摘要： A printing device has a support and heating unit, a head for discharging color image ink and background image ink on a medium supported by the support and heating unit, and a controller. The controller is configured to perform one of a color image printing process for discharging the color image ink and printing a color image on the medium, and a background image printing process for discharging the background image ink and printing a background image that is a background of the color image on the medium, and to perform the other one of the processes subsequent to the one of the process. The controller is further configured to execute a wait process of evacuating the head to an evacuation position from above the support and heating unit to have the head wait at the evacuation position between the color image printing process and the background image printing process.

摘要： A recording device includes, when a transporting direction of a medium is set to a first axis and a direction intersecting with the transporting direction is set to a second axis, a head which includes a nozzle column along the first axis; a pair of heads in which the heads discharging droplets of the same color are paired; and a head unit which includes a plurality of pairs of heads along the second axis. The pair of heads include a predetermined overlapping portion in which the nozzle columns are overlapped with each other in a side view from the second axis, the overlapping portion includes a plurality of nozzle regions divided along the second axis, and a position of the nozzle region which is used in discharge of the droplets is different from a position of the nozzle region of another pair of heads.

摘要： There is provided a recording apparatus in which it is possible to use a suitable reaction liquid to be applied on the recording medium, out of multiple types of reaction liquids. A recording apparatus includes a transport mechanism that transports a recording medium, a reaction liquid applying mechanism that selectively applies, on the recording medium, either a first reaction liquid that reacts with ink or a second reaction liquid that reacts with the ink and is different from the first reaction liquid, and an ink discharge mechanism that is positioned downstream from the reaction liquid applying mechanism in the transport direction of the recording medium and discharges the ink onto the recording medium. It is preferable that the reaction liquid applying mechanism include a first reaction liquid discharge unit that discharges the first reaction liquid and a second reaction liquid discharge unit that discharges the second reaction liquid.

摘要： A printing apparatus includes a transporting section that transports a work, a printing mechanism section that has a nozzle plate that performs printing by discharging ink on the work, and a moving section that reciprocally and relatively moves the printing mechanism section in a direction intersecting the transporting direction of the work. In the printing apparatus, when the printing mechanism section moves reciprocally, printing in a forward path includes a first printing area, a second printing areas, and printing in a backward path includes a first printing area, and second printing areas. In addition, the transportation amount of the work is adjusted based on the second printing areas.

摘要： A printing apparatus is provided with a transport mechanism section that transports work, a printing mechanism section that has multiple nozzle groups, which perform printing by discharging an ink onto the work as liquid droplets, and control section that controls the actions of the transport mechanism section and the printing mechanism section. In addition, the printing mechanism section includes a first nozzle row that forms a first printing region, a second nozzle row that forms a second printing region, and an overlapping section in which the first nozzle row and the second nozzle row overlap. Further, the control section prohibits overlapping of the first printing region with the second printing region on the work when forming the third printing region.
