Training Event 2 : Paper properties and their influence on print result: What’s the difference between newsprint and inkjet photo paper

te2 swedenDates – 11 March 2013 till 15 March 2013

This training event covered the entire paper production process from pulping, paper machine, coating and finishing as well as the characterization of paper properties. The paper production process and paper characterization was covered both theoretically and practically by workshops at Metsa Board Husum paper mill and MoRe Research facilities. The event also included the ink and paper interaction for various printing technologies. Mechanisms for ink transfer, ink penetration and ink drying and their relation to ink and paper properties were explained.


• A visit to Metsa Board paper mill in Husum, Sweden was organised were paper production of coated as well as uncoated paper was introduced.

• A visit to MoRe Research lab was organised to learn about paper characterization and print evaluation.

This event laid the foundations for a 6 ECTS credits PhD course delivered by MIUN in Paper and Optics and Paper and Ink interaction. Detailed agenda of this training event can be found here.

Training Event 3

The third training event (TE3) will be organised at Linköpings Universitet, Campus Norrköping, Sweden in May 2013.

Training Event 3 : Digital Halftoning and Colour reproduction models

mail_image_previewDates – 27 May 2013 till 31 May 2013

Digital halftoning is an essential part of print reproduction, with a profound impact on the resulting print quality. In halftone prints on paper, physical and optical dot gains generally occur, making the print look darker than expected, and making the modeling of halftone reproduction a challenge. In this event, we aim to provide the fundamental knowledge about halftoning concepts and methodologies, as well as models predicting the spectral outcome of halftone prints. In order to provide a more thorough understanding of digital halftoning and colour reproduction models, the event will combine the theoretical content of the lectures with laboratory exercises.

The main topics include:

1. Basic Halftoning: where the students get familiar with different types of halftoning, and try a number of
well-known halftoning methods,

2. Advanced Halftoning and Quality Measures: Advanced halftoning methods, models for the eye, printer
models, and different objective quality measures are tested and examined.,

3. Dot Gain: Spectral measurements of halftone patches, how to use the measurements to calculate dot gain,
how to compensate a print for dot gain and different dot gain models are examined,

4. Dot Gain and Colour Reproduction Models: Dot gain for coloured inks, colour reproduction models and
colour differences are examined,

This event lays the foundations for a 5 ECTS credits PhD course delivered by LiU in Digital Halftoning and colour reproduction models. Detailed agenda of this training event can be found here.

Training Event 4

The fourth training event (TE4) was organised at Technische Universität Darmstadt, Germany on December 2 – 6, 2013.

Training Event 4 : Spectral reproduction workflow and spectral colour management

1_TE4-Fraunhofer IGD, Darmstadt, GermanyDates – December 2 – 6, 2013 

The spectral reproduction workflow gives an overview of the different steps in the reproduction of spectral data. The aim of this training event was

  • to give a detailed overview about gamut mapping, gamut mapping workflow in printing,
  • discussion and lectures on scientific writing,
  • lectures on spectral imaging workflow – state of the art, details, advantages and research opportunities compared to traditional printing

The research fellows took the opportunity to work with three different printing technologies: scene printing, offset printing and flexographic printing at this event. An industrial visit to Heidelberger Druckmaschinen AG at Wiesloch was organised to learn about manufacturing of high end offset printing machines.

Training Event 5

The fifth training event (TE5) was held at the University of the West of England, Bristol, UK and the National Gallery, London, UK, in April-May 2014.

Training Event 5: ‘N’ Colour Printing Beyond the Colour Gamut: New frontiers and solutions for professional colour management in digital printing.

OLYMPUS DIGITAL CAMERADates – 28 April 2014 till 2 May 2014

Held primarily at UWE, Bristol, this event 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. Divided into three key focuses, the first consisted of two days of presentations and activities relating to printmaking practices, from art historical processes through to current day digital technologies. This was complemented with presentations by invited speakers from industry and the arts community to emphasis their diverse considerations and approaches regarding their use of digital technology. The applications theme was capped off by a hands-on workshop where participants were invited to explore the possibilities current digital printing technologies offer for various novel applications.

The training event also offered a two day workshop on the theme of ‘maintaining momentum’. This covered a variety of topics relevant to PhD students currently in their middle years of study, including productivity, overcoming obstacles throughout the research process, presentation skills, and networking. Focusing heavily on engagement and delivery, it built upon the strong content based workshops hosted during previous training events.

The week was concluded with a trip to the National Gallery, London, hosted by the project’s associate partner. The tour offered a behind the scenes look into the various departments at the Gallery, introducing the participants to the range of carefully considered work that goes into retouching and restoration, research and analysis, photographic documentation and printed publicity, and curation of the Gallery’s collection. The tour exemplified the constructive collaborations between art and science that can lead to achieving mutually beneficial goals.

Training Event 6

The sixth training event (TE6) was held at Océ Print Logic Technologies SA, France , in October 2014.

Training Event 6: An industrial approach to colour and image processing for 2.5d/3d printing systems.
