Abstract: The present disclosure relates to a process for selectively printing an image onto a substrate. The process comprises electrophotographically printing a first ink composition onto selected areas of a substrate. The process also comprises applying a primer over at least the unprinted areas of the substrate. A second ink composition is printed onto the primerand the first ink compositionis removedfrom the selected areas of the substrate. The first ink composition is a transparent electrophotographic ink composition.

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.

Abstract: The present disclosure relates to a process for printing a substrate. The process comprises applying an analogue primer over a print substrate. A transparent electrophotographic composition comprising a coupling agent is electrophotographically printed on the primer as a coupling layer. An electrophotographic ink composition is then printed on the coupling layer to form an image layer. The coupling layer is disposed between the primer and image layer and in contact with each of the primer and image layer.
