Abstract

Panels having a decorative surface may include a substrate and a top layer, and the top layer may include a paper layer having a printed pattern. A method for manufacturing such panels may involve providing the paper layer with a treatment that includes providing the paper layer with an ink receiving substance, and providing the treated paper layer with at least a portion of the printed pattern. The printed paper layer may be provided with thermosetting resin. Providing the portion of the printed pattern may involve depositing pigment containing inks on the treated paper layer using a digital inkjet printer. The printed pattern may be provided in a single continuous relative movement of the paper layer with respect to the digital inkjet printer. The pigments may be color pigments. The digital inkjet printer may include print heads with nozzles for firing droplets of the pigment containing inks onto the treated paper layer. The pigment containing inks may include a water vehicle that maintains a contact angle, at the interface between the droplets of pigment containing ink and the treated paper layer, between 0° and 90°. The contact angle may be measured between the droplets and the treated paper layer. The droplets may have a volume of 15 picoliters or less. A definition of at least 200 dpi may be attained in the portion of the printed pattern.
