摘要： There is provide an image processing apparatus including a carriage with a recording head and a sensor mounted thereon, a conveyer, and a controller. The controller carries out: acquiring a recording data, a front edge margin, and a tail edge margin, determining whether or not at least one of first and second reference values is less than a threshold value, and a positioning process. When at least one of the first and second reference values is less than the threshold value, then the controller carries out: a front edge detecting process, a first recording preparation process, and a recording process. When at least one of the first and second reference values is not less than the threshold value, then the controller carries out: a second recording preparation process, and the recording process.

摘要： A printing apparatus includes a print execution section and a controller. The print execution section includes: a printing head having nozzles from which ink is discharged; a main-scan section configured to execute main-scan in which the printing head moves along a main-scan direction relative to a printing medium; and a sub-scan section configured to execute sub-scan in which the printing medium moves along a sub-scan direction relative to the printing head. The controller obtains object image data indicating an object image formed by pixels, generates pieces of partial printing data by processing the object image data in an order from a downstream side toward an upstream side in the sub-scan direction, and causes the print execution section to execute, a plurality of times, the sub-scan and partial printing in which ink is discharged from the printing head during the main-scan by use of the pieces of partial printing data.

摘要： There is provided an image recording apparatus including: a conveyor; a carriage; a recording head; and a controller. In a case that a moving direction in the scanning direction of the carriage in one of the two continuous recording passes is same as a moving direction in the scanning direction of the carriage in the other of the two continuous recording passes, the controller is configured to make a length in the conveyance direction of the overlap area to be a first length. In a case that the moving direction in the scanning direction of the carriage in the one of the two continuous recording passes is different from the moving direction in the scanning direction of the carriage in the other of the two continuous recording passes, the controller is configured to make the length in the conveyance direction of the overlap area to be a second length.

摘要： A liquid discharging apparatus includes: a channel unit having a nozzle and an individual channel; an actuator applying pressure to liquid in the individual channel to discharge the liquid from the nozzle; a driving circuit electrically connected to the actuator and supplying driving signal to the actuator; and a controller. In a case of determining that a single-sided recording is to be executed, the controller supplies the driving signal corresponding to each of gradation values for each of pixels when discharging the liquid toward one of a first surface and a second surface of a recording medium; in a case of determining that the double-sided recording is to be executed, the controller supplies the driving signal corresponding to each of the gradation values for each of the pixels when discharging the liquid toward the first surface and when discharging the liquid toward the second surface.

摘要： A controller is configured to: when both a first conveyor and a second conveyor are operating concurrently, determine whether a reference current value exceeds a threshold value, the reference current value being obtained based on at least one of a first driving current that is a driving current of the first conveyor and a second driving current that is a driving current of the second conveyor; in response to determining that the reference current value exceeds the threshold value, continue an operation of an earlier-driven conveyor that is one of the first conveyor and the second conveyor that is started at earlier timing, and temporarily stop an operation of a later-driven conveyor that is one of the first conveyor and the second conveyor that is started at later timing; and after a driving current of the earlier-driven conveyor drops to a particular standard, restart the operation of the later-driven conveyor.

摘要： In an image processing apparatus, a processor sets a target printing method for printing a target image to one of a bidirectional printing method and a unidirectional printing method. In a case where the bidirectional printing method is set as the target printing method: the processor executes both a first generation process and a second generation process. The first generation process generates first partial print data by converting a set of partial image data using a first color conversion profile. The second generation process generates second partial print data by converting another set of partial image data using a second color conversion profile. In a case where the unidirectional printing method is set as the target printing method, the processor executes a third generation process generating third partial print data by converting a set of partial image data using a third color conversion profile.

摘要： An image processing device is communicable with a printer and includes a controller. The printer is configured to repeatedly and alternately execute a partial print and a sub scan to form an image. The image is made up of a plurality of partial images arranged in a sub scanning direction. The partial print forms a target partial image while performing a main scan. The controller is configured to perform: setting; generating; and outputting. The setting sets a printing direction for the partial print to one of first and second directions. The generating generates partial print data for the partial print by executing a color conversion process on target partial image data using a color conversion profile. The color conversion profile is selected from first and second profiles respectively corresponding to the first and second directions. The outputting outputs the partial print data and direction information specifying the printing direction.

摘要： There is provided a liquid discharge apparatus including a conveyer, a carriage, a head and a controller. In a case of recording an image on a recording medium, the controller executes: obtaining information regarding a supply state of liquid from a liquid tank to the head in a case of executing each of recording passes; determining a moving velocity of the carriage with respect to each of the recording passes, based on the obtained information regarding the supply state; and adjusting a conveyance amount, by which the recording medium is conveyed in each of conveying operations, depending on moving velocities of the carriage determined with respect to two continuous recording passes, respectively, included in the recording passes, so as to adjust length in the conveyance direction of an overlap area in which recording areas by the two continuous recording passes overlap with each other.

摘要： There is provided an image recording apparatus, including: a conveyer; a carriage; a recording head having at least three nozzle rows; and a controller. When a moving direction of the carriage in one of two continuous recording passes is different from that in the other of the two continuous recording passes, the image recording apparatus conveys a recording medium in the conveyance direction so that two recording areas partially overlap with each other. When a line image, which belongs to an overlap area, is recorded, the image recording apparatus executes recording so that the two continuos recording passes complement each other, and forms at least part of dots in the line image in accordance with a landing order different from a landing order used when the image is recorded in a non-overlap area included in the recording areas and different from the overlap area.
