Abstract: 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° C. thereby obtaining an aqueous phase and an organic phase and separating the aqueous phase from the organic phase.

Abstract: A direct-to-plate method of lithographic printing is disclosed which enables to recycle the lithographic substrate of the printing master. The method comprises the steps of (a) making a negative-working imaging material by coating on a hydrophilic substrate a coating solution comprising hydrophobic thermoplastic polymer particles and a hydrophilic binder; (b) making a printing master having ink-accepting areas by image-wise exposing the imaging material; (c) applying ink and fountain solution to the printing master; (d) removing the ink-accepting areas from the printing master by supplying a aliphatic or aromatic compound having a structure comprising at least 6 carbon atoms. The above steps are preferably carried out on-press.
