Provided is active energy ray-curable ink for offset printing which has marked curability and toning resistance during printing, exhibits good transferability and adhesiveness to plastic films having low wettability, and imparts high hiding power to printed matter. The active energy ray-curable ink for offset printing includes a pigment, a polyfunctional (meth)acrylate having a hydroxyl group, and a resin having an ethylenic unsaturated group and a hydrophilic group.

Provided are a method for producing a printed matter and a printing machine which suppress the decrease of transferability and improve adhesiveness between ink and a film substrate when ink is printed on the film substrate. The method for producing a printed matter of the present invention is a method for producing a printed matter by printing ink on a film, which uses a film having a nitrogen element concentration of 0.5 to 10.0 atom % in the film surface, and includes irradiating with an active energy ray after printing.

Described herein is a process for preparing a flexible printed material.
