Method for producing printed material and system for producing printed material

A system for producing a printed material, the system comprising:

• a pressure-induced phase transition particle providing unit that contains pressure-induced phase transition particles and provides the pressure-induced phase transition particles to one part of an outside margin portion or a portion to be folded of a recording medium;
• a bonding unit that bonds the pressure-induced phase transition particles to the recording medium;
• and
• a pressure bonding unit that pressure-bonds a multilayer body in which a plurality of recording media are stacked, the recording media including the recording medium having the pressure-induced phase transition particles bonded thereon,
• wherein the pressure-induced phase transition particles contain a styrene resin containing styrene and a vinyl monomer other than styrene as polymerization components, and a (meth)acrylic acid ester resin that contains at least two (meth)acrylic acid esters as polymerization components, and a mass ratio of the (meth)acrylic acid esters relative to a total of polymerization components of the (meth)acrylic acid ester resin is 90 mass or more, and
• the pressure-induced phase transition particles have at least two glass transition temperatures, and the difference between the lowest glass transition temperature and the highest glass transition temperature among the glass transition temperatures exhibited by the pressure-induced phase transition particles is 30° C. or more.
