A formulation comprising a heat sensitive cross-linkable ink and carbon black is coated over substantially the entirety of an ink-repellent/ink-releasing surface of a printing cylinder of a printing press by heating the formulation and/or the outer surface of the printing cylinder so that the formulation adheres to the cylinder to provide a continuous coating thereon. The coated printing cylinder is then allowed to cool to ambient temperature whereafter it can be imaged using a digitally controlled laser. The imaged printing cylinder may be developed during press start up by application of waterless ink over the cylinder surface in order to remove the non-imaged areas comprising non-cross-linked ink. After completion of printing, the printing cylinder can be cleaned by using an appropriate solvent to solubilise the cross-linked ink in the imaged areas and subsequently re-used.
