Colour Printing 7.0: Next Generation Multi-Channel Printing (CP7.0) is a training and research project funded under the Marie Skłodowska-Curie Initial Training Networks (MCITN) call in EU's seventh framework programme (FP7). The project is led by Gjøvik University College in collaboration with five full network partners and six associated partners from academia and industry. The project addresses a significant need for research, training and innovation in the printing industry. The main objectives of this project are to train a new generation of printing scientists who will be able to assume science and technology leadership in this established technological sector, and to do research in the colour printing field by fully exploring the possibilities of using more than the conventional CMYK inks. The research focuses particularly on spectral reproduction (new spectral colour modelling, spectral gamut mapping, halftoning and image quality assessment) and on multilayering printing methods to control ink mixing, relief (2.5 D prints) and surface properties. This paper reviews the achievements of the project so far in conjunction with a topical workshop at the 22nd Colour and Imaging Conference on “Next generation colour printing”.
