Abstract
To provide a manufacturing method of a printed matter capable of stably obtaining a high-quality printed matter for a long period of time, with excellent curing properties even with two or less active energy ray sources, when printing two or more kinds of active energy ray-curable compositions.SOLUTION: A manufacturing method of a printed matter includes: a printing step of printing two or more kinds of active energy ray-curable compositions onto a substrate P; and a curing step of emitting an active energy ray from an irradiation device to cure the active energy ray-curable compositions on the substrate P. The two or more kinds of active energy ray-curable compositions include a (meth)acrylate compound. The irradiation device 7 is equipped with n pieces (n is an integer of 2 or larger) of active energy ray sources. If the two or more kinds of active energy ray-curable compositions include one with an iodine value IV of lower than 100, n pieces of active energy ray sources are lit and the active energy ray LB is emitted. If every iodine value IV is 100 or higher, (n-1) pieces or less active energy ray sources are lit and the active energy ray LB is emitted.SELECTED DRAWING: Figure 6A
