Digital offset lithography ink composition

A process of digital offset printing with a digital offset printing device, the process comprising:

• applying an ink composition onto a re-imageable imaging member surface at an ink take up temperature, the re-imageable imaging member having dampening fluid disposed thereon;
• forming an ink image;
• transferring the ink image from the re-imageable surface of the imaging member to a printable substrate at an ink transfer temperature;
• wherein the ink composition comprises:
• at least one component selected from the group consisting of a curable monomer and a curable oligomer;
• an optional dispersant;
• an optional photoinitiator;
• and
• at least one non-radiation curable additive,
• wherein the non-radiation curable additive is a detergent or an emulsifying agent, or wherein the non-radiation curable additive functions as a detergent or emulsifying agent when in the presence of a cleaning fluid,
• wherein the non-radiation curable additive is a solid at a temperature of from about 20° C. to about 40° C.,
• wherein the non-radiation curable additive is behenyl behenate or polycaprolactone-block-polytetrahydrofuran-block-polycaprolactone.

A process comprising:

• combining at least one component selected from the group consisting of a curable monomer and a curable oligomer;
• an optional dispersant;
• an optional photoinitiator;
• and at least one non-radiation curable additive wherein the non-radiation curable additive is a detergent or an emulsifying agent, or wherein the non-radiation curable additive functions as a detergent or emulsifying agent when in the presence of a cleaning fluid, wherein the non-radiation curable additive is a solid at a temperature of from about 20° C. to about 40° C., and wherein the non-radiation curable additive is behenyl behenate or polycaprolactone-block-polytetrahydrofuran-block-polycaprolactone;
• optionally, heating;
• and
• optionally, filtering;
• to provide an ink composition.
