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.
CP7 researcher Sepideh Samadzadegan from TUD, Darmstadt visited Océ Print Logic Technologies SA in July, 2014 on 2 weeks secondment with the aim of collaborating with ESR 6 and scitentist-in-charge Maria V. Ortiz Segovia to Control colour-printed gloss by varnish-halftones. Sepideh’s research involves spectral gamut mapping which could be more complicated when another attribute such as “gloss” is considered along with the process inks. During the secondment Sepideh focused on printing colour-printed gloss to investigate the colour-gloss relation by conducting psychophysical experiments.
We are happy to inform that 3 papers submitted by the CP7 researchers are accepted at CIC 2014 for oral presentation. For more details please click here.
CP7.0 project presentation and participation at the Graphic Arts Special Interest Group meeting in Heidelberg, Germany.
CP7.0 researcher Steven Le Moan presented the project status and results at the ICC’s Graphic Arts Special Interest Group meeting held in Heidelberg, Germany on June 24, 2014. His presentation was a follow-up dissemination activity from last years presentation at the Graphic Arts Color Experts’ Day organised by ICC at Frankfurt, Germany in June 2013. For more details please click here.
We are happy to inform that the abstract submitted by CP7 researcher Melissa Olen has been accepted for an oral presentation at the Image Conference 2014 in Berlin, Germany. This oral presentation will provide Melissa with an opportunity to submit a full paper to their journal “The International Journal of the Image” which is a peer reviewed journal.
On Thursday June 26, 2014, CP7 researcher Teun Baar presented his ‘thesis in five minutes’ at his university Télécom ParisTech. The presentation was an exercise to present the context and the core of his thesis, in a 5 minute PhD pitch format. Teun decided to present his thesis in French, as an extra exercise to present in the language he became more familiar with during his recent work in France and to get more familiar with the French vocabulary concerning his thesis project. The presentation was received well with compliments for the clarity and the French. The video of the interview can be watched on the Teun’s private youtube page or on his linked in page.
The fifth training event (TE5) was held at the University of the West of England, Bristol, UK and the National Gallery, London, UK, on April-May (27 – 2) 2014. The event was attended by all the research fellows as part of the training program in the CP7.0 project.
The training focused on exploring beyond the boundaries of the current state of digital printing and colour management, with emphasis on print application and knowledge transferability between the arts and sciences. For more details please click here.
