1. A system for producing a printed material, the system comprising:
a color image forming unit that forms a color image having an image area ratio of 20% or less on a peripheral edge portion of a recording medium by using a coloring material;
a pressure-induced phase transition particles-providing unit that stores pressure-induced phase transition particles and provides the pressure-induced phase transition particles to a region of the recording medium, the region including the peripheral edge portion;
a bonding unit that bonds the color image and the pressure-induced phase transition particles onto the recording medium; and
a pressure-bonding unit that folds the recording medium having the color image and the pressure-induced phase transition particles bonded thereon and pressure-bonds the folded recording medium, or that pressure-bonds the recording medium having the color image and the pressure-induced phase transition particles bonded thereon and another recording medium placed on top of each other,
wherein:
the pressure-induced phase transition particles contain a styrene resin and a (meth)acrylic acid ester resin, the styrene resin contains styrene and a vinyl monomer other than styrene as polymerization components, the (meth)acrylic acid ester resin contains at least two (meth)acrylic acid esters as polymerization components, and a mass ration of the (meth)acrylic acid esters is 90 mass % or more of a total of all polymerization components of the (meth)acrylic acid ester resin, and
the pressure-induced phase transition particles have at least two glass transition temperatures, and a difference between the lowest glass transition temperature and the highest glass transition temperature among the glass transition temperatures of the pressure-induced phase transition particles is 30° C. or more.
