Understanding Post Finishing Performance of Xerographic Prints
Abstract:Xerographic digital presses have been used for the production of a variety of publications. Some of these applications may employ hot melt adhesives or pressure sensitive adhesives. However, good adhesion can be hard to achieve with xerographic prints due to the presence of residual fuser release agents on the surface of prints. Also this adhesion problem is very complex since the release agent and paper coating chemistries, fusing process, post-finishing materials and processes are all involved. Thus, it is important to understand the chemistry of release reagent and the surface topography and chemistry of substrates as well as the interaction between them. A method to predict the general adhesion properties of the xerographic prints and their behavior towards finishing operations was developed. It was found that the residual oil on the surface of the prints affects the finishing performance. When the surface coverage of oil is above a certain threshold, post finishing problems appear. The surface coverage of oil depends not only on the oil rate per copy but also on the molecular structure of the oil as well as the substrates.

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.
