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. The pigment containing inks may be water-based. 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. The paper layer may be a colored base paper, a pigmented base paper, and/or a dyed base paper.
