Print Quality in Contact and Non-Contact Fixing
Abstract:In office printers hot roller fusing is favored, whereas non-contact fixing methods are used especially in web printing. The aim of this study was to find out whether there are differences in quality-forming characteristics between contact and non-contact fixing.
Unfused print areas were fixed with a detached hot roller fuser, IR radiation or with a hybrid of these two. The fixing energy was varied with the temperature and fixing time. In addition to basic quality measurements, the micro-scale quality was measured with a multigeometrical optical testing device, which allows different quality variables to be measured from exactly the same spot. Text quality was measured with a scanner-based system. This paper presents the data and discusses the results from the viewpoint of the mechanisms behind fixing quality.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
