The present invention aims to provide a method of producing a printed matter that shows suppressed scumming in planography. A method of producing a printed matter, the method including the steps of: allowing a dampening water to adhere to a hydrophilic layer of a planographic printing plate having at least the hydrophilic layer and a heat sensitive layer; allowing an ink to adhere to the heat sensitive layer; and transferring the ink adhering to the heat sensitive layer to an object to be printed; wherein the pH (A) of the ink and the pH (B) of the dampening water are both from 1 to 6.5.
本发明旨在提供一种生产印刷品的方法,这种印刷品在平版印刷中显示出被抑制的浮渣现象。一种生产印刷品的方法,该方法包括以下步骤:让润湿
水附着在至少具有亲
水层和热敏层的平版印刷板的亲
水层上;让油墨附着在热敏层上;以及将附着在热敏层上的油墨转移到待印物体上;其中,油墨的 pH 值(A)和润湿
水的 pH 值(B)均为 1 至 6.5。
