Abstract
A method is provided for manufacturing a paper layer having a printed pattern for use in panels that at least include a substrate and a top layer. The top layer includes the paper layer. The method may involve providing the paper layer with an inkjet receiver coating by transporting the paper layer relative to a coater in a coating direction. The coated paper layer may be provided with at least a portion of the printed pattern using a digital inkjet printer that includes a housing containing print heads. Providing the printed pattern may involve using water based pigment containing inks. The printed pattern may include a wood motif having wood nerves extending generally in a nerve direction substantially corresponding to the coating direction. Providing the printed pattern may involve a relative motion between the digital inkjet printer and the paper layer during a printing operation in a printing direction substantially corresponding or substantially opposite to the coating direction. The paper layer may be maintained flat inside the housing, or the minimum radius over which the paper layer is bent inside the housing may be larger than 25 centimeters. The paper layer may be fed fr…
