A substrate preparation chamber is described herein. The substrate preparation chamber comprises an enclosure, a rotatable substrate support disposed within the enclosure, and an atmosphere replacement system coupled to the enclosure. The substrate preparation chamber can be used with an inkjet printing system, where the substrate preparation chamber is coupled to a printing enclosure such that a door is operable to place the enclosure of the substrate preparation chamber in fluid communication with the printing enclosure.

An ink jet recording method includes a treatment liquid attachment step, in which a treatment liquid is attached to a recording medium, and an ink attachment step, in which a water-based ink composition is attached to the recording medium. An ink jet recording apparatus includes a recording medium support and a heating mechanism that heats the recording medium support. The ink attachment step is carried out with the recording medium supported and heated by the recording medium support. In the ink attachment step, the recording medium is heated so that a surface thereof reaches a maximum temperature of 28.0° C. or more and 45.0° C. or less. The ratio between absorbances A and B (A/B) is 0.5 or more and 0.95 or less, where absorbance A is that of a 0.1% by mass mixture of the water-based ink composition in the treatment liquid, and absorbance B is that of a 0.1% by mass mixture of the water-based ink composition in purified water. The recording medium support has a flat support surface for supporting the recording medium.

An inkjet recording method contains the sequential steps of: applying an aqueous pre-coat composition to a substrate, or applying and drying the aqueous pre-coat composition to the substrate; and subsequently applying and drying an aqueous ink composition. The aqueous pre-coat composition contains at least an aggregating agent. The aqueous ink composition contains at least a pigment, a polymer dispersant, and resin fine particles. The aggregating agent is selected from a pyrolytic cation resin, an organic acid, or a multivalent metal salt. A neutralizer for the polymer dispersant is selected from an organic amine. In the step of drying the aqueous ink composition, a temperature at which the aqueous ink composition is dried is set to be equal to or higher than a pyrolytic temperature of the aggregating agent.

A staged printing system includes: a printing station for printing an image upon an object; a curing station, operatively connected to the printing station, for curing the image printed upon the object; and a pretreatment station, operatively connected to the printing station, for pretreating the object before printing an image upon the object. The printing station includes a plurality of vertically mounted print heads for ejecting ink and a rotating platform for rotating the object as the plurality of vertically mounted print heads eject ink upon the object.

Provided is an ink including water, and an organic solvent, wherein a dried product of the ink has an endothermic peak temperature Tm of 22° C. or higher but 74° C. or lower as measured by differential scanning calorimetry, the differential scanning calorimetry includes first heating, cooling, and second heating, where the first heating is heating the dried product of the ink from −60° C. to 140° C. at a heating rate of 10° C./min, the cooling, which is performed after the first heating, is cooling a heated product obtained in the first heating from 140° C. to −60° C. at a cooling rate of −10° C./min, and the second heating, which is performed after the cooling, is heating a cooled product obtained in the cooling from −60° C. to 140° C. at a heating rate of 10° C./min, and the endothermic peak temperature Tm is an endothermic peak temperature in the second heating.

A heating device heats a sheet to which a liquid discharge unit discharges a liquid. The heating device includes a first heater to heat the sheet that has passed through the liquid discharge unit, a vacuum conveyor to convey the sheet that has passed through the first heater while sucking the sheet, a second heater to heat the sheet being conveyed by the vacuum conveyor, and circuitry that cause the first heater to heat the sheet when sheet data regarding the sheet satisfies a predetermined condition.

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.

An inkjet printing apparatus for printing on a printing medium by dispensing inks thereto. The apparatus includes a transport device; print heads for performing printing by dispensing the inks to the printing medium; and a drying section including a heat source for generating heat for drying the inks dispensed to the printing medium, and a shutter switchable between an open state and a closed state. In the open state, a drying amount of heat is applied for drying the inks dispensed to the printing medium, and in the closed state, the heat from the heat source is applied in a minute amount of heat smaller than the drying amount of heat. A controller switches the shutter to the open state when a transporting speed of the printing medium is faster than a predetermined threshold, and switches the shutter to the closed state when the transporting speed of the printing medium becomes equal to or less than the predetermined threshold.

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.

The ratios (Wp1/Wm1, Wp2/Wm2) of the pattern widths Wp1, Wp2 to the paper widths Wm1, Wm2 are obtained, respectively, after the first drying and after the second drying (Step S109). Then, in accordance with these ratios, a range (in other words, the width) in which the back print image G2 is to be printed is adjusted in the width direction Aw (Step S204). As a result, when the double-sided printing is performed on the continuous form paper M by performing drying every time when the image is printed on each of the surfaces Ma, Mb of the continuous form paper M, it is possible to suppress the difference in the ratios of the widths of the images G1, G2 to the width of the continuous form paper M between the surfaces Ma and Mb of the continuous form paper M.
