Zusammenfassung:	To provide a pretreatment ink that prevents white spots, reduces the defects of insuffient filling of water-based ink, and can produce recorded matter having high image reproducibility.SOLUTION: A pretreatment ink, which is pre-applied onto a base material before a water-based ink is applied onto the base material, contains at least a reaction agent, water, and an organic solvent. The organic solvent includes a water-soluble solvent A selected from the group consisting of alkanediols and monools.SELECTED DRAWING: None 【課題】白抜けを抑制し、水性インクの埋まり不良の発生を抑制し画像再現性の高い記録物を製造可能な前処理インクを提供する。【解決手段】水性インクを基材に塗布する前に予め基材の塗布する前処理インクであって、少なくとも反応剤と、水と、有機溶剤と、を含有し、有機溶剤は、アルカンジオール及びモノオールからなる群より選択される水溶性溶剤Ａを含有する前処理インクである。【選択図】なし
