Embodiment Construction

[0106] Figure 2a-2d An embodiment of the invention based on a first principle is shown, wherein a bonding agent pattern BP or image is digitally formed by a digital applicator head spraying a bonding agent 11 in the form of a liquid substance. Digital printing heads or digital inkjet heads which are mainly used for the application of liquid substances without any colorants and which are not intended to print colored images are referred to below as "digital application heads". Pigment 12 is randomly scattered over the entire binder pattern BP by the second device. The binder binds some of the pigments to form the same pattern as the binder, while other unbound pigments are removed.

[0107] This two-step process, in which the pigment and liquid binder are applied separately, provides images with the same quality as traditional digital printing techniques. This method is particularly suitable where relatively large quantities of paint have to be applied to large-scale flat pa...

Abstract

The present invention relates to a method and apparatus for forming a digital image on a surface by applying to a surface a layer of powder comprising colored pigments; binding a portion of said powder and removing unbound powder from the surface.

Description

technical field [0001] The present invention relates generally to the field of digitally formed decorative surfaces, especially building panels such as floor and wall panels. The present invention relates to methods and apparatus for producing such decorative surfaces. [0002] Application field [0003] Embodiments of the present 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-resistant structural layer above the decorative layer. Accordingly, the following description of the technology, problems with the known technology, and objects and features of various embodiments of the invention will be directed, as non-limiting examples, to this field of application and in particular to conventional laminate flooring or Floors with a resilient surface layer are described. [0004] It should be emphasized that the various embodiments of the present invention may be used ...
