Current research projects (in the field "print finishing")

Foundations for the standardization of abrasion tests on printed samples

Timescale: 01.06.2014 to 31.05.2016
Programme of the Federal Ministry of Economics and Energy for the support of “Industrielle Gemeinschaftsforschung (IGF)” via the German Federation of Industrial Research Associations (AiF)
Partner: Papiertechnische Stiftung (PTS), Heidenau

This project should lay the foundations for the revision of an abrasion test standard (ISO 18947), which has been developed by ISO TC 42 (photography) for photobooks and photos produced by digital and analogue means. It consists of two parts, one scientific, the other devoted to standardization. The Papiertechnische Stiftung [Paper Technical Institute] has been secured as a partner, which means that a controlled climate chamber and enhanced analytical equipment are available. The objective of the project is to transfer the standard from the field of digital photography to printed products in general. Besides the “Sutherland” abrasion testing device that is implicitly favoured in ISO 18947, the intention in this project is to also use the prüfbau “Quartant”, the IGT “RT 4” and the James Heal “Martindale” devices to test samples printed by means of various different printing methods with a view to reaching conclusions about the comparability of devices, repeatability and precision. The factors influencing the results of the tests will be investigated for all the devices. Besides developing the methodology, the influences exerted by materials (wax content of inks, stickiness of the dry ink film, proportion of crosslinking binding agent in the ink film, surface topography of the paper and print, surface elasticity of the paper and print and pore volumes of the paper and print) on sheet-fed offset printed samples will also be investigated.


Use of the laser engraving process for spine and material preparation in the industrial bookbindery

Timescale: 01.11.2012 to 30.10.2014
Programme of the Federal Ministry of Economics and Energy for the support of “Industrielle Gemeinschaftsforschung (IGF)” via the German Federation of Industrial Research Associations (AiF)

The purpose of this investigation is to look at the use of laser engraving to solve existing problems with various adhesive procedures in industrial bookbinding. Firstly, laser engraving is a non-contact process with great potential for releasing the fibres of difficult papers when preparing spines, whereas, despite their advanced state of development, the rotary tools used by almost all perfect binders continue to experience basic problems with releasing fibres. Secondly, the process can be used to remove and roughen up layers that jeopardize adhesion and cohesion (ink, varnish, paper coating) in order to prepare for gluing. Important objectives for the research project to investigate are increases in adhesion when producing perfect bindings, when gluing thread stitched book blocks and when side gluing softcovers.

This should make it possible for bookbinding companies to adopt measures to increase and ensure quality when dealing with problematic upstream products and to handle difficult product concepts. Given that industrial bookbinding needs to adjust to a sustained trend to difficult to process papers resulting from the wide variety of paper grades, inks and coating systems to be found in the market, this is something that is important. The binding of papers with multiple coating layers that have been printed with heavy applications of ink and full surface coated, high grammage papers has now become an everyday requirement. Additionally, the constantly increasing market share of digitally printed products and the variety of materials and the new requirements associated with these makes this an even more important challenge.
