Abstract:
The present invention relates to a method for printing wood-based boards, in particular, wood-fiber boards, by means of a digital printing process. The method includes the steps of: a) measuring the color value of the wood-based board of at least one first batch and transmitting the color values to a computer program; b) measuring of the color values of the wood-based board of at least one further batch and transmitting the color values to the computer program; c) processing the color values of the wood-based board of the at least one further batch in the computer program and adapting the color value of the digital print; and d) printing at least one side of the wood-based board by means of digital printing technique by forming a décor layer such that no color deviations between the printed decors of the wood-based boards of the at least one first batch and each further batch occur.
Abstract:
Disclosed is a method for printing wood material boards. The method includes: by a digital printing process, measuring color values of the wood material boards from at least one first batch and forwarding the color values to a computer program; measuring color values of the wood material boards from at least one further batch and forwarding the color values to the computer program; processing the color values of the wood material boards from the at least one further batch in the computer program and adapting the color values of the digital print; and printing at least one side of the wood material boards by means of digital printing technology, forming a decorative layer in such a way that no color deviations occur between the printed decorations of the wood material boards.
Abstract:
Disclosed is a method for printing a wood material board, in particular a wood fiber material board, by means of a digital printing process. The method includes the steps of (a) printing at least one side of a wood material board by means of digital printing technology, forming a decorative layer; (b) applying a protective layer containing at least one resin, at least one radiation-curable varnish and/or at least one polyurethane to the decorative layer of the wood material board; and (c) pre-drying and/or pre-gelling the protective layer applied to the decorative layer of the wood material board.
Abstract:
A method for producing a wood-fiber board, which has a pattern on the top, in that glued wood fibers are scattered at least one layer to form a fiber cake, and the fiber cake is subsequently compressed under pressure and temperature to form a board of the desired thickness, is characterized in that the pattern is applied to the fiber cake before compression. An installation for producing a wood-fiber board with a scattering device, by means of which a fiber cake comprising at least one layer of wood fibers glued with resin is scattered, and a conveyor device, which conveys the fiber cake in a process direction to a pressing device in which the fiber cake is pressed to form a board of the desired thickness, is characterized in that a printing device is arranged above the conveyor device between the scattering device and the pressing device.
