The driving order of driving blocks is controlled so that ink landing positions from driving blocks differ from each other in multiple scans. Recording data is generated so that, of pixels where ink is discharged in one scan, the number of pixels adjacent at both sides in the scanning direction to pixels where ink is discharged in another scan is greater than the number of pixels not adjacent at both sides in the scanning direction to pixels where ink is discharged the other scan.

The recording method includes ejecting a first ink for image forming and a substantially colorless second ink onto a recording surface of a recording medium at an ejecting unit, and controlling ejecting operations of the first ink and the second ink in the ejecting unit. The second ink is permeation ink configured to permeate the first ink into the recording medium from the recording surface to an opposite surface of the recording medium, and the opposite surface is opposite the recording surface. The controlling includes performing a plurality of ejecting operations of the first ink with respect to one ejecting operation of the second ink, so that at least a part of a landing position of the second ink and a landing position of the first ink overlap on the recording medium.

A recording apparatus includes an ejecting unit configured to eject a first ink for image forming and a substantially colorless second ink onto a recording surface of a recording medium, and a control unit configured to control ejecting operations of the first ink and the second ink. The second ink is permeation ink configured to permeate the first ink into the recording medium from the recording surface to an opposite surface of the recording medium. The control unit controls the ejecting unit to perform a plurality of ejecting operations of the first ink with respect to one ejecting operation of the second ink. An ejecting amount of the first ink ejected when the ejecting unit ejects both of the first ink and the second ink is greater than an ejecting amount of the first ink ejected when the ejecting unit ejects only the first ink without ejecting the second ink.

A method in a printer comprising a first printhead to dispense a first printing fluid and a second printhead to dispense a second printing fluid, the first and second printheads being arranged on a common scan axis that is substantially perpendicular to a media advance direction. The method comprises controlling movement of the first and second printheads relative to a media being printed, between a first index position and a second index position, the second index position being downstream of the first index position, and wherein the movement occurs during a time period between a forward scan and a reverse scan of the first and second printheads across a media being printed.

A printing control device, a printing device and a non-transitory computer-readable recording medium are provided. It is possible to set a scan width of a head to a user's desired width. A printing control unit controls a printing device having a head, and includes an input receiving unit for receiving a scan width information representing a width over which the head will move during scanning, and the scan width information is information representing a user's desired numerical value.

White-balance is improved when printing on colored media, while minimizing the time and use of costly materials required by present approaches. In an embodiment, the typical solid white fill or background layer is altered by including in the white layer one or more of the other colors already available in the printer to shade this layer. Thus, a small amount of cyan, for example, helps balance a pink-ish (red) media; yellow is used for blue media; and magenta is used for green media; as well as combinations thereof. A combination of transparent process inks and opaque white helps to maintain brightness (luminosity).

A printer according to this invention includes a print head, a carriage, a recovery unit, and a controller. The controller causes a recovery operation to be performed based on a total value of two values. Assuming that front and rear arrays of discharge port arrays during outbound movement of the carriage are defined as first and second arrays, respectively, the first value is obtained by multiplying a sum of an amount of ink discharged from the first array during outbound movement of the carriage and an amount of ink discharged from the second array during homebound movement of the carriage by a first coefficient, and the second value is obtained by multiplying a sum of an amount of ink discharged from the second array during outbound movement of the carriage and an amount of ink discharged from the first array during homebound movement of the carriage by a second coefficient.

A printing apparatus includes a carriage unit, and carries out printing on a recording medium while transporting the recording medium. The carriage unit includes a first head that discharges an ink and a second head that discharges an ink of the same color, and the second head is disposed so as to be adjacent to the first head in an x axis direction, and to overlap with the first head in a y axis direction. In an outgoing path in the reciprocation of the carriage unit, a printing density of a first image, which the first head prints, gradually decreases toward a downstream side in a transport direction of the recording medium, and the first image includes a dot group, in which at least two dots formed using the ink from the first nozzles are linked to one another in the x axis direction. In addition, in a return path in the reciprocation of the carriage unit, the second nozzles print a second image, which supplements a decrease in the printing density of the first image.

Provided is a dot recording apparatus in which a first dot group is formed using a first nozzle group, a second dot group is formed using a second nozzle group, a third dot group is formed using a third nozzle group, of which the distance from the first nozzle group in a direction is a first nozzle row distance, a fourth dot group is formed using a fourth nozzle group, of which the distance from the second nozzle group in a direction is a second nozzle row distance, which differs from the first nozzle row distance, and inclination of the main scanning direction and a nozzle row are calculated on the basis of a distance in the main scanning direction from the first dot group up to the third dot group, and a distance in the main scanning direction from the second dot group up to the fourth dot group.

An imaging apparatus includes a print engine having a printhead that generates ink drops, and a printhead carrier that carries the printhead in a first direction and in a second direction. A controller determines an initial print direction based on ink drop information obtained by printing patches in the first direction and in the second direction. The controller is operatively coupled to the print engine to print an image based on the initial print direction.
