DIGITAL PRINT WITH WATER-BASED INK ON PANEL SURFACES

摘要

A water-based ink and a method to form a digital print with the water-based ink on a dense substrate including a polymer material or on surfaces that are heated and pressed after printing. The substrate is prior to the printing step preferably heated in order to prevent floating of the water-based ink drops.

主权项

1. A method of forming a building panel, wherein the method comprises:
heating a substrate to a temperature of at least about 80° C.; printing a digital image with a print head by applying drops of a water-based ink on the heated substrate, wherein the water-based ink comprising a colorant comprising an aqueous pigment dispersion, a binder comprising an acrylic resin dispersion, preferably a thermally crosslinkable acrylate copolymer dispersion, and a viscosity increasing substance comprising glycol or glycerine; applying a transparent wear resistant layer on the digital image; and connecting the substrate to a core with heat and pressure, thereby forming a building panel.
