A Study of Mottled Images in an Intermediate Transfer Belt System
Abstract:Canon has developed a two-layered intermediate transfer belt (ITB) that reduces the density unevenness that causes mottled images, and introduced it on the LBP7200C color laser printer. One of the technical advantages of this ITB system is that it can support a variety of media including other than plain media. However, one of the major technical challenges in an ITB is mottled images, which are considered to be caused by unevenness in transfer efficiency in the secondary transfer process. This report explains the development of a tool for measuring toner adhesion force to an ITB after the primary transfer process, and the results of such measurements. Based on experiments and numerical simulation of the secondary transfer process, the reduction of mottled images in a two-layered ITB by low toner adhesion force is also discussed.

For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
