Definitions

  • a digitally printed product a method for manufacturing the same and its use
  • the invention relates to a digitally printed product, a method of manufacturing the product and the use of the product.
  • the invention concerns relatively large-area plate-like products, which are suitable for wall elements, billboards or the like, or to the coating of such walls and the like, the products preferably being sufficiently weather-resistant to be suited to outdoor use.
  • a general advantage of digital printing is the possibility to quickly change the printing (of text and/or figures) without interrupting the process, which is enabled by electric control and which results in short differentiated production runs and advantageous costs.
  • Fibre-based plates such as plywood, chipboard, fibre board, hardboard or OSB board, which are used as construction materials, are protected for outdoor use by coating them with a film impregnated with resin.
  • a conventional procedure is to absorb phenol-formaldehyde resin or amino resin into kraft paper, after which the paper is attached to a base board at a raised pressure and temperature/ the attachment being based on the hot curing of resin.
  • one or more thermoplastic layers are also possibly included in the protective coating.
  • prints are included in the coatings by printing the paper by flexographic printing before impregnating it with the resin.
  • the patent application Fl 20050172 discloses a coating, which is intended for wood panels, such as plywood or chipboard and which is based on kraft paper that is impregnated with a resin mixture.
  • the patent specification mentions the advantages and disadvantages related to the weather resistance of various types of res- ins; phenol-formaldehyde resins do not crack but they change their colour under the effect of sunlight and UV light, whereas amino resins have a good weather resistance but they are more susceptible to cracking.
  • the purpose of the specification is to provide a wood panel coating that has an even, light colour shade, whereby the darkening that the phenol-formaldehyde resins undergo, in particular, is considered a problem.
  • the specification discloses the pigmenting of the resin mixture and printing the kraft paper with a desired printing ink. The purpose of the colour printing is thus to provide a coating of an even colour and an even quality, which has good coverage.
  • the application Fl 20050172 mentions no digitally printed products or any prod- ucts that would contain information produced by printing.
  • the only goal of the colour printing disclosed is to provide the uniform and even, preferably light colour shade of the product.
  • the specification mentions the use of coloured decorative paper in the coating, but merely as an alternative to brown kraft paper, i.e., the goal also in this case is the desired colour shade of the paper, not information or a decorative patterning of the board product.
  • the problem that the invention seeks a solution to is thus to provide a digitally printed plate-like product, where the printing consists of image or text information or decorative patterning and which resists weather, i.e., sunlight, UV radiation and varying humidity, rain and changing temperatures well enough to be suitable for outdoor use.
  • the product according to the invention is characterized in that it comprises a plate-like base and a fibre-based film, which constitutes its coating and is impregnated with softened amino resin, and that the coated side of the product is provided with digital printing.
  • the invention is based on an observation, according to which the paper, which is impregnated with colourless amino resin and attached to the plate-like base by means of heat and pressure, can be digitally printed and, thereafter, subjected to a long-term effect of weather without the quality of the printing essentially weakening or with relatively minor changes in the quality of printing.
  • An advantage of amino resins compared with phenol-formaldehyde resins is their good resistance to UV radiation, i.e., that they do not darken under the effect of visible or UV light.
  • the mechanical strength of the resin is a less critical factor, e.g., in billboards and, according to the invention, the mechanical strength of amino resin is improved by mixing a softener with it.
  • Suitable well-known softeners include caprolactam, or- tho/para toluene sulfonamide (Ketjenflex), acetoguanamine, monoethylene glycol (MEG), diethylene glycol (DEG), polyethylene glycol (PEG), polyvinyl alcohol (PVA), polyacrylate, acrylic resin, phenol-formaldehyde resin and the like.
  • a small amount of phenol-formaldehyde resin as softener does not yet cause a significant darkening of the product.
  • Suitable amino resins include melamine-formaldehyde resin, urea-formaldehyde resin or a mixture thereof. Melamine-formaldehyde resin is preferable in outdoor use and urea-formaldehyde resin in indoor use.
  • the share of amino resin in the mixture is preferably about 60-95 weight-% and that of softener is preferably about 5-40 weight-%.
  • other additives such as stabilizers, UV absorbents, pigments, surfactants, moisteners, anti-foam agents and diluents can be added to the mixture in a total amount of about 0.1-10% of the weight of the mixture.
  • the product according to the invention can be coated in the manner described above and digitally printed either on one side only or both sides thereof.
  • the films that serve as coating on different sides of the product are most preferably similar to each other, and the prints of the different sides of the product can be mutually similar or different.
  • the adherence of printing ink to the surface of the product and the visual quality of the product depend, first of all, on the quality of the colour and the suitably even absorbance of the surface.
  • the adherence can be influenced by UV-hardening the ink.
  • the adherence can be sufficiently strong as such, but in some cases it is weaker, even so that the printing can be scratched off by a fingernail.
  • the problem can be eliminated by providing the digitally printed coated side of the product with a protective lacquering.
  • a colour pigment that dyes or shades the printing surface can be incorporated into the protective lacquer, naturally, so that the pigment does not cover the printing, however.
  • the protective lacquer also provides the printing surface with a good wear resistance.
