Recording device and recording method using halftone processing technique
A recording device includes a head including a first nozzle row that discharges a plurality of drawing inks; and a second nozzle row that discharges an overcoat ink posterior to the drawing inks, and also includes a dot-data generating unit that performs dot-data generating processing including halftone processing using a dither mask. When generating dot data used to perform recording in accordance with a first recording mode in which no nozzle that discharges the overcoat ink is assigned to part of pixels in a recording target region of the recording medium, the first recording mode being a recording mode using the second nozzle row, the dot-data generating unit generates the dot data by using a first overcoat dither mask having a threshold value set so as not to form a dot with the overcoat ink on the part of pixels.
Liquid ejection apparatus and system
A liquid ejection apparatus includes a liquid ejection head having an array of nozzles each configured to eject liquid, a storage, and a controller. The storage stores first data including distribution patterns and causes of an ejection failure and second data including causes of an ejection failure and maintenance manners. In a case where the nozzles include a failure nozzle, the controller determines a cause of a currently-occurring ejection failure based on the first data, perform maintenance in a first maintenance manner associated with the cause based on the second data. In a case where the currently-occurring ejection failure due to the cause has been recovered a predetermined number of times by maintenance in the first maintenance manner, the controller is configured to change the first maintenance manner associated with the cause to a second maintenance manner in the second data.

Method of manufacturing microstructure and method of manufacturing liquid ejection head
A microstructure including a minute structural part is manufactured by transferring a laminate including a photosensitive resin composition onto a substrate having an opening and patterning the laminate. The laminate includes a first layer that includes a first resin composition and a second layer that includes a second resin composition, each of the first and second resin compositions being a negative type photosensitive resin composition including a cationically polymerizable compound having an epoxy group. The laminate is transferred such that the second layer faces the substrate. The first resin composition is in a liquid state and the second resin composition is in a liquid state in the course of transferring the laminate.
LIQUID DISCHARGE APPARATUS AND WASTE LIQUID TANK
A liquid discharge apparatus includes a discharging unit configured to be capable of discharging a plurality of kinds of liquids onto a medium, and a waste liquid tank including a storage part configured to store a waste liquid of the liquid. The waste liquid tank includes a first inflow port and a second inflow port from which the waste liquid flows into the storage part, and a restriction portion located between the first inflow port and the second inflow port, and configured to restrict movement of the waste liquid in the storage part.
