<title>Advances of magnetography in very-high-speed electronic printing</title>

Abstract

This paper provides an up-to-date status of the continuing effort at Bull to further improve the speed and productivity of magnetographic printing and explore new potential applications. Besides puting into perspective the whole research and development program in Very High Speed Magnetographics (VHSM), the paper deals more specifically with the design, construction and testing of full size, full function, prototypes of a Press Integrable Magnetographic (PIM) module. Major guidelines for the project have been: (1) consistent print quality at variable speed over a full range of speeds, (2) accomodation of high web tensions as may be required by a press, (3) printing process totally slaved to the paper web motion as imposed by press environment, (4) extended range of printing media. Development steps, technical approaches chosen and measured performances are discussed.

Combinatorial Particle Patterning

“…Similar to electrophotography, in magnetography, magnetic forces replace the electrostatic forces . Soft magnetic particles made of magnetic pigments dispersed in a polymer matrix have been developed in the scope of magnetography .…”
