Abstract: The objective is to provide a direct drawing-type waterless lithographic printing original plate which is highly sensitive and is not susceptible to formation of blisters, namely a direct drawing-type waterless lithographic printing original plate which has a wide latitude. Provided is a direct drawing-type waterless lithographic printing original plate which has at least a heat-sensitive layer and a silicone rubber layer on a substrate in this order. The direct drawing-type waterless lithographic printing original plate is characterized in that the heat-sensitive layer contains non-photosensitive particles and the average particle diameter of the non-photosensitive particles is not less than 1/2 of the average film thickness of a portion of the heat-sensitive layer where the non-photosensitive particles are not present.

Abstract: An object of the present invention is to provide a waterless lithographic printing plate precursor that sufficiently repels ink, which tends to adhere to non-imaging areas, and maintains its repelling effects, and a printing method using a waterless lithographic printing plate obtained from the waterless lithographic printing plate precursor. The following are provided: a lithographic printing plate precursor having at least a heat sensitive layer and an ink repellent layer, wherein the ink repellent layer contains an ink repelling, the ink repellent liquid having a boiling point of not less than 150°C at 1 atmospheric pressure; and a method of producing a printed material, comprising the step of transferring an ink containing a photosensitive component in an amount from 10% by mass to 50% by mass to a printing substrate using a lithographic printing plate and then irradiating the printing substrate with ultraviolet light, wherein the lithographic printing plate precursor has at least an ink repellent layer on a substrate, an ink repellent liquid contained in the ink repellent layer has a surface tension of 30 mN/m or less.
