Abstract

A method for a printer (5) comprising a medium support surface (11) for supporting the print media, a print head assembly for ejecting colour inks (CMYKW) and varnish ink (V) forming a print on the print media and a print controller for controlling the printing of images on the print media in multiple layers. The print job comprises a colour image, a height image with height information per pixel of the colour image and a gloss image with gloss information per pixel of the colour image. The print head assembly subsequently prints the elevation layers, the anti-contouring layers, the white layers, the at least one colour ink layer and the at least one overcoat layer on the print media. The print controller creates multiple inverse anti-contouring layers, wherein each pixel value of the multiple inverse anti-contouring layers is a complementary value of the corresponding pixel in the anti-contouring layers with respect to a maximum of ink pixels determined to be printed on top of each other in the anti-contouring layers. The print head assembly prints the multiple inverse anti-contouring layers between the at least one colour ink layer and the at least one overcoat layer.
