  • the present invention concerns a method for manufacturing decorative substrates, notably panels and boards, in particular based on wood fibers or mineral fibers such as wood particles boards, MDF (Medium Density Fiberboard) or HDF (High Density Fiberboard) substrates on which a decor is formed by digital printing.

  • Digital printing refers to methods of printing from a digital based image directly to the substrate. It usually refers to professional printing where small run jobs from desktop publishing and other digital sources are printed using large format and/or high volume laser or inkjet printers. Digital printing has a higher cost per printed object than traditional offset printing methods but this price is usually offset by the cost saving achieved by avoiding all the technical steps in between needed to make printing plates. It also allows for on demand printing, short turn around, and even a modification of the image with each printed copy. The savings in labour and the increased capability of digital presses means digital printing is reaching a point where it could match or supersede offset printing technology's ability to produce larger print runs of several thousand copies at a low price.
  • the decor is generally still printed on a separate support of paper or fleece which is applied onto the substrate.
  • a basic layer may be applied in order to ensure sufficient adherence of the applied inks, such basic layers may affect the printing quality.
