Abstract
Described herein is a method for priming a print substrate for subsequently receiving a liquid electrophotographic (LEP) inkin which a surface of a print substrate is coated with a first primer using an analogue printing technique and a second primer is digitally printed to the surface of the print substrate coated with the first primer.
Claims16
A method for priming a print substrate for subsequently receiving a liquid electrophotographic (LEP) ink, the method comprising:
- coating a surface of a print substrate with a first primer using an analogue printing technique, wherein the first primer includes a first primer resin dissolved or dispersed in a polar carrier liquid;
- and
- digitally printing a second primer to the surface of the print substrate coated with the first primer such that the second primer is disposed on the first primer, wherein the second primer includes a non-polar carrier liquid.
A printing apparatus comprising:
- an analogue printing station for coating a surface of a print substrate with a first primer, wherein the first primer includes a first primer resin dissolved or dispersed in a polar carrier liquid;
- and
- a liquid electrophotographic (LEP) printing station for liquid electrophotographically printing a second primer to the surface of the print substrate coated with the first primer, wherein the second primer includes a non-polar carrier liquid,
- wherein the LEP printing station comprises:
- a reservoir containing the second primer;
- and
- a photoconductive member having a surface on which a latent electrostatic image can be created, and
- wherein the printing apparatus is configured to print the second primer to the surface of the print substrate coated with the first primer such that the second primer is disposed on the first primer on the print substrate.

A printing method comprising:
- priming a print substrate to receive a LEP ink image;
- and
- liquid electrophotographically printing a pigmented liquid electrophotographic (LEP) ink image on to the primed print substrate,
- wherein priming comprises:
- coating a surface of the print substrate with a first primer using an analogue printing technique, wherein the first primer includes a first primer resin dissolved or dispersed in a polar carrier liquid;
- drying the print substrate coated with the first primer;
- and
- digitally printing a second primer to the surface of the print substrate coated with the first primer such that the second primer is disposed on the dried first primer to provide a primed print substrate, wherein the second primer includes a non-polar carrier liquid, and
- wherein the pigmented LEP ink image is printed to be disposed on the second primer on the print substrate.
