Phase separation ink

A process which comprises:

• (1) incorporating into an ink jet printing apparatus a phase change ink comprising at least one crystallizable component comprising a material that crystallizes as it cools from a first ink jetting temperature to a second temperature that is lower than the ink jetting temperature, wherein the second temperature is sufficient to initiate crystallization of the at least one crystallizable component;
• at least one amorphous component comprising a material that remains amorphous at the second temperature;
• and an optional colorant;
• wherein the at least one crystallizable component and the at least one amorphous component are in a molten, single phase state at the first ink jetting temperature;
• wherein at the second temperature, the phase separation ink comprises a crystalline phase comprising the at least one crystallizable component and an amorphous phase comprising the at least one amorphous component;
• wherein the at least one crystallizable component is diphenethyl L-tartrate and the at least one amorphous component is di-L methyl L-tartrate;
• or
• wherein the at least one crystallizable component is Bis(4-methoxyphenyl) octanedioate and the at least one amorphous component is tri-DL-menthyl citrate;
• (2) melting the ink;
• (3) causing droplets of the melted ink to be ejected in an imagewise pattern onto an intermediate transfer member or directly onto the final image receiving substrate;
• and
• (4) optionally, if an intermediate transfer member is used, transferring the image to the final image receiving substrate.
