Problems solved by technology

[0077] These methods are not suitable to be applied, for example, in wooden floors in which the protective layer is applied to a plurality of individual panels, and they cannot be used to provide a finished decoration or surface structure. Digital printing or digital embossing that is part and has to be adapted to the basic design and structure of each individual panel

example 1

[0163] Digital images are applied to the panels comprising high density fiber (HDF) boards. Images were generated using a single-pass printer comprising 5 stationary piezoelectric print heads. The inks are water-based inks containing colored pigments.

[0164] A piezoelectric print head with a drop size of 50 picoliters was used to apply a water-based UV-cured polyurethane clear layer equivalent to 10 g / m 2 film. The above materials are cured in a UV oven and a digital image with a digitally applied transparent layer can be obtained.

example 2

[0166] A digital image with a wood grain design was applied to the paneling comprising HDF boards. The image was generated using a single-pass printer comprising 5 stationary piezoelectric print heads. The inks used are water-based inks containing colored pigments.

[0167] A piezoelectric print head with a drop size of 50 picoliters was used to apply a water-based UV-cured polyurethane clear layer equivalent to 10 g / m 2 film. The above materials are cured in a UV oven.

[0168] Weight is 5g / m 2 Another similar transparent layer was applied using a piezoelectric print head with a droplet size of 50 μl. This layer is applied as a transparent image that coordinates with the digital image.

Abstract

The invention relates to building panels, especially floor panels and a method to produce such building panels that comprise a decorative surface and a transparent protective layer, which is applied by a digital coating. The invention describes a vision control system that may be used to adapt a digital print or a digital embossing to a specific panel surface.

Description

[0001] This application is a divisional application of Invention Patent Application No. 201380047467.5 with a filing date of July 10, 2013 and titled "Method for Applying Coating to Building Panels Using Digital Printing / Coating Technology". technical field [0002] The present invention relates generally to the field of panels, in particular floor and wall panels, having a decorative wear-resistant surface. The present invention relates to building panels with such a decorative surface and a manufacturing method for manufacturing such panels. [0003] Application field [0004] Embodiments of the invention are particularly suitable for application in floors that may be formed from floor panels comprising a core, a decorative layer and a transparent wear layer located above the decorative layer. Therefore, the following description of the technology, the problems of known systems and the objects and features of the invention will be made as non-limiting examples for this fiel...
