ABSTRACT:
A printing ink emulsion system containing an oil-base phase and water-miscible phase and exhibiting a high degree of stability against phase separation in use. The composition contains a small amount of phosphoric acid as a stabilizer, and is characterized in that the printing emulsion functions effectively as a single-application-step formulation in which the ink is retained only by the image portion of a plate, thus obviating the need for a separate operational step in which water is applied to a non-image area of a printing plate or roller to render that area ink-repellant.
