Priming a polymeric print substrate

A printing system comprising:

• an analogue printing station for coating a surface of a polymeric print substrate with a first primer;
• and
• a liquid electrophotographic (LEP) printing station for liquid electrophotographically printing a second primer to the surface of a polymeric print;
• and
• a polymeric print substrate, 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 system is configured to print the second primer to the surface of the polymeric print substrate coated with the first primer such that the second primer is disposed on the first primer on the polymeric print substrate.

A printing method comprising:

• priming a polymeric print substrate to receive a LEP ink image;
• and
• liquid electrophotographically printing a pigmented liquid electrophotographic (LEP) ink image on to the primed polymeric print substrate,
• wherein priming comprises:
• coating a surface of the polymeric print substrate with a first primer using an analogue printing technique;
• and
• digitally printing a second primer to the surface of the polymeric print substrate coated with the first primer to provide a primed polymeric print substrate, and
• wherein the pigmented LEP ink image is printed to be disposed on the second primer on the polymeric print substrate.
