Abstract

A method for a UV curable printer (5) comprising a medium support surface (11) for supporting the print media, a print head assembly for ejecting droplets of structure ink (S), white ink and coloured ink forming a relief print on the print media and a print controller for controlling the printing of the relief print in layers. Each layer is deposited in a predetermined plurality of passes of the print head assembly over the medium support surface. The print controller receives a print job comprising a colour image with colour information per pixel comprising a colour per pixel which is intended to be achieved by depositing the coloured ink, and a height image with height information per pixel comprising a height per pixel which is intended to be achieved by depositing a plurality of elevation layers of structure ink. The print controller determines besides the plurality of elevation layers at least one anti-contouring layer of structure ink to prevent contouring artefacts and at least coloured layer of coloured ink to form the colour image. The print head assembly subsequently prints the plurality of elevation layers, the at least one anti-contouring layer and the at least one colour layer. The print controller creating a last in time elevation layer intended to be printed in the predetermined plurality of passes, wherein the last in time elevation layer is formed by droplets of structure ink and white ink.
