비화선부에 부착되기 쉬운 잉크에서도 충분하게 반발시키고, 그 반발 효과가 지속되는 잉크 반발층을 갖는 무습수 평판 인쇄판 원판, 및 상기 무습수 평판 인쇄판 원판을 사용한 인쇄 방법을 제공한다. 적어도 감열층과 잉크 반발층을 갖는 평판 인쇄판 원판으로서, 상기 잉크 반발층 중에 잉크 반발성의 액체를 함유하고, 상기 액체의 1기압에 있어서의 비점이 150℃ 이상인 평판 인쇄판 원판이다. 또한, 평판 인쇄판을 이용하여 피인쇄체에 감광성 성분을 10질량% 이상 50질량% 이하 포함하는 잉크를 전사한 후, 상기 피인쇄체에 자외선을 조사하는 공정을 포함하는 인쇄물의 제조 방법으로서, 상기 평판 인쇄판의 인쇄판 원판이 기판 상에 적어도 잉크 반발층을 갖고, 상기 잉크 반발층 중에 포함되는 잉크 반발성의 액체의 표면장력이 30mN/m 이하인 인쇄물의 제조 방법이다. 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.
