Océ's Mono Component, Magnetic, Conductive Colour Toner
Abstract:Océ's Direct Imaging (DI) technology is a unique 7 colour dry-toner based printing process. The printing process is controlled by a subtle interplay between a magnetic force and an electrical force exerted on the inductively charged toner particles. Océ's DI technology therefore requires magnetizable and conductive colour toners.
A major challenge was to develop colour toners that yield a sufficiently large colour gamut. Carbonyl iron has been chosen as a magnetic pigment. For a conductive coating on the toner particles fluorine doped tinoxide (FTO) is used.
The FTO coating on the toner particles is completely transparent and colourless. The carbonyl iron pigment in the toner however still absorbs a significant fraction of the incident light. By using fluorescent mixtures of dyes, in addition to colour pigments, we have succeeded in attaining vivid colours and a large colour gamut.

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.
