摘要： An inkjet printer includes: a print execution unit that executes printing; and a controller that controls the print execution unit. The controller is configured to: determine whether a type of ink supplied by the ink supply unit is changed; determine whether to use a residual ink which is ink before change remaining in the ink flow path in response to be determined that the type of the ink is changed; control the print execution unit to execute new printing using the residual ink in response to be determined to use the residual ink for the printing; and execute a discarding process for discarding the residual ink before the new printing is performed in response to be determined to not use the residual ink for the printing.

摘要： An image processing apparatus configured to generate, using a target image data, multiple pieces of partial print data respectively for multiple partial printings such that, in a particular case where the color difference indicated by the evaluation value of the each of the partial images is larger than a particular reference value, a controller causes the image processing apparatus to identify, using the difference information, compensation target pixels including a pixel causing the color difference from among multiple pixels within the particular partial image, perform, using the difference information, a compensating process of converting a color of the compensation target pixel to a color of which color difference is small, and generate the partial print data using the particular partial image data to which the compensating process has been applied.

摘要： An image processing apparatus extracts provisional band data from image data. The apparatus calculates near white number for a target line. The near white number is number of pairs of first and second pixels. The first pixel is located on the target line, the second pixel is in positionally adjacent relation to the first pixel. At least one of the first pixel and the second pixel is a near white pixel. In a case where a prescribed border condition is met for the target line, the apparatus determines finalized band data so that a finalized band image includes at least part of the provisional band image, and has the target line as a borderline. In a case where a specific condition is met, the apparatus changes the target line to one of a plurality of candidate lines which is not selected as the target line.

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 multifunction peripheral includes a conveyance roller, a print engine, a scanner, and a controller. The controller is configured to perform: driving the conveyance roller to convey a recording medium and controlling the print engine to record, on the recording medium, a test image based on test image data with recording agent; after recording the test image, controlling the scanner to generate scan data of the test image recorded on the recording medium; after generating the scan data, extracting, based on the scan data and the test image data, stain data indicative of a stain caused by transfer of the recording agent from the conveyance roller to the recording medium; after extracting the stain data, generating correction data by removing the stain data from the scan data; and executing particular processing by using the correction data.

摘要： Color conversion information is used for carrying out a color conversion process to generate a converted image data. The color conversion information is configured as follows. Within a range from a predetermined first reference color value to a black input color value on a specific line, the closer to the black input color value a noticed input color value is, the larger a first output component value becomes. Within a first dark range, the closer to the black input color value the noticed input color value is, the smaller a second output component value becomes. Within a first light range, the closer to the black input color value the noticed input color value is, the larger the second output component value becomes. Within a first intermediate range, the second output component value is constant.
