Colour Printing 7.0: Next Generation Multi-Channel Printing (CP7.0) is an Initial Training Network funded by EU’s Seventh Framework programme. 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 traditional technological sector, and to do research in the colour printing field by fully exploring the possibilities of using more than the conventional four colorants (CMYK) in printing; focusing particularly on the spectral properties. We primarily focus on four key areas of research; spectral modeling of the printer/ink/paper combination, spectral gamut prediction and gamut mapping, the effect of paper optics and surface properties on the colour reproduction of multi-channel devices, and optimal halftoning algorithms and tonal reproduction characteristics of multi-channel printing devices. Several application areas are considered, including textile and fine art.
In one part of the project, an extra dimension is added to the print in the form of relief, with the goal of controlling the angle-dependent reflection properties. For such prints, called 2.5D prints, a surface texture is created by printing multiple layers of ink on desired locations. The ongoing study will lead us to create prints with relief that closely resemble the original, with a focus on aspects such as improving the print quality, reducing the print costs and discovering new market opportunities.
In this presentation we will give an overview of the CP7.0 project, its goals, accomplishments and challenges. Furthermore as most if not all of the involved scientists-in-charge, postdoctoral researchers and PhD students will be present, it will be possible to go more in depth in the discussions following the talk.
