In some examples, a printing liquid developer includes a developer roller that has a hollow tubular base body formed of a material comprising conductive carbon fiber, a conductive, compliant layer around an outer surface of the hollow tubular base body, and an electrically conductive support separate from the hollow tubular base body and electrically contacted to a surface of the hollow tubular base body.

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.

Herein is described an electrophotographic printing process in which a liquid electrophotographic ink image and a dry electrophotographic toner image may be printed on a print substrate.

In an example, a method of wetting a print blanket includes receiving a null cycle trigger during a printing session. The method also includes maintaining printing voltages on a forecast BID (binary ink developer) that has been prepared to print a next color separation onto a photoreceptor, and applying wet null voltages to a non-forecast BID. The method then includes engaging the non-forecast BID with the photoreceptor to transfer fluid other than ink to the photoreceptor during the null cycle.

An imaging member includes a surface layer comprising a fluorosilicone and an infrared-absorbing filler. At least 75% of the siloxane units in the fluorosilicone are fluorinated. Methods of manufacturing the imaging member and processes for variably lithographic printing using the imaging member are also disclosed.
