Abstract
The present invention provides a quenching overcoat useful for application onto a lithographic printing plate, the overcoat having incorporated therein a water or fountain soluble or dispersible crystalline compound. The overcoat may be used as an oxygen barrier and/or to provide a non-tacky surface on the printing plate. By the incorporation of the crystalline compound, on-press removability of the overcoat is facilitated.
