A method for producing a printed material includes forming 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; providing pressure-induced phase transition particles to a region of the recording medium, the region including the peripheral edge portion; bonding the color image and the pressure-induced phase transition particles onto the recording medium; and folding the recording medium having the color image and the pressure-induced phase transition particles bonded thereon and pressure-bonding the folded recording medium, or pressure-bonding 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. 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 ratio 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. 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.

Improved pliable print rollers for high speed drink can printing machines increase the pliable roller life five- to ten-fold at comparable ink thickness and machine speed. The improved performance results from the selection of materials utilized including a combination of elastomers, and in some case an essentially oil-free composition, and an associated manufacturing process not previously utilized to create pliable print rollers for high speed drink can printing machines. In particular a particular embodiment, the composition includes a combination of elastomers (e.g., 75% polyisoprene and 25% polybutadiene), a filler (e.g., silica), a curing agent (e.g., peroxided), and other additives (e.g., pigment, antioxidant, antiozonant) with little or no oil added as a softener. An illustrative composition including 150 parts by weight contains 100 parts elastomer, 35 parts filler, 4 parts curing agent, and 11 parts other additives (i.e., zero parts oil softener).

A printer with a laminating function, which is applied with a laminating plastic film, includes: a printer body having a printing passageway, a paper feeding port communicating with the printing passageway, and a paper feeding tray and a paper feeding wheel set; the laminating plastic film is conveyed to the printing passageway by passing the paper feeding tray and the paper feeding port; a pressurizing and heating module disposed in the printing passageway to heat and laminate the laminating plastic film; a plastic film sensor generating a plastic film signal when sensing the laminating plastic film; a process unit electrically connected to the pressurizing and heating module and the plastic film sensor; the process unit controls a heating temperature and a laminating pressure of the pressurizing and heating module after receiving the plastic film signal.

An image forming apparatus includes a first heater, a second heater, and processing circuitry. The first heater is used in an image forming process. The second heater is used in a processing process after the image forming process. The processing circuitry is to measure a temperature of the first heater, measure a temperature of the second heater, and control start of the image forming process based on a first measured temperature of the first heater and a second measured temperature of the second heater.

A sheet processing device includes a sheet storage and a sheet displacer. The sheet storage includes a first storage portion that includes a first wall that is one side wall of the sheet storage and a second wall that is part of another side wall of the sheet storage and a second storage portion that includes a third wall continuous to the first wall and the second wall. The sheet displacer displaces a preceding sheet stored in the sheet storage and contacts an upper end of the preceding sheet to displace the preceding sheet such that the upper end of the preceding sheet moves toward the third wall. The second wall and the third wall are coupled via a bent portion that bends in a manner such that a storage space of the second storage portion is greater than a storage space of the first storage portion.

A sheet laminator includes a fuser pressure member, a heater, a drive device, and circuitry. The fuser pressure member thermally fixes a two-ply sheet and a sheet medium inserted between two sheets of the two-ply sheet. The heater heats the fuser pressure member. The driver rotates the fuser pressure member. In response to a pause of a rotation of the fuser pressure member, the circuitry turns off a power supply to the heater, and perform one of immediately stopping the fuser pressure member or rotating the fuser pressure member and stopping the fuser pressure member after the rotation of the fuser pressure member, based on a state of the fuser pressure member.

A printer with a laminating function, which is applied with a laminating plastic film, includes: a printer body having a printing passageway, a paper feeding port communicating with the printing passageway, and a paper feeding tray and a paper feeding wheel set; the laminating plastic film is conveyed to the printing passageway by passing the paper feeding tray and the paper feeding port; a pressurizing and heating module disposed in the printing passageway to heat and laminate the laminating plastic film; a plastic film sensor generating a plastic film signal when sensing the laminating plastic film; a process unit electrically connected to the pressurizing and heating module and the plastic film sensor; the process unit controls a heating temperature and a laminating pressure of the pressurizing and heating module after receiving the plastic film signal.
