Abstract: To provide is a manufacturing method for obtaining printed material in which, in lithographic printing, a printed part where multiple colors are superimposed on each other has a high gloss, and also a lithographic printing ink set. The method for manufacturing printed material according to the present invention includes a step of coating at least black ink for lithographic printing, cyan ink for lithographic printing, magenta ink for lithographic printing, and yellow ink for lithographic printing on a substrate, in which a difference in surface tension between the inks to be coated on a substrate is at most equal to 3.5 mN/m. The lithographic printing ink set according to the present invention is a lithographic printing ink set including at least black ink, cyan ink, magenta ink, and yellow ink, in which a difference in surface tension between the inks included in the lithographic printing ink set is at most equal to 3.5 mN/m.
