VDP Quality aspects on fibre based packaging : An elementary print quality study on corrugated board

• Variable data printing (VDP) is a technique whereby certain information can be altered in an otherwise static layout with the help of a digital printing system, and in the packaging industry a wide range of applications are possible. Inkjet printing, due to its non-impact printing (NIP) principle, is the most suitable technique to be implemented in packaging production (van Daele, 2005). Only when printing high volumes is inkjet printing much more expensive than conventional printing (Viström, et al., 2006). However, the advantages of inkjet printing could still be adopted by another approach.At Innventia AB, the “HybSpeed Printing” project was initiated to study the combination of a conventional printing process with inkjet printing. The aim of the project is to assess the practicability of attaining high quality VDP at high speed on a variety of packaging papers for corrugated board production. The exploratory trials were conducted on a Kodak Versamark DP5240 in Örnsköldsvik, Sweden, in cooperation with the Mid-Sweden University - Digital Printing Centre (DPC). Nine different substrates, white top and pure white liner, single-coated, double-coated, kraftliner and testliner were printed at a speed of 2 m/s.Rehberger et al. (2010) described in the first part of the study that high-speed inkjet printing at 5 m/s has only an insignificant influence on the print quality. In this article, the influence of paper properties is discussed and it is shown that the paper quality has a considerable influence on the print quality. All paper qualities led to an acceptable print result at a medium print resolution. Speed is the most important factor for inline implementation of inkjet, but the tests revealed that the paper properties are most decisive for good print quality.
