    Abstract: An inkjet recording device includes an intermediate transfer belt, a discharger, a driving belt, a supporting member, and an adhesion unit. The intermediate transfer belt is endless and supports an intermediate image. The discharger forms the intermediate image by discharging ink onto an outer face of the intermediate transfer belt. The driving belt is endless and arranged on an inner side of the intermediate transfer belt and drives the intermediate transfer belt to run. The supporting member is arranged on an inner side of the driving belt to support the intermediate transfer belt and has a plane which is parallel to the discharger and which contacts an inner face of the driving belt facing the outer face of the driving belt and covering the area of ejection by the discharger. The adhesion unit causes the intermediate transfer belt and the driving belt to adhere to one another.

  • Publication number: 20190232674
    Abstract: Inkjet recording is performed by using an inkjet recording apparatus including an ink circulation channel for circulating a first ink, an ink supply channel for supplying a second ink into the ink circulation channel, and a recording head communicating with the ink circulation channel. The apparatus is configured to eject an aqueous ink including the first ink and the second ink from the recording head, thereby recording an image on a recording medium. The content (% by mass) of water in the first ink and the content (% by mass) of water in the second ink differ from each other by 2.00% by mass or more. The first ink contains a pigment, and the second ink contains a first water-soluble organic solvent having a log P value of ?1.10 or more and a surfactant.

    Abstract: A non-transitory storage medium stores instructions readable by an information processing apparatus. The instructions cause the information processing apparatus to: obtain a type of a printer; obtain a combination between a type of a printing medium and a color of a coloring agent for printing of a code; determine whether the obtained combination is included in a first combination or whether the obtained combination is included in a second combination; and output an alert message when the obtained combination is included in the second combination or not included in the first combination. A combination between the color and the type of the printing medium printable by the printer of the obtained type includes the first combination in which a probability of reading of the code is a first value and the second combination in which the probability is a second value less than the first value.

    Abstract: To perform high-quality printing more appropriately, a printing apparatus (10) configured to print on a medium (50) by inkjet includes: an inkjet head (102); and a UV light source (104) as an energy ray emitting unit. The UV light source (104) emits the ultraviolet rays to the ink adhered to the medium (50), causing the ink to generate heat to evaporate at least a part of a solvent in the ink. The ink ejected by the inkjet head (102) includes a polymerizing substance that polymerizes when irradiated with the energy rays, and the solvent. The ink on the medium (50) is in a state in which planarization of the ink progresses with a lapse of time at a time point after 100 ms has elapsed since the UV light source (104) emitted the ultraviolet rays.
