A recording device includes a recording head in which a plurality of nozzle rows are arranged in a predetermined direction that include a first nozzle row including a plurality of nozzles for ejecting ink having a predetermined color, and a second nozzle row including a plurality of nozzles for ejecting ink having an identical color to the predetermined color, and a control unit configured to control ejection of ink by the nozzle, wherein the control unit, when a test pattern for an inspection of a missing dot due to an ejecting defect of the nozzle is recorded on a recording medium, records a dot pattern, that is an individual element that forms the test pattern, so that ink ejected from a nozzle of the first nozzle row, and ink ejected from a nozzle of the second nozzle row overlap.

Recording device and recording method

A recording device includes a recording head including a plurality of nozzle rows of a plurality of nozzles for ejecting a same color ink, a detector configured to detect, from among the plurality of nozzles, a defective nozzle having an ejecting defect, and a control unit configured to determine whether the recording head is in an error state, based on a detection result from the detector. The control unit determines that the recording head is in the error state when, among the plurality of nozzles having a specific positional relationship in which the nozzles are configured to compensate for each other's ejection, at least a predetermined number the nozzles, which is greater than one, is the defective nozzle.

Recording device and recording head error determining method

A printing control apparatus configured to control a printing apparatus including an acquisition unit configured to acquire discharge characteristic information including a characteristic of discharging ink for each of nozzles, a correction amount calculation unit configured to calculate a correction amount for correcting an amount of the ink discharged onto a printing medium based on the discharge characteristic information for each of printing modes having mutually different relative movement amounts of the sub scanning movements, and a printing data generation unit configured to generate printing data for executing printing in accordance with the printing mode based on the correction amount.

Printing control apparatus, printing control system, and printing control method

An apparatus for cutting an electrical wiring line includes a laser generator for generating a laser beam, an optical beam branching element for branching a laser beam generated by the laser generator into a plurality of branch beams, and a condenser element for condensing the branch beams branched by the optical beam branching element (the optical beam branching element can also serve as the condenser element). The condenser element may be a condenser lens which is separate from the optical beam branching element. The power and the focal depth of the branch beam may be adjusted. When the substrate has a transparency to the laser beam, the branch beam is directed to the electrical wiring line formed on the substrate from the opposite side to the surface having the electrical wiring line.

Method and apparatus for cutting electrical wiring line on a substrate, and method and apparatus for manufacturing electronic device

An electrooptic device includes a first substrate, wiringprovided along one side of the first substrateto extend to another side crossing the one side, and a coating layercoating the wiring. Conceivable examples of the electrooptic device include a liquid crystal device, and an EL device. In the liquid crystal device, the coating layercan be formed by a sealing material for bonding together the first substrateand a second substrateopposed to each other. The wiringis coated with the coating layerto be cut off from contact with the outside air.

A liquid crystal display device is provided with a plurality of color filters R, G, and B corresponding to colors of red base, green base, and blue base, respectively, and a reflection layer placed on the side opposite to observation side with respect to a liquid crystal and color filters A plurality of fine crest portions and trough portions are formed on the surface of the reflection layer In the reflection layer the mirror reflectivity of the region facing the color filter of at least one color is different from the mirror reflectivities of the regions facing the color filters of the other colors. Specifically, the mirror reflectivity of the region facing the blue-based color filter B in the reflection layer is higher than the mirror reflectivities of the regions facing the red-based and green-based color filters R and G in the reflection layer
