Fuser Roll Material Effects on Digital Print Quality
Abstract:Fuser roll materials play a dominant role on digital print quality. The type of fuser roll coating, thickness of the coating, surface finish (texture), filler materials, back-up pressure roll material, shore A durometer of the rubber and printer speed are some of the factors which influence the final output print quality. Silicone rubber rollers by virtue of their compliancy produce an acceptable print quality, matt finish images and good fuse grade. These rolls are often registering a poor roll life. Hard fuser rolls with a fluoropolymer coating does accomplish a good roll life, but often produces a poor mottled print (images). A hybrid roller which will capture the good attributes of the hard and soft rollers seems to be the ideal choice to accomplish the exceptional print quality and fuse grade requirements of digital printing.
An overview of fuser roll materials and their impact on digital printing will be discussed. The new hybrid roller is still evolutionary and its long- range implications need to be studied, one and may be the way of the future with the advent of higher speed printing as well as higher resolution of printing.

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.
