Abstract
A method for manufacturing decorative panels includes rendering a wood pattern on a paper with a marking device to form a decorative layer before resin impregnation and heat pressing, wherein the marking device includes M inks and N inkjet printhead units. The rendering is performed in a plurality of passes in which each inkjet printhead unit includes the M inks, and the rendering step includes generating N sub-images in which an intensity of each pixel in the wood pattern equals the sum of intensities of corresponding pixels from the N sub-images, and the intensity of a pixel from a first sub-image from the N sub-images is a first percentage between 1 and 99 of the intensity of corresponding pixel in the wood pattern, and the intensity of a corresponding pixel from a second sub-image from the N sub-images is a second percentage between 1 and 99 of the intensity of corresponding pixel in the wood pattern.
