Abstract
An object of the present invention is to provide a method for producing printed material on which active energy ray-curable ink is printed, the method being capable of improving print density without impairing gradation expressivity. The present invention is a method for producing printed material, the method including, in order: a transfer process of transferring ink to a transfer target surface of a substrate; and an impression process of bringing each of impression cylinders into contact with the transfer target surface to which the ink has been transferred, and at least one of the impression cylinders has a patterned impression part.
Claims15
A method for producing a printed material, the method comprising, in order:
- a transfer process of:
- supplying ink to a plate cylinder with a printing plate;
- transferring the ink to a blanket cylinder upon the blanket cylinder making contact with the plate cylinder;
- transferring the ink from the blanket cylinder to a transfer target surface of a substrate to produce an image with the ink, wherein the image has a solid portion and a halftone-dot portion;
- and
- an impression process of bringing each of at least one impression cylinder having a member of an impression part into contact with the transfer target surface to which the ink is transferred from the blanket cylinder, wherein at least one member of the impression part has a patterned impression part that makes contact with the transfer target surface;
- and
- wherein upon contacting with the transfer target surface of the substrate, the patterned impression part smooths the solid portion but does not smooth the halftone-dot portion.
