Resumé: The aim of this research is optimization of print quality with the focus on multi-channel image reproduction and multi-layer relief printing. Hereby determining the benefits and drawbacks of using more than the conventional CMYK channels for colour printing. This research, on investigating opportunities for multichannel printing, at Océ Print Logic Technologies will be in close collaboration with the European project of Colour Printing 7.0. The project can roughly be divided in two areas: 1. Use of extra colourants: extra colourants can be added to the CMYK printing system with the purpose of minimizing colour mismatches and increasing the achievable colour gamut (as the example of the Canon 12-color LUCIA pigment ink system). Additionally, including channels like varnish or fluorescent inks provide the ability to locally enhance the image and create new market opportunities. 2. Relief printing: relief can be added to the prints by printing multiple layers of ink at given locations. With this technique, relief can be added to prints, with the purpose of creating texture or to create desired views from different viewing angles or lighting directions. Additional channels of ink in multi-layer printing, create a focus on aspects such as improving the print quality, reducing the print costs and discovering new market opportunities. The combination of these fields of study will allow to print objects in relief that closely resemble the original. Now with the full spectrum of colours available even for different lighting conditions, local varnish/reflection and precise depth of the paint strikes in fine artwork can be reproduced.
