Colorlab Workshop #4: Machine vision and color printing

The workshop is organized by The Norwegian Color Research Laboratory and takes place at Gjøvik University College (GUC), in room G302, on Thursday October 27th.

The workshop is free and open to all.

Program

* 10:30 - 11:30 Machine vision based quality control from pulping to paper making for printing , Prof. Heikki Kälviäinen, Lappeenranta University of Technology, Finland 

This presentation considers possibilities which machine vision can provide for quality control along the whole manufacturing line of paper and board products. The scope is from pulping to papermaking, mainly for printing. The motivation of this study comes from the necessity to predict the quality of printing on paper or board, especially in case of images. Printed materials should look good enough to a consumer; advertisement must obtain a positive attention and a high-quality journal must to be comfortable to read. Thus, a paper manufacturer should know which kind of quality it offers to a printing house. In this way the production is resource-efficient and environmentally sound, using less raw material, water, and energy. The visual quality assessment is usually done manually or semiautomatically either observing manufacturing processes or test prints. The results obtained from industrial research projects consist of off-line and on-line solutions for industrial manufacturing and laboratory level testing

* 11:30 - 12:30 Lunch  

* 12:30 - 13:30 Digital Printing - A Rich Domain for Image Analysis and Pattern Recognition , Prof. Jan Allebach, Purdue University, USA 

Printing ecosystems can be loosely divided into two groups: home/office printing and commercial/industrial printing. Home/office printing is characterized by usage models that are highly heterogeneous, consisting of many different relatively small jobs. Home/office printing only became possible with the advent of digital technologies during the 1980s. In contrast, commercial/industrial printing has been an established activity for nearly 500 years. But it is only now during the last decade or so experiencing a transformation to digital technologies. Digital image analysis and pattern recognition have important roles to play in both these ecosystems, starting with the development of the printing system, continuing to inspection during manufacturing, and then once the product is in use, enabling a more rewarding customer experience, and providing an autonomous or semi-autonomous capability to troubleshoot the causes of print quality issues. In this presentation, I will provide an overview of these application areas, illustrated by specific projects that have been conducted in our laboratory.

* 13:30 - 14:00 Discussion
