A dry toner for direct electrostatic printing (DEP)

TL;DR: In this article, a method for direct electrostatic printing (DEP) on an intermediate substrate or on a final substrate is provided, using a device that comprises a back electrode (105), a printhead structure (106) comprising a control electrode in combination with apertures (107), and a toner delivery means (101) presenting a cloud (104) of dry toner particles in the vicinity of said aperture (107).
Patent

A DEP(Direct Electrostatic Printing)device with special printhead

TL;DR: In this article, a device for direct electrostatic printing (DEP) on an intermediate substrate or on a final substrate, comprising a back electrode (105), a printhead structure (106) made from an insulating material comprising a control electrode in combination with printing apertures (107), was provided.
Patent

An image pre-processor in a device for direct electrostatic printing

TL;DR: In this paper, an image pre-processor is described for a DEP device, wherein the image preprocessor corrects digital image data before printing, which is referred to as a shading correction in a direction orthogonal to the print direction.
Patent

A device for direct electrostatic printing (DEP) comprising a printhead structure with a current flow of at most 50 microA between shield electrode and control electrode

TL;DR: In this article, a DEP device is provided that comprises a back electrode (105), a printhead structure (106) comprising individual control electrodes (106a) in combination with printing apertures (107) and a shield electrode (106b), both electrodes separated by an insulating material and a toner delivery means.
