Abstract: A method for manufacturing a paper layer having a printed pattern, to be used in the manufacturing of panels may involve providing the paper layer with a treatment, including providing the paper layer with an ink receiving substance. The treated paper layer may be provided with at least a portion of the printed pattern. Providing the portion of the printed pattern may involve depositing pigment containing inks on the treated paper layer using a digital inkjet printer. The pigment containing inks may be water-based. The digital inkjet printer may include print heads with nozzles. The depositing may involve firing droplets of pigment containing inks from the nozzles onto the treated paper layer. The paper layer may be fed from a roll, printed upon, and rolled back up again.

Abstract: Panels having a decorative surface may include a plate shaped 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, including providing the paper layer with an ink receiving substance. The treated paper layer may be provided with at least a portion of the printed pattern by depositing pigment containing inks using a digital inkjet printer of a single pass type. The printed pattern may have a definition of at least 200 dpi. The pigment containing inks may be water-based. The printed pattern may be a wood pattern. The pigment containing inks may include colored pigments and may comprise up to 8 different colors, including brownish and/or reddish colors. The digital inkjet printer may include print heads with nozzles for firing droplets of pigment containing inks onto the treated paper layer. The paper layer may be fed from a roll, printed upon, and rolled back up again. The paper layer, while printing, may be flexible and may be attached to the plate shaped substrate after printing. A layer of thermosetting resin may be applied above the paper layer and the printed pattern. Providing the layer of thermosetting resin may involve a press treatment.
