one or more depicted wood parts and to provide the wood part itself with a randomly distributed wood grain structure.
  • the depicted wood parts may have a varying design from paper sheet to paper sheet, and still the press element will be able to press down the edges of the wood parts.
  • only the tint or basic color of the printed pattern is changed form paper sheet to paper sheet.
  • the press element is also able to provide wood graining and/or impressed edges in correspondence with the different printed patterns.
  • the above two examples are in first instance important when several furniture items produced in the same way are expected to become installed together. For example in the case of kitchen cabinets, it is better avoided to have identical printed design on neighbouring cupboards in order to prevent a fake look of the kitchen.
  • the invention concerns also a method for manufacturing an item of furniture, wherein the item of furniture is assembled from a plurality of decorative panels, at least comprising a substrate and a decor layer with a digitally printed pattern, with as a characteristic that the pattern of said plurality of decorative panels is printed on the same paper sheet by means of one or more digital printers.
  • a digital printer Preferably use is made of one or more single pass or multi pass printers.
  • the abovementioned stretched unprinted areas are put into practice, e.g. to form an interstice between the printed areas of the respective printers.
  • such unprinted area resolves any issues relating to invisibly stitching the printed areas of the respective printers together.
  • the present invention allows for an assembly of two or more printers of limited width to together make up for the total width of the paper sheet to be printed.
  • a possible visible stitch can be positioned in the aforementioned unprinted area or interstice. E.g one could work with two or more single pass printing engines positioned next to each other, with or without overlap, in the width direction of the paper sheet, or roll as the case may be, without having to worry about blending the respective printed areas into each other.
  • pigment containing inks such as a UV curable ink
  • pigment containing inks warrant a good resistivity against degradation under UV radiation, such as under sunlight.
  • the present invention completely reverses the design of decorative panels and items of furniture. Indeed, in accordance with the prior art, the design of furniture was independent from the decorative laminate board. Decorative panels were simply cut out of such laminate board and the item of furniture was assembled.
  • the present invention links the design with the layout of the print on the decorative laminate board. Indeed before digitally printing the paper sheet of the invention the design of the item of furniture should already be known, since the print features predetermined portions for these panels.
  • the digital design of the printed pattern of the laminate board is preferably also used to cut it up into the plurality of decorative panels, although an intelligent saw might use cameras and other sensors to identify the position of said predetermined portions.
  • the decorative panels of the invention preferably comprise a wood based substrate, such as an MDF or HDF substrate (Medium of High Density Fiberboard) or a substrate consisting of or essentially made of wood particleboard or plywood.
  • a wood based substrate such as an MDF or HDF substrate (Medium of High Density Fiberboard) or a substrate consisting of or essentially made of wood particleboard or plywood.
  • paper sheets as mentioned above may be part of a roll or continuous web of paper prior to, during, or even after printing.
  • the paper sheet of the invention may comprise unprinted areas which are predetermined for white or uniformly colored decorative panels.
  • the front of the door comprises a digitally printed pattern, while the panels making up for the carcass of the cabinet may be white or uniformly colored.
  • the laminated board of the invention may comprise a decorative pattern at a side opposite the digitally printed pattern.
  • This may be a similarly printed paper sheet, or, even more preferably, a dyed paper or a conventionally printed paper, such as a paper printed with a continuous pattern and e.g. having a repeat in the length direction of less than 1,5 meters.
  • the paper sheet attached to this side is preferably also treated with thermosetting resin and adhered to the laminated board with the same press treatment as said digitally printed paper sheet.
  • the decorative panels obtained from such board will then preferably be positioned with their digitally printed pattern directed to the outside of the furniture item, while the side comprising the dyed or conventionally printed paper is directed to the inside of the furniture item.
  • the figure represents a printed paper sheet 1 for manufacturing decorative panels.
  • the paper sheet 1 carries the digitally printed pattern 2A-2B-2C-2D-2E-2F of a plurality of such panels, in this case of six panels, wherein the panels have at least two, in this case three different sizes.
  • Predetermined portions 3A-3B-3C-3D-3E-3F, in this case distinct portions, of the paper sheet 1 comprise the digitally printed patterns 2A-2B-2C-2D-2E-2F of the six respective decorative panels, in this case furniture panels.
