    Abstract: A method of lithographic printing includes the steps of (i) providing a heat-sensitive lithographic printing plate precursor including, on a support having a hydrophilic surface or which is provided with a hydrophilic layer, a coating having a polymer modified with at least two groups which can form four hydrogen bonds, the groups being defined as quadruple hydrogen bonds (QHB groups); (ii) exposing the printing plate precursor to heat and/or infrared light whereby the coating switches from a hydrophilic state into a hydrophobic state or from a hydrophobic state into a hydrophilic state, thereby producing a lithographic printing master without an intermediate wet development step; and (iii) supplying ink and/or fountain solution to the lithographic printing master via a lithographic printing press.
