  • Publication number: 20190025734
    Abstract: Herein is disclosed a method for electrostatic printing. The method may comprise: a. electrostatically printing a discontinuous layer of a transparent electrostatic ink in a first area on a print substrate; b. electrostatically printing an image comprising a coloured electrostatic ink on the print substrate in a second area, which may or may not be in the same location as the first area, wherein the electrostatic printing in each of steps a and b involves, respectively, transferring the transparent electrostatic ink or the coloured electrostatic ink from a photoimaging plate to the print substrate via an intermediate transfer member. The method may then involve repeating steps a and b on the same or different print substrates, wherein each repeat of step b results in the same or a different printed image, and the discontinuous layer of transparent electrostatic ink varies between at least two different printing patterns. A system is also disclosed herein.

  • Publication number: 20160243619
    Abstract: 3D (three-dimensional) ink jet printing includes techniques for evaporating a carrier liquid during printing while at least a portion of dispersant remains in the printed layer; evaporating dispersant in a first layer prior to sintering the first layer and/or prior to printing a second layer; leveling an upper-layer of a printed object using a horizontal roller; and printing layers of an object, each layer with both object and support portions, resulting in an object with support, in particular, support for negative angles and molds.

  • Publication number: 20150177667
    Abstract: An image forming apparatus includes a determination unit, a print unit, and an image forming blanket. The determination unit may determine a raised support image having a support perimeter to be printed on an impression media corresponding to a type of media. The print unit may at least one of print the image to be transferred by the image forming blanket to the media and print the raised support image determined by the determination unit on the impression media. The support perimeter may be smaller than the media perimeter. The image forming blanket may transfer the image to a front surface of the media from the image forming blanket by contacting the media and bending the edge portion of the media about the raised support image.

  • Patent number: 8583021
    Abstract: A method of maintaining a photoconductive member of an image forming apparatus is disclosed. The method includes applying fluid to a photoconductive member to form an image thereon, transferring the fluid from the photoconductive member in the form of the image and providing sponge applicator fluid to respective sponge applicator units. The method also includes squeezing the sponge applicator units to remove at least a portion of the sponge applicator fluid therefrom and sequentially placing each one of the sponge applicator units in contact with the photoconductive member to cool and clean the photoconductive member.
