A liquid application apparatus sequentially moves to a plurality of regions to which a region to be applied with liquid is divided and discharges liquid on basis of an image pattern corresponding to each of the plurality of regions. The liquid application apparatus includes processing circuitry configured to: calculate a deviation amount between a first region on which an image pattern is applied by the liquid application apparatus and a second region to which the liquid application apparatus moves from the first region; and correct an image pattern corresponding to the second region on basis of the deviation amount calculated.

In a case where a plurality of times of relative movement between a board and a liquid jet head are performed and liquid is jetted to the board from the liquid jet head during each relative movement to form a pattern on the board, a first relative movement is performed and the liquid is jetted from the liquid jet head to form a first pattern element on the board, a second relative movement is performed and the liquid is jetted from the liquid jet head to form a second pattern element at a position in contact with the first pattern element and to form the pattern including the first pattern element and the second pattern element, and a relative movement speed lower than a relative movement speed of the second relative movement is applied to the first relative movement.

The present disclosure relates to an ink jetting apparatus with multi-nozzles, the apparatus including a liquid droplet generating unit configured to generate liquid droplets from ink and jet the liquid droplets through the multi-nozzles, and an evaporation control unit configured to guide the liquid droplets jetted from the multi-nozzles to protect the liquid droplets from thermal and physical disturbance and control evaporation of the liquid droplets.

A liquid ejecting apparatus includes a head unit that ejects ink onto a medium, a transport unit that transports the medium, and a control unit that forms an adjustment pattern on the medium, and the control unit forms, as the adjustment pattern, a pattern including a first pattern that is formed in a transport direction, a plurality of scales that are formed in the transport direction, and a second pattern that is formed at a position corresponding to the scales in the transport direction while the position thereof in a main-scanning direction that intersects the transport direction is changed.

The disclosed spray deposition systems and methods use spray charging and discharging techniques to assist with digital deposition of spray droplets on a substrate. For example, the disclosed systems and methods have a charging system that generates spray droplets from a spray generator and charges the droplets. Focusing electrodes help to collimate the droplets into a tight droplet stream and, optionally, steering electrodes help direct the tight droplet stream. A charge removal system neutralizes or removes the charge from the droplets, either during the deposition of the droplets on a substrate or after the droplets have been deposited on a substrate.

[Problem to be Solved] To provide a tablet printing apparatus and a tablet printing method that can perform printing with high quality by ejecting ink droplets to a tablet with a various posture from a plurality of nozzles. [Solution] A tablet printing apparatus includes: inclined posture detector (23, 100) that detects an inclined posture of a conveyed tablet with respect to a conveying surface; a printer including an inkjet head 21 equipped with a plurality of nozzles for ejecting an ink droplet, the printer performing printing on the conveyed tablet by ejecting ink to the conveyed tablet from the plurality of nozzles; and a controller 100 for adjusting preset printing data corresponding to an inclined posture of the tablet detected by the inclined posture detector such that predetermined printing is performed on the tablet, wherein the printer performs printing on the tablet based on printing data adjusted by the printing data adjuster.

A droplet ejecting apparatus includes: an ejecting section having a plurality of nozzles arranged along an intersecting direction with a transport direction of a recording medium. Each nozzle ejects a main droplet and a sub-droplet smaller than the main droplet consecutively. Each nozzle can change a deflection amount in an ejecting direction of the main droplet along the intersecting direction. A control section performs, in a case where a defective nozzle exists in the nozzles, a control of deflecting the ejecting directions of the main droplets ejected from a nozzle positioned within a predetermined distance from the defective nozzle toward a landing position of a main droplet that should have ejected from the defective nozzle.

A liquid ejecting device includes: a head unit including a first channel member formed with a first channel having a first communication port; and a mounting unit including a positioning part and a second channel member formed with a second channel having a second communication port. The liquid ejecting device is switchable between: a first state in which the head unit is not positioned relative to the mounting unit, and the first communication port and the second communication port are not in communication with each other; and a second state in which the head unit is positioned relative to the mounting unit, and the first communication port and the second communication port are in communication with each other. The liquid ejecting device is shifted from the first state to the second state as the second channel member and the positioning part are moved relative to the head unit.

A recording apparatus, having a head including first nozzles and second nozzles, a carriage, a relative-movement device, a first reservoir, a second reservoir, and a controller, is provided. The controller repeats one of a set of a multiple-liquids recording pass, where liquids in different types are discharged from the first nozzles and the second nozzles, and a first relative-movement action, where the head and a recording medium are moved relatively in a relative-movement direction, and a set of a single-liquid recording pass, where a liquid in a same type is discharged from the first nozzles and the second nozzles, and a second relative-movement action, where the head and the recording medium are moved relatively in the relative-movement direction. A resolution of an image recorded in the single-liquid recording pass is higher than a resolution of an image recorded in the multiple-liquids recording pass in the relative-movement direction.

A high precision printing method taking into consideration the variance in the thickness of a printing target. An ink-jet printing method, including: (i) measuring a distance between a printing target and at least one nozzle; (ii) measuring a flying speed and a flying angle of an ink(a) discharged from the at least one nozzle; (iii) printing a test substrate with an ink to identify a location on which an ink(b) is spotted, and calculating a thickness-related displacement that is a displacement from the location on which the ink is spotted, based on a thickness difference between the printing target and the test substrate from results obtained in Step (i), and the flying speed and the flying angle of the ink(a) obtained in Step (ii); and (iv) discharging an ink(c) from the at least one nozzle to achieve actual printing of the printing target with the ink(c) while correcting the thickness-related displacement.
