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.

Method for producing printed matter and printing machine

The present invention pertains to a fluorescent-material-containing resin sheet to be used as a light-emitting element. The present invention addresses the problem of obtaining a fluorescent-material-containing resin sheet which exhibits excellent formability, favorable light resistance, and favorable heat resistance, and when used as a light-emitting element, has high brightness and low variation in light emission between chips. As a means of solving this problem, this fluorescent-material-containing resin sheet contains a fluorescent material, a resin, and metal oxide particles (I) having an average particle diameter of 10-200 nm, wherein the amount of the fluorescent material contained therein is 250-1000 parts by mass per 100 parts by mass of the resin. Preferably, this sheet also contains metal oxide particles (II) having an average particle diameter of 300-1000 nm, and as a separate embodiment, preferably contains silicone fine particles.
