  • Publication number: 20160347085
    Abstract: A method for manufacturing decorative workpieces includes the step of nesting a set of decorative patterns digitally printed on a decoration layer to reduce the waste of decoration layer. To perform a corresponding relief for the nested decorative patterns on a nested decorative workpiece, the relief provided by a digital relief apparatus is in a correct match with the nested decorative workpiece. If the printing zone of the digital printer has a failure zone, the nesting method prevents arranging of the decorative patterns in this failure zone.

  • Patent number: 8960121
    Abstract: A relief print master is created by a printhead that moves in a slow scan direction. The nozzles of the printhead jet droplets of a polymerisable liquid on a rotating drum. The different nozzles jet droplets simultaneously on different layers that have different diameters. As a result, the droplets jetted by different nozzles travel over different distances before landing. The effect of this is that the droplets undergo different position lag as they land on the different layers. By rotating the printhead in a plane that is orthogonal to the jetting direction this effect can be compensated for.
