A method of manufacturing decorative panels comprising the steps of - rendering a wood pattern (W i,j) on a paper for forming a decorative layer wherein said paper has a paper weight between 50 g/m 2 and 130 g/m 2 and a porosity according to Gurley's method (DIN 53120) between 8 and 20 seconds and wherein the rendering is performed by a marking device in a plurality of passes (P 1..L); and wherein the marking device comprises M inks (I 1..M) and N inkjet printhead units (U 1..N); wherein each inkjet printhead unit (U i, i:1N) comprises the M inks (I 1..M); and wherein said M inks (I 1..M) are pigmented aqueous inkjet inks; - impregnating said decorative layer with a thermosetting resin; and - heatpressing said impregnated decorative layer together with a core layer for forming a decorative panel; and wherein the rendering step comprises: - generating N sub-images (S 1..N) wherein intensity of each pixel in the wood pattern (W i,j) equals the sum of intensities of corresponding pixels from the N sub-images (S 1..N); and wherein intensity of a pixel from a first sub-image from the N sub-images (S 1..N) is a first percentage between 1 and 99 of the intensity of corresponding pixel in the wood pattern (W i,j); and wherein intensity of corresponding pixel from a second sub-image from the N sub-images (S 1..N) is a second percentage between 1 and 99 of the intensity of corresponding pixel in the wood pattern (W i,j); and - halftoning each sub-image from the N sub-images (S 1..N), wherein minimum two sub-images are halftoned differently; and transferring each halftoned sub-image from the N halftoned sub-images to another inkjet printhead unit from the N inkjet printhead units (U 1..N) - jetting the N transferred halftoned sub-images during the plurality of passes (P 1..L) on said substrate. - rendering a wood pattern (W i,j) on a paper for forming a decorative layer wherein said paper has a paper weight between 50 g/m 2 and 130 g/m 2 and a porosity according to Gurley's method (DIN 53120) between 8 and 20 seconds and wherein the rendering is performed by a marking device in a plurality of passes (P 1..L); and wherein the marking device comprises M inks (I 1..M) and N inkjet printhead units (U 1..N); wherein each inkjet printhead unit (U i, i:1N) comprises the M inks (I 1..M); and wherein said M inks (I 1..M) are pigmented aqueous inkjet inks; - impregnating said decorative layer with a thermosetting resin; and - heatpressing said impregnated decorative layer together with a core layer for forming a decorative panel; and wherein the rendering step comprises: - generating N sub-images (S 1..N) wherein intensity of each pixel in the wood pattern (W i,j) equals the sum of intensities of corresponding pixels from the N sub-images (S 1..N); and wherein intensity of a pixel from a first sub-image from the N sub-images (S 1..N) is a first percentage between 1 and 99 of the intensity of corresponding pixel in the wood pattern (W i,j); and wherein intensity of corresponding pixel from a second sub-image from the N sub-images (S 1..N) is a second percentage between 1 and 99 of the intensity of corresponding pixel in the wood pattern (W i,j); and - halftoning each sub-image from the N sub-images (S 1..N), wherein minimum two sub-images are halftoned differently; and transferring each halftoned sub-image from the N halftoned sub-images to another inkjet printhead unit from the N inkjet printhead units (U 1..N) - jetting the N transferred halftoned sub-images during the plurality of passes (P 1..L) on said substrate. - generating N sub-images (S 1..N) wherein intensity of each pixel in the wood pattern (W i,j) equals the sum of intensities of corresponding pixels from the N sub-images (S 1..N); and wherein intensity of a pixel from a first sub-image from the N sub-images (S 1..N) is a first percentage between 1 and 99 of the intensity of corresponding pixel in the wood pattern (W i,j); and wherein intensity of corresponding pixel from a second sub-image from the N sub-images (S 1..N) is a second percentage between 1 and 99 of the intensity of corresponding pixel in the wood pattern (W i,j); and - halftoning each sub-image from the N sub-images (S 1..N), wherein minimum two sub-images are halftoned differently; and transferring each halftoned sub-image from the N halftoned sub-images to another inkjet printhead unit from the N inkjet printhead units (U 1..N) - jetting the N transferred halftoned sub-images during the plurality of passes (P 1..L) on said substrate.
