Method of lithographic printing with a reusable substrate.

摘要

A method for treating a micro-emulsion that can be used for removing the ink-accepting areas of a lithographic printing master is disclosed, which enables to recycle the water from the used micro-emulsion. The method comprises the heating of the micro-emulsion to a temperature above 50 DEG C thereby obtaining an aqueous phase and an organic phase and separating the aqueous phase from the organic phase.
