The present invention discloses a high weight percent of silicone within the silicone-urea block polymer for use with or as a dielectric layer material for electrostatic printing. The high weight percent comprises between about 66 and about 94 weight percent.

Dielectric image release surface containing a high percent silicone composition and uses therefor

A system and method of reducing striations in electrostatic printing is provided by varying plate firing sequences in a pattern of nib groups on the writing head of an electrostatic printer to visually mute the effects of sequence striations. This variation, in combination with other techniques, minimize multiplexing striations that affect adversely the print quality of data emerging from high speed, wide width electrostatic printers.

System and method for reducing striations in electrostatic printing

A system for substantially maintaining color density in liquid toners for electrographic printers is disclosed. The system includes means for substantially continuously supplying toner concentrate to a printer and means for substantially continuously withdrawing liquid toner from a printer into a waste flowstream. A method to achieve substantially consistent color density of liquid toner in an electrographic printing system is also disclosed.

A method and apparatus to reduce fogging on electrostatic printing media is disclosed. A negative bias is applied to toning station(s) or vacuum station(s) of the printing apparatus with isolation of that negative bias from the printing media.

Method and apparatus to reduce fogging in electrostatic printing

A method and apparatus to improve toner drying on electrostatic printing media is disclosed. A drying apparatus placed between two print stations in a single pass electrostatic printer provides air from two different drying assemblies, one adjacent to one print station and a second adjacent to a second print station.

Method and apparatus to dry media during electrostatic printing

A toner station for use in single-pass or multi-pass electrostatic printers includes two or more toner applicators for each color, thereby increasing the printing speed without degrading print quality.

Method and apparatus for applying liquid toner to a print medium using

The adhesion of metal to a polyimide substrate is enhanced by depositing onto at least one surface of the polyimide a thin film of metal such as copper and heating in air to cause the deposited metal to texturize that surface by producing asperities that are at least 0.05 .mu.m in average height and average breadth. In doing so, metal oxide clusters are formed at the textured surface. When the textured surface is metallized, the resulting composite resists delamination even at soldering temperatures.
