The object is to suitably satisfy a condition for preventing smearing of a printed object and a condition for endowing glossiness to the printed object. As a solution therefor, a plurality of inkjet heads (12y, 12m, 12c, 12k), a print heater (104) being a medium heating heater, and a sub-scan driving unit (16) being an opposing position changing unit that sequentially causes each of positions in a medium (50) in a moving direction of the medium (50) to oppose the respective inkjet heads (12y, 12m, 12c, 12k) are provided, where ink is ink containing solvent and is fixed onto the medium (50) by the solvent being dried, and the print heater (104) dries the ink that has been discharged from one of the inkjet heads and struck onto the medium before another inkjet head further discharges an ink droplet onto a struck position of the ink.

A printing apparatus can prevent a print medium from buckling during discharging. In a case in which the print conveyance speed determined by the print mode is higher than or equal to a specified speed, the print medium after printing is conveyed to a discharging tray at the print conveyance speed, and in a case in which the print conveyance speed determined by the print mode is lower than the specified speed, the print medium after printing is conveyed to the discharging tray at the specified speed increased from the print conveyance speed.

An inkjet recording apparatus includes an ink jetter that jets ink and a transfer unit that has a ring-shaped intermediate transfer body. The transfer unit transfers, to a recording medium, a primary image formed on an outer circumferential surface of the intermediate transfer body with the ink that is jetted to land on the outer circumferential surface by the ink jetter. The transfer unit includes a heater that heats air in an internal space of the intermediate transfer body enclosed by an inner circumferential surface of the intermediate transfer body, and an air mover that flows the air in the internal space.

A liquid discharge device determines, in a state of a liquid discharger discharging liquid onto a continuous form sheet conveyed by a conveyor at a first conveying speed, in response to a seam of the continuous form sheet detected by a seam detection sensor, whether a heater temperature detected by a temperature detection sensor is a threshold or higher; causes, in response to the heater temperature being determined to be the threshold or higher, the conveyor to stop conveying the continuous form sheet, until the heater temperature decreases to be less than the threshold; and causes, in response to the heater temperature having decreased to be less than the threshold, the conveyor to convey the continuous form sheet at a second conveying speed slower than the first conveying speed until the seam of the continuous form sheet is wound up around a winding roller.

A printed matter exhibiting metallic gloss is provided and includes: a substrate; and a metallic glossy layer, being formed on the substrate, and the metallic glossy layer containing scaly particles having a metal. In the metallic glossy layer, the scaly particles are oriented to be substantially parallel to a surface of the metallic glossy layer; and the surface of the metallic glossy layer has a DOI value of greater than or equal to 20% and a Sa value of less than or equal to 2 μm.

A post-printing treatment for printed media includes a wax suspended in water. Particles of the wax to lie upon at least an inkjet ink image on the printed media to facilitate abrasion resistance of the image.

A porous layer included in a transfer body for image recording by a heat transfer method has a multiple layer configuration, and porous layers are provided such that when a thickness (mm) of each porous layer from a porous layer P(1) of the plurality of porous layers on a side closest to the surface layer to a porous layer P(n) on a side closest to the substrate is set to t(n) (n≥2), and a total thickness of the transfer body is set to T (mm), Expression (1): C×T≤t(1)+ . . . +t(n) (here, C=0.4, and T≥1) is satisfied.

A medium processing apparatus includes a third support surface configured to support a medium downstream from a recording unit in a transport direction, the transport direction being a direction in which the medium to be printed by the recording unit putting a liquid on the medium is transported, a heating unit facing the third support surface and including a heating element configured to heat the medium supported by the third support surface, a first outlet opening toward the support surface, and a blower configured to blow out gas from the first outlet, wherein the first outlet is located closer to the recording unit than the heating unit is located, and is configured such that the gas blown out from the first outlet is directed along the third support surface and is directed away from the recording unit.

An ink-jet ink printing method and associated system can have a printer including an ink-jet ink. The ink includes an aqueous liquid vehicle, 1 wt % to 5 wt % pigment, 1 wt % to 5 wt % acrylic polymer particles, 0.3 wt % to 3 wt % urethane polymer particles, and is formulated to print on a vinyl medium. The system also includes a heating device. Upon applying heat to the ink-jet ink printed on the vinyl medium, the polymer particles in the printed ink fuse, and form a film encapsulating at least a portion of the pigment on the vinyl print medium.

A heating device includes a first member having a first sheet holding face, and a second member having a second sheet holding face and disposed facing the first sheet holding face of the first member. The first and second sheet holding faces are configured to hold a sheet between the first and second sheet holding faces. The sheet has a resin surface on at least one face of the sheet. The heating device is configured to heat the sheet while the first and second sheet holding faces hold the sheet on which liquid is applied. At least one of the first and second sheet holding faces is configured to contact the resin surface of the sheet. The at least one of the first and second sheet holding faces has an uneven surface with a plurality of convex or concave portions.
