We are happy to inform that the paper submitted by CP7 researcher Ludovic Coppel (written in collaboration with the associate partner Mid Sweden University) is now published in the Optics Express Journal. For more details please click here.
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.
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.

A special session was organised by the CP7.0 consortium in the MMRMA conference at Electronic Imaging 2014. Prof. Jon Yngve Hardeberg gave an invited talk on CP7.0 project goals, challenges and accomplishments. A total of 10 papers are published by the consortium (at the MMRMA conference) in EI2014. The details of the papers published and presented at EI2014 can be found here.
The fourth training event of the project was organised at TUD, Darmstadt, Germany on December 2 – 6, 2013. The event was attended by all the research fellows as part of the training program in the CP7.0 project.
The training covered the area of gamut mapping in the colour reproduction field along with spectral imaging workflow and traditional printing workflows in detail. To know more, please click here.
