    Abstract: Described herein is a process for preparing a flexible packaging material comprising contacting a first flexible material of a layered substrate with an intermediate transfer member; wherein the layered substrate comprises the first flexible material and a thermally activatable laminating material disposed on the first flexible material; transferring an electrophotographic ink composition from a photoimaging plate onto the thermally activatable laminating material of the layered substrate on the intermediate transfer member to form an image layer on the thermally activatable laminating material; and contacting, under conditions of heat and/or pressure, the image layer with a second flexible material thereby forming the flexible packaging material. Also described herein is an electrophotographic printer for use in the process for preparing a flexible packaging material.

    Abstract: A liquid electrophotographic (LEP) ink composition is described. The composition comprises: a pigment particle having an acidic surface modification; a basic charge director selected from:(i) a polymeric amine dispersant having a Total Base Number of at least 100 mg KOH/gram material, and (ii) a sulfosuccinate salt of the general formula MAn, wherein M is a metal, n is the valence of M, and A is an ion of the general formula (I): [R1—O—C(O)CH2CH(SO3)C(O)—O—R2]− (I); and a liquid carrier. The ink composition does not include a thermoplastic resin. Also described are a method of producing the ink composition, and a method of printing using the ink composition.

    Abstract: A system for automatic cleaning in a liquid ink printing system includes an ink tank, a pump which is configured pump a carrier liquid from the ink tank as a pressurized carrier liquid flow. A filter is configured to remove particulates from the pressurized carrier liquid flow to produce a filtered carrier liquid flow. A sprayer is configured to receive the filtered carrier liquid flow and spray the filtered carrier liquid flow into an interior of the ink tank. The pump recirculates the filtered carrier liquid flow through the filter and the sprayer. A method for automatic cleaning in a printing system is also included.

    Abstract: Systems, apparatuses, and methods of fluid delivery for liquid electrophotography printing. A fluid delivery apparatus includes a charged ink source, a supplemental fluid source, a working suspension tank in fluid communication with the charged ink source and the supplemental fluid source, a sensor, and an optical density control unit. The charged ink source is to store a charged ink mixture including charge directors and toner particles. The supplemental fluid source is to store a supplemental fluid including imaging oil. The working suspension tank is to store a working suspension mixture including the charge directors, the toner particles, and the imaging oil. The sensor is to monitor an optical density of print output of the liquid electrophotography printing apparatus. The optical density control unit is to determine whether to supply an uncharged ink mixture to the working suspension tank in response to the monitored optical density indicating electrical fatigue.
