摘要： An ink-jet printer includes: a base material transport mechanism for transporting a base material along a transport path in a transport direction; an ink ejection head having a lower surface opposed to the transport path, and an ink ejection port for ejecting ink toward the transport path; and a base plate having a lower surface opposed to the transport path over the transport path, and a mounting hole open in the lower surface, the ink ejection head being mounted in the mounting hole. The base plate includes an air flow hole that is a though hole penetrating through the base plate. The air flow hole has an air outlet open in a location downstream of the ink ejection port in the lower surface. Air passing through the air flow hole is ejected from the air outlet toward the transport path.

摘要： A printing apparatus (1) includes a controller (40) for applying tension to a base material (9) to be printed thereon while applying brake torque to an unwinding roller (11) around which the base material (9) is wound, and a tension sensor (14) for detecting the tension applied to the base material (9). The controller (40) acquires information related to the base material (9). The controller (40) exercises first control for rotating the unwinding roller (11) with a constant acceleration, if the acquired information is included in a first condition. The controller (40) exercises control for rotating the unwinding roller (11) with an acceleration slower than the constant acceleration and/or with an S-shaped acceleration, if the acquired information is not included in the first condition.

摘要： In an inkjet printer where any two ink ejection parts provided upstream and downstream in a conveyance direction of a base member are referred to as first and second ink ejection parts, the first ink ejection part ejects a first ink, a droplet of which when deposited on the base member has a surface tension decreasing with time. The second ink ejection part ejects a second ink, a droplet of which when deposited on the base member has a surface tension that is substantially equal to a surface tension of the droplet of the first ink deposited on a position adjacent to the droplet of the second ink. The printer can therefore make substantially equal the surface tensions of droplets of the first and second inks, deposited on adjacent positions, thus reducing bleeding in a boundary between areas of the inks or variation in the position of the boundary.
摘要翻译：在将基材的输送方向上下游配置的两个墨喷出部分称为第一墨喷出部和第二喷墨部的喷墨打印机中，第一墨喷射部喷射第一墨，基底部件的表面张力随时间而下降。第二墨水喷射部分喷射第二墨水，当其沉积在基底部件上时，液滴的表面张力基本上等于沉积在邻近第二墨滴的位置的位置上的第一墨水的液滴的表面张力墨水。因此，打印机可以使沉积在相邻位置上的第一和第二墨水的液滴的表面张力基本相等，从而减少墨水区域之间的边界的渗色或边界位置的变化。

摘要： The technique provided enables, when first ink is precured and second ink is ejected thereon, ensuring sufficient adhesion of the second ink via a primer. A printer includes a transport mechanism, a primer ejection head (21), a second light irradiator (32), a white-ink ejection head (22), a color-ink ejection head (23), and a controller (50). The controller controls the amount of primer ejected to a unit region of a continuous base material by the primer ejection head, the amount of white ink ejected thereto by the white-ink ejection head, and the amount of color ink ejected thereto by the color-ink ejection head. The controller determines a first primer amount based on the amount of white ink and determines a second primer amount based on the amount of color ink. The controller then determines an ultimate primer amount based on the sum of the first primer amount and the second primer amount.

摘要： An inkjet printing apparatus performs printing on a printing medium by feeding ink to an inkjet head having a plurality of nozzles and dispensing the ink from the inkjet head to the printing medium. The apparatus includes a tank, a supply pipe communicatively connecting the tank and the inkjet head, a pump for feeding the ink stored in the tank to the inkjet head, a filter disposed on a path of the supply pipe, and a controller for operates the pump and controlling feeding of the ink. The controller operates the pump to engage in forward drive in time of printing operation, and operates the pump to engage in backward drive in time of functional recovery operation.

摘要： An inkjet printing apparatus 1 includes: a casing 90; a transport mechanism 10 that transports a recording medium 9 inside the casing 90 along a prescribed transport path; an ejection head 21 arranged inside the casing 90 and ejecting ink to the recording medium 9; a process chamber 40 having an inlet 40A and an outlet 40B arranged downstream from the ejection head 21 and for passage of the recording medium 9, the process chamber 40 communicating with the interior of the casing 90 through the inlet 40A; an irradiation unit 70 that irradiates the recording medium 9 inside the process chamber 40 with an ultraviolet ray; an inert gas supplier 50 that supplies an inert gas into the process chamber 40; and an air discharge part 60 that discharges atmosphere inside the process chamber 40 to the outside of the process chamber 40 and to the outside of the casing 90. An internal pressure in the process chamber 40 is less than an internal pressure in the casing 90.

摘要： An inkjet printer includes at least one head including a plurality of nozzles for ejecting ink toward a recording medium, a tank for supplying the ink to the head, an ink return part for feeding the ink from the head to the tank, and a pressure regulating part for performing a negative pressure reduction operation which increases the pressure in the tank when the pressure in the tank is not greater than a predetermined value. The inkjet printer further includes an operation sensing part for sensing the number of times or frequency of the negative pressure reduction operation performed by the pressure regulating part, and an error detection part for judging whether the ink return part is operating normally or not, based on a sensing signal from the operation sensing part. Thus, whether the ink is being circulated normally or not is checked without the provision of a sensor in an ink circulation path.

摘要： An inkjet printer includes at least one head for ejecting ink in the form of droplets, the ink being supplied from an ink tank. The head includes: a plurality of nozzles; an interior flow passage for supplying the ink to the nozzles; and a pressure adjustment part. The pressure adjustment part is connected to the interior flow passage. The pressure adjustment part has a damper space filled with a fixed amount of gas. The gas in the damper space is in contact with the ink filling the interior flow passage. When a negative pressure is developed in the nozzles by the ejection of the ink, the gas in the pressure adjustment part expands, so that the negative pressure in the nozzles is rapidly relieved. This prevents outside air from entering the nozzles.
