Zusammenfassung:	To provide, in lithographic printing using non-processed CTP plate 10, a dampening water concentrated composition for lithographic printing plate that can suppress the occurrence of stains on non-image area 12 of a printed matter during printing.SOLUTION: The dampening water concentrated composition for lithographic printing plate contains, as essential component, a polyoxyethylene polyoxybutylene block polymer, a polyoxyethylene sorbitan monofatty acid ester, a dialkylsulfosuccinate, and an alkylene glycol monoalkyl ether. The dampening water concentrated composition for lithographic printing plate is diluted with tap water and used as dampening water 1.SELECTED DRAWING: Figure 1 【課題】無処理ＣＴＰ版１０を用いた平版印刷において、印刷中に印刷物の非画像部１２に汚れが発生することを抑制することができる平版印刷版用湿し水濃縮組成物を提供すること。【解決手段】平版印刷版用湿し水濃縮組成物は、必須成分として、ポリオキシエチレンポリオキシブチレンブロックポリマー、ポリオキシエチレンソルビタンモノ脂肪酸エステル、ジアルキルスルホ琥珀酸塩、アルキレングリコールモノアルキルエーテル、を含有する。平版印刷版用湿し水濃縮組成物は、上水で希釈され、湿し水１として使用される。【選択図】図１
