A liquid ejecting apparatus includes: a head having nozzles; a conveyor configured to convey a recording medium; and a controller. The controller executes: a recording processing of conveying the recording medium by the conveyor and ejecting liquid from the nozzles with respect to the recording medium based on image data; a flushing processing of discharging the liquid from the nozzles with respect to a flushing area, based on flushing data different from the image data; and a first determining processing of determining, based on the image data, whether a time interval after completion of a first recording processing and until start of a second recording processing exceeds a threshold value.

A method for printing sheet-type substrates to prevent streaks during the ink-jet paint coating of substrates, includes moving a substrate in a feed direction past an application device by means of a conveying device, applying with the application device, during the movement of the substrate, a fluid application material drop by drop to the surface of the substrate in a pattern with a pre-defined contour, in particular leaving out regions, through a plurality of ink-jet nozzles arranged in a row transversely to the feed direction, in response to computer-controlled switching signals, and during the application of the pattern and during the movement of the substrate, moving the ink-jet nozzles back and forth transversely to the feed direction, preferably in the longitudinal direction of the arranged row of ink-jet nozzles, such that the paths travelled by the nozzles over the substrate by the overlap of the movement back and forth with the movement in the feed direction have direction components running perpendicular to the feed direction.

Applying a metallic ink, then applying a chromatic color ink with high dye aggregability, and then applying a chromatic color ink with low dye aggregability improve the color development of the chromatic color ink with low dye aggregability.

An image processing method includes a first conversion step, a second conversion step that, using a second conversion table for converting input image data represented by a second color space to output image data represented by the second color space, converts image data of a second region for which recording conditions are different from a first region in a second image data, and a recording data generating step that generates recording data based on third image data including image data of a first region in the second image data and image data of the second region after conversion using the second conversion table. When adjusting an ink amount, the ink amount is not adjusted in the second conversion step and is adjusted in the first conversion step.

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.

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.

An ink jet method includes causing a treatment liquid to adhere to a recording medium; a white ink to adhere to the recording medium; and a non-white ink to adhere to the recording medium. The treatment liquid, white ink, and non-white ink are applied by main scans of a recording head and sub-scans of the recording medium that intersect the main scans. The recording head includes a first nozzle group arranged in the sub-scanning direction and discharging the treatment liquid, a second nozzle group arranged in the sub-scanning direction and discharging the white ink, and a third nozzle group arranged in the sub-scanning direction and discharging the non-white ink. The second and third nozzle groups have non-overlapping portions in the main scanning direction, and one or both of the second and third nozzle groups have a portion overlapping the first nozzle group in the main scanning direction.

In an image processing device, a controller is configured to perform: selecting; generating; and outputting. The selecting selects a target partial image one by one from a plurality of partial images. The target partial image is represented by target partial image data. The generating generates partial print data for a partial print by executing an image process on the target partial image data. The partial print forms the target partial image while moving a print head in a printing direction. The partial print forms the target partial image while moving a print head in a printing direction. The image process includes a color conversion process. The color conversion process is executed on the target partial image data using one of a first profile and a second profile selected in accordance with the printing direction set for the partial print. The outputting outputs the partial print data to the printer.

In an example a system includes a carriage with a print head receiving station, a color variation engine, and a delay engine. The color variation engine identifies a potential color variation condition corresponding to an area fill region. The delay engine applies a carriage delay strategy according to the identified potential color variation condition and the size of the area fill region.

A recording system records a recording image based on image data by repeating a pass operation in which a nozzle row discharges ink while moving relatively to a recording medium in a main scanning direction and a transport operation in which the nozzle row and the recording medium relatively move in a sub scanning direction intersecting the main scanning direction. The recording system includes a code detecting unit that detects an area where code information included in the image data is located, and a recording controller that controls the pass operation and the transport operation based on the image data and a result of the detection by the code detecting unit. The recording controller controls such that the number of times of the pass operation of recording the area is smaller than that of the pass operation of recording an area adjacent to the area in the main scanning direction.
