Ink Transfer Subsystem for a Variable Data Lithography System

Номер: US20120103219A1

Автор: Ashish Pattekar, Timothy Stowe

Принадлежит: Palo Alto Research Center Inc

An improved imaging member for a variable data lithography system comprises a reimageable surface layer comprising a polymer, the reimageable surface having a surface roughness Ra in the range of 0.10-4.0 μm peak-to-valley, and peak-to-valley nearest neighbor average distances finer than 20 μm. A structural mounting layer may be provided to which the reimageable surface layer is attached, either directly or with intermediate layers therebetween. The relatively rough surface facilitates retention of dampening solution and improves inking uniformity and transfer. The reimageable surface layer may be comprised of polydimethylsiloxane (silicone), and may optionally have particulate radiation sensitive material disbursed therein to promote absorption, and hence heating, from an optical source.

A flexographic printing system uses a flexographic printing plate to produce printed patterns on a substrate. A fountain roller partially submerged in ink in an ink pan is used to transfer ink to an anilox roller, which transfers a controlled amount of ink to the flexographic printing plate. An ink recirculation system is used to reduce variability in system performance resulting from ink viscosity changes. A recirculation pump moves ink through an ink recirculation line connected to an ink recirculation port in an ink pan. The design of the ink pan and ink recirculation port is arranged so that an opening of the ink recirculation port is fully covered by the ink during printing by the flexographic printing system.
