An inkjet printing apparatus 1 includes an ink-jet head 23 that ejects UV curable ink to a medium M, an irradiation lamp 25 that irradiates the UV curable ink ejected to the medium M with ultraviolet rays, and a heater 37 that heats the UV curable ink after the ultraviolet ray irradiation by the irradiation lamp 25 and thereby stabilizes color fixation of the UV curable ink. The UV curable ink after the ultraviolet ray irradiation is heated at least at 35° C.

A fixer includes a fixing roller around which a recording medium is directed such that the print image to be fixed faces toward the shell surface of the fixing roller. A fixing gap is generated with a gaseous fixing medium between the shell surface of the fixing roller and the recording medium. This advantageously produces an efficient and gentle fixing of the print image.

A heating device includes a heating unit that heats in a non-contact manner an upper surface of a transport material that is transported; and a blowing unit that blows air against a lower surface of the transport material via multiple blowing holes that open with respect to the lower surface, the multiple blowing holes being disposed so that blowing holes that are closest and adjacent to each other in a transport direction of the transport material are shifted from each other in an intersection direction that intersects the transport direction.

The wind velocity of the air injected by the air-blow dryers 7a, 7b is lower than that of the air injected by the air-blow dryers 7c, 7d. That is, since a large amount of moisture remains on the front surface M1 of the printing medium M passing through the air-blow dryers 7a, 7b, the printing medium M is dried while the flow of the aqueous inks is suppressed by injecting the air at a lower wind velocity. On the other hand, the moisture decreases on the front surface M1 of the printing medium M dried by the air-blow dryers 7a, 7b and the fluidity of the aqueous inks is reduced. Accordingly, the drying of the printing medium M is promoted by injecting the air at a high wind velocity to the printing medium M passing through the air-blow dryers 7c, 7d.

In one example, an aerosol control system for a printer includes an air knife to discharge a sheet of air into a flow of aerosol along a moving print substrate web and a vacuum near the air knife to suck up aerosol from the flow simultaneously with the air knife discharging air into the flow.

System for providing marked containers comprising a computerised control system storing at least one unique identifier for each container, to be applied to a respective container, a printing unit comprising an ink delivery station, operatively connected with said computerised control system, able to print said identifier on each container, comprising a printing head filled with ink and having a plurality of nozzles configured for spraying said ink on an external surface of each container, displacement means able to perform a relative rotation, translation or rotary translation between each container and the printing head during the printing of the identifier on the container, said displacement means being operatively connected with said computerised control system.

A recording method includes: a white ink attachment step of ejecting a white ink composition containing a white coloring material from a white ink jet head and attaching the white ink composition to a recording medium; a non-white ink attachment step of ejecting a non-white ink composition containing a non-white coloring material from a non-white ink jet head and attaching the non-white ink composition to the recording medium; and a primary drying step of heating the white ink composition and the non-white ink composition attached to the recording medium by a drying mechanism. In the white ink attachment step and the non-white ink attachment step, a layer containing the white ink composition and the non-white ink composition is formed by performing main scanning multiple times, in which the ink compositions are ejected and attached to the recording medium, and by attaching the white ink composition and the non-white ink composition to the same scanning region in the recording medium by the same main scanning, while moving a position of an ink jet head relative to the recording medium.

A heating device includes a conveyor configured to convey a sheet, the sheet having a first surface on which a liquid is applied and a second surface contacting the conveyor, a first heater facing the first surface opposite to the second surface of the sheet, the first heater configured to heat the sheet, and a second heater configured to heat the conveyor.

Examples relate to a drying cylinder for an image forming apparatus. The drying cylinder comprises a curved wall and a plurality of gas outlets spaced apart over the curved wall. The drying cylinder is to continuously rotate about its longitudinal axis and provide gas through the plurality of gas outlets perpendicularly onto a print medium with printing fluid deposited thereon to dry the printing fluid.

Disclosed is a printing apparatus in which web paper is transported to a printing face contact roller in a swirling form while a direction thereof is turned by first to fourth turning rollers. Heating units are arranged so as to face a printing face of the web paper between the two first and second turning rollers, between the two third and fourth turning rollers, and between the fourth turning roller and the printing face contact roller individually. Such arrangement can achieve a compact drying mechanism. The heating units each directly heat inks on the printing face, and thus do not overheat the web paper. Moreover, the heating units are not directed upward. This avoids contact of the web paper to a front side face of each of the heating units when the web paper slackens.
