Kind Code:

B2

Abstract:

To provide a manufacturing method of printed matters, which can obtain a printed matter and a laminated body that are excellent in leveling, concentration, color development and the like and can be continuously obtained with excellent printability, and furthermore, develops excellent physical characteristics, without deteriorating a printing speed, by using an aqueous gravure ink.SOLUTION: A manufacturing method of printed matters is a manufacturing method of printed matters using an aqueous gravure ink containing a pigment and a binder resin on a first substrate, in which the ink satisfies the following (1) to (3) during printing. (1) When an aqueous gravure ink contains 50 mass% or larger of the organic pigment in all pigments, a total pigment concentration in the ink total amount is 11 to 40 mass%, and a ratio between the total pigment and the binder resin (total pigment/binder resin) is 1 to 5. (3) In the (1), the viscosity at 25°C of the ink is 10 to 70 mPa s.SELECTED DRAWING: None
