Present Status of Liquid Toner Development Technology and the Problems to be Solved
Abstract:The present technical status of liquid toner development and a view of possible improvements are discussed. Liquid toner development is an ideal process for getting a precise image in high quality continuous tone printing. This process has also several weak points that currently prevent its universal use. In this paper, the variations in system configuration and materials are reviewed. The merits and demerits of liquid toner development are summarized, and then an overview about how to eliminate these barriers and emphasize its merits is shown. The discussion includes optical density, development speed, stability, handling, and the potential problem of pollution. In the discussion on optical density, it is indicated that the roughness of developed toner image surface should be improved because the scattering of light from this rough surface is considered to be one of the key reasons for its low optical density. The point is made that new materials should be tried as solvents and new structures of development station should be proposed to strongly advance liquid toner development.

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.
