A method of manufacturing a floor board comprises the steps of supplying a panel, printing a curable substance or surface removing substance onto the panel in a predefined pattern for creating an elevation on the panel at the pattern or removing a portion of the surface of the panel at the pattern, respectively, and curing the curable substance or removing any reaction products of the surface removing substance and the panel.

A printing apparatus includes, an outer jig comprising an outer wall portion and a recessed portion, an inner jig disposed in the recessed portion and forming a hole between the outer wall portion and the inner jig, and a print head comprising a pad portion configured to overlap the hole, wherein the outer jig comprises an outer coupling portion disposed adjacent to a first surface of the outer jig facing the inner jig, the inner jig comprises an inner coupling portion disposed adjacent to a second surface of the inner jig facing the outer jig, and the outer jig and the inner jig are detachable from each other by detachment of the outer coupling portion and the inner coupling portion from each other.

A method of printing on workpieces comprising placing a workpiece in one of a plurality of holders provided spaced apart on a conveyer and moving the holders forward. The method comprises obtaining a first image of the workpiece in the holder, the first printing station comprising a printing head adjustable relative to the conveyer, and determining, based on the first image, the actual position of the workpiece in the holder. Further, the method comprises calculating a printing position of the printing head relative to the holder for positioning the print in a predetermined desired position on the workpiece, based on the predetermined desired position of the print on the workpiece and the determined actual position of the workpiece in the holder. The method also comprises adjusting the position of the printing head to the calculated printing position and printing a print on the workpiece.
