New High Speed Digital Press Platform using Electrocoagulation Printing

This paper will describe a new digital printing based on the Electrocoagulation of an electrolytically sensitized polymeric water-based pigmented ink. This unique system is printing variable thickness dots directly from digital input supplied in real-time by electronic memories. This computer-to-ink platform is composed of multiple shaft-less printing groups and prints 25,000 four-colour double-sided magazine pages per hour. Operational parameters of the platform will be described as well as the fundamental differences with conventional printing processes. Suitable paper properties for electrocoagulation printing will also be explored.
