Abstract
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.
Claims9
A method for producing a printed matter by printing ink on a film, comprising using a film having a nitrogen element concentration of 0.5 to 10.0 atom % in the film surface and irradiating with an active energy ray after printing,
- wherein a surface layer of the film is a layer having a nitrogen compound including at least one of melamine compounds and urethane compounds,
- wherein the ink is an active energy ray-curable printing ink including a pigment (a), a resin having an ethylenic unsaturated group (b), and a (meth)acrylate (c),
- wherein the resin having an ethylenic unsaturated group (b) has a carboxyl group, and an acid value of the resin is 30 mgKOH/g or more and 250 mgKOH/g or less.