  • the base which the film impregnated with the amino resin mixture is attached to, can in the product according to the invention comprise cardboard, corrugated board or a wood panel, such as plywood, block board, chipboard, fibre board, hardboard or OSB board (Oriented Strand Board).
  • the film coating of such boards is conventional technology as such.
  • the base can comprise glued laminated timber or machined solid wood, whereby the film impregnated with the amino resin mixture adheres to the wood as such.
  • wood that is coated with a film impregnated with amino resin mixture to be distinguished from wood panels made of pulp, which is included in the present invention, is not known from before.
  • the fibre-based film to be impregnated preferably comprises paper that mostly consists of chemical pulp.
  • bleached paper is preferable.
  • white paper that is impregnated with resin leaves the grains of the wood partially visible. If the product is lacquered, it can be shaded by pigmenting the lacquer, so that the grains of wood are still visible under the transparent film (the impregnated white paper).
  • the level of the film coverage can be adjusted with pigments that are added to the resin.
  • white pigment can be included in the impregnation resin to whiten the product.
  • the film can comprise non-woven material. Wood fibres can partially or fully be replaced with plastic or glass fibres.
  • the method according to the invention for manufacturing a digitally printed product described above is characterized in that (i) a fibre-based film is impregnated with softened amino resin, (ii) the impregnated film is attached to a plate-like base by hot curing to constitute the coating, and (iii) the coated side of the product is digitally printed.
  • UV-hardening printing inks can be used.
  • the printing method can be, e.g., the ink-jet printing known as such.
  • the invention comprises use of a digitally printed product described above or manufactured by the said method, when subjected to weather in outdoor locations, in particular.
  • the product can serve as a separate decorative panel, billboard or signboard that is attached, e.g., to a stand intended for the same, or the product can comprise an element of a building wall, fence, frame or scaffolding or the like.
  • the products according to the invention are also suitable for indoor use, e.g., on furniture and wall surfaces, wherein exposure to sunlight is possible and protection against light and UV light is thus desirable.
  • Suitable applications include external wall elements, interior walls, ceilings and floors of buildings, out- door advertisements on roadsides, bus stops, poster stands, lamp posts, in sports fields, in front of shops, noise barriers, garbage shelters, construction site fences, playground fittings, lorry platforms and other vehicles and means of transport.
  • the thicknesses of the reference plywood boards were 4 mm and 9 mm.
  • the plywood boards were coated with commercial impregnate films 60/174 Novox NW and 60/174 Novox OW (Laminating Papers Oy), which comprised kraft paper that was impregnated with a resin mixture, or they were left uncoated (reference boards).
  • 60/174 Novox NW 4.6% of Ti ⁇ 2 pigment that reflects UV radiation was added to the softened amino resin.
  • the impregnation resin in Novox OW was otherwise the same, except that there was only 0.7% of Ti ⁇ 2 pigment.
  • Coloured digital ink-jet printing was carried out on all boards, both protected at the edges and without protection. After printing, part of the boards were lacquered with gloss lacquer or dull lacquer, part was not lacquered.
  • the climate testing comprised a 1000-h testing of test samples in a climate chamber, where the following cycle was repeated:
  • test samples were photographed at the beginning of the test (series of images a and c) and after 1000 h from the beginning of the test (series of images b and d).
  • the images are attached to the present application.
  • Example 1 9 mm plywood + 60/174 Novox NW + printing + gloss lacquer
  • Fig. 1a a test sample without edge protection at the beginning of the test
  • Fig. 1b the test sample without edge protection after 1000 h
  • Fig. 1c a test sample with edge protection at the beginning of the test
  • Fig. 1d the test sample with edge protection after 1000 h.
  • Example 2 4-mm plywood + 60/174 Novox NW + printing
  • Fig. 2a a test sample without edge protection at the beginning of the test
  • Fig. 2b the test sample without edge protection after 1000 h

  • Fig. 2d the test sample with edge protection after 1000 h.
  • Fig. 3a a test sample without edge protection at the beginning of the test
  • Fig. 3b the test sample without edge protection after 1000 h
  • Fig. 3c a test sample with edge protection at the beginning of the test
  • Fig. 3d the test sample with edge protection after 1000 h.
  • the Novox OW film gives the plywood a weaker UV protection than the Novox NW film.
  • the film as such does not crack and the surface is smooth, but the OW film transmits UV radiation more easily than the Novox NW film, whereby the plywood darkens.
  • the OW film protects the plywood significantly against darkening and cracking compared with a case, where the plywood is merely lacquered. No rippling phenomenon occurs.
  • Example 4 9 mm plywood + 60/174 Novox OW + printing
  • Fig. 4a a test sample without edge protection at the beginning of the test
  • Fig. 4b the test sample without edge protection after 1000 h
  • Fig. 4c a test sample with edge protection at the beginning of the test
  • Fig. 4d the test sample with edge protection after 1000 h.
  • Example 3 A very transparent coating similar to Example 3, wherein the UV protection is weaker than the Novox NW films, the coating remains smooth and does not crack and no rippling phenomenon occurs.
  • the coating protects well the surface of the plywood but is poorer in preventing the effect of UV radiation that darkens the plywood. There is no great difference between the boards with or without edge protection.
  • the UV resistance of the ink on top of the coating is good.
