  • Publication number: 20200122460
    Abstract: A method comprises: providing a first stream of discrete volumes (908b) of material, and directing a pulsed laser beam (912) at a first discrete volume (908b) of material in the first stream of discrete volumes of material so as to interact with the first discrete volume of material and thereby displace the first discrete volume away from the first stream. An apparatus and a system for achieving such steps are also disclosed.

  • Patent number: 10514635
    Abstract: Herein is described a liquid electrostatic printing method comprising providing a liquid electrostatic ink composition comprising a carrier liquid and chargeable particles comprising a resin; and providing an adhesion promoting composition comprising an adhesion promoter. The liquid electrostatic ink composition is contacted with a latent electrostatic image disposed on a surface to create a developed ink image. The developed ink image is transferred to an intermediate transfer member. The adhesion promoting composition is deposited on the intermediate transfer member to form an adhesion promoting layer. The adhesion promoting layer and the developed ink image are transferred to a print substrate, such that the adhesion promoting layer is disposed on the print substrate and the developed ink image is disposed on the adhesion promoting layer.

  • Patent number: 10306108
    Abstract: A halftone comprises a first halftone screen and a second halftone screen. The first halftone screen comprises a first plurality of amplitude modulated dots arranged according to a first plurality of rows, the first plurality of rows being orientated according to a first direction and comprising a first dot spacing. The second halftone screen comprises a second plurality of amplitude modulated dots arranged according to a second plurality of rows, the second plurality of row being orientated in a second direction and comprising a second dot spacing. The first direction and the second direction define an angle of 45 degrees or less and a ratio of the second dot spacing to the first dot spacing is less than one.
