Abstract

This invention concerns vision control panels and a method of UV inkjet printing vision control panels. A substantially imperforate light permeable material is partially printed with a ‘print pattern’ comprising a base layer and a design layer comprising a design colour layer. The method is limited to digital UV inkjet printing of all the superimposed layers required to make such panels. Optionally, the method uses a novel printhead array with a novel order of ink color supply and/or novel software to enable the required build-up of ink layers, for example of black, optional silver, white, cyan, magenta, yellow and process black colors. Printing is preferably arranged so that the base layer and design color layer are printed in the minimum number of passes of the printhead assembly of the digital UV inkjet printer to achieve the desired effect, preferably in one pass of the printhead assembly.
