We are happy to inform that the abstract submitted by CP7 researcher Ludovic Gustafsson Coppel has been accepted for an oral presentation at the quadrennial Session of the international Commission on illumination (CIE). The paper, Perception of whiteness difference under different illuminations, focuses on one important colour in printing, namely white.
Ludovic Gustafsson Coppel is currently member of the technical committee TC 1-77 on whiteness. He his also the Swedish representative at CIE Division 1 (Vision and Colour). For this conference, he was awarded a travel grant from the Swedish Graphic Companies’ Federation.
Two new Early Stage Researchers Jana Blahová and Irina Mihaela Ciortan are recruited at VoxVil AB, Sweden and Gjøvik University College, Norway for a 6 months period starting in March 2015. Jana will be working at VoxVil AB, Sweden mainly on the topic of ‘Applying spectral colour transfer functions on a 12-channel printing system’ with a focus on improving the performance of existing methods. Irina will be working at Gjøvik University College, Norway on the topic of ‘Spectral reproduction of Paintings‘.
The CP7.0 Project consortium welcomes Jana and Irina.
A workshop called ‘Next Generation Color Printing Workshop’ was organised at part of planned networking and dissemination activity by the project researchers and consortium in the CIC22 conference held at Boston, MA on November 3-7, 2014. For more details please click here.
Steven successfully completed his employment as an Experienced Researcher (ER1) at TUD, Darmstadt, Germany.
CP7 researcher Steven Le Moan successfully completes his role as Experienced Research (ER1) in the CP7 project. For more information on the research and work done by Steven as an experienced researcher in the CP7 project please click here. Steven is now employed at The Norwegian Colour and Visual Computing Laboratory, Gjøvik University College, Gjøvik, Norway as a post doctoral researcher in the HyperCept project.
The sixth training event (TE6) was held at Océ Print Logic Technologies SA, France , on October 23 – 27, 2014. The event was attended by all the research fellows as part of the training program in the CP7.0 project. The event at Océ Print Logic Technologies SA was focused on lectures and discussions from key staff at Océ about, business models and their relation to research, case studies related to 2.5D printing and 3D printing technology, its pros and cons and intellectual property rights related to these technologies.

In September, CP7 researcher Ludovic Gustafsson Coppel from Gjøvik University College visited the University of the West of England, Bristol, and Fraunhofer Institute for Computer Graphics Research IGD, Darmstadt, as part of his secondments. The aim of the visit was to model the light reflection from layered materials in two different applications: multi-layered coloured prints with inkjet printer to improve colour output of original artwork (in collaboration with ESR Melissa Olen in Bristol) and colour management in 3D colour printing.
CP7 researchers Ludovic Gustafsson Coppel and Paula Žitinski Elías have recently returned from the Advances in Printing and Media Technology conference (IARIGAI) in Swansea, Wales. Paula presented a paper about multilevel halftoning. The second paper deals with spectral colour prediction of halftone prints using probabilistic models. The third paper shows the feasibility of spectral proofing (i.e. reproducing the appearance of spot colours in multiple illuminants) with a multi-channel printer and is a collaboration with CP7 researcher Radovan Slavuj and Steven Le Moan.

- Next generation printing – Towards spectral proofing, by Coppel, L.G.; Le Moan, S.; Slavuj, R.; Elías, P.Ž. and Hardeberg, J.Y.
- Multilevel halftoning applied to monochromatic inks in multi-channel printing, by Elías, P.Ž.; Gooran, S. and Nyström, D.
CP7 researcher Radovan Slavuj had a successful pre-defence on September 18, 2014 at Gjøvik. There, all the work that has been done around printer modeling and halftoning was presented and future directions were suggested and discussed. The Pre-Defense had concept of a real defense with two opponents, supervisors and audience who were free to ask questions. Title “Spectral Colour Reproduction with Multichannel printers” represent work that has been done until now, but do not necessarily absorbs all material from final thesis. Overall, the timing to conduct Pre-Defence was right as there is one more year left for Radovan to make the thesis more unique and that significant contribution could be made in the field.
Early September, CP7 researcher Teun Baar from Océ Print Logic Technologies visited the University of the West of England as part of his secondment. During the secondment, relief stamps were made for the application of relief printing. The stamps were created using 3D printers and wood engraving machines. The aim of the research was to compare the limitations and advantages of each of the processes and suitability to creating Chiaroscuro relief prints.
