A recording device provides, when a first mode that is a recording mode for increasing concentration of black is selected, in a first nozzle row including first nozzles capable of discharging a first ink representing black by a single color or a mixed color, and a second nozzle row including second nozzles capable of discharging a second ink having a lower pigment concentration than a black ink and being an achromatic color, a nozzle unused region by a first nozzle not discharging a first ink and a second nozzle not discharging a second ink, between a first nozzle usage region including the first nozzle discharging the first ink onto the recording medium, and a second nozzle used region including the second nozzle for discharging the second ink onto a region of the recording medium onto which the first ink is discharged.

An example of a color management module is disclosed. The color management module is to generate a mapping from an incoming color space to a printer color space by a color pipeline. In the generation of the mapping, the color pipeline is adjusted so that the mapping of a target color associated with a first composition further includes adding a quantity of a second composition to the mapping of the target color. The second composition comprises a lower visibility than the first composition.

A first image has a first superimposing portion being a rear end portion of the first image. A second image has a second superimposing portion being a front end portion of the second image. A filter processing unit performs filter processing on the first superimposing portion and the second superimposing portion. A panoramic image has a superimposing region. The filter processing is processing for reducing change in image quality of the superimposing region occurring in a situation where the second superimposing portion overlaps the first superimposing portion in a misaligned manner.

An object of the present disclosure is to reduce density unevenness and streaks of an image that is printed in a case where it is not possible to implement sufficient correction only by the correction for a defective nozzle. One embodiment of the present invention is an image processing apparatus that performs processing for an input image for an image forming apparatus performing printing on a printing medium by using a print head in which a plurality of printing elements is arrayed, the image processing apparatus including: a storage unit configured to store density characteristic information indicating an output density for each tone for each of the printing elements; a target value acquisition unit configured to acquire a target characteristic indicating a target value for each tone; and a first correction unit configured to correct the input image based on the density characteristic information and the target value.

A printing apparatus includes a printing unit discharging a plurality of different pigmented inks onto a transfer member and forming an ink image, a processing unit performing processing such that each of the pigmented inks applied on the transfer member forms a layer, and a transfer unit transferring the ink image from the transfer member onto the printing medium conveyed by the conveyance unit. The pigmented inks include cyan, magenta, yellow, and black inks as pigmented inks of four basic colors, and at least one pigmented ink different from the pigmented inks of basic colors. A first ink at least one of the pigmented inks of the basic colors is applied onto the transfer member after a second ink is applied. The second ink is the pigmented ink different from the pigmented inks of the basic colors and has a color material density lower than that of the first ink.

A recording method includes: ejecting colored ink compositions that include a cyan ink composition, a magenta ink composition, a yellow ink composition, and a special color ink composition with a hue angle different from hue angles of the respective ink compositions from an ink jet head and causing the ink compositions to adhere to a recording medium; and causing a processing solution containing a coagulant for coagulating constituents of the colored ink compositions to adhere to the recording medium, the causing of the ink compositions to adhere is performed by performing scanning, in which the colored ink compositions are ejected while a relative position of the ink jet head with respect to the recording medium is changed in a scanning direction, a plurality of times, and a maximum distance of scanning performed once in the causing of the ink compositions to adhere is equal to or greater than 50 cm.

A system is disclosed. The system at least one physical memory device to store density control logic and one or more processors coupled with the at least one physical memory device, to execute the density control logic to generate first uncalibrated ink deposition data, receive first calibrated ink deposition data, generate a first transfer function based on the first uncalibrated ink deposition data and the first calibrated ink deposition data and transmit the first transfer function.

A recording method includes: ejecting colored ink compositions that include a light colored ink composition and a dark colored ink composition that belong to a same color system and have different color density from an ink jet head and causing the ink compositions to adhere to a recording medium; and causing a processing solution that contains a coagulant for coagulating constituents of the colored ink compositions to adhere to the recording medium, the causing of the ink compositions to adhere is performed by performing scanning, in which the colored ink compositions are ejected while a relative position of the ink jet head with respect to the recording medium is changed in a scanning direction, a plurality of times, and a width in the scanning direction of the recording medium is equal to or greater than 50 cm.

A printing apparatus includes a printing unit discharging a plurality of different pigmented inks onto a transfer member and forming an ink image, a processing unit performing processing such that each of the pigmented inks applied on the transfer member forms a layer, and a transfer unit transferring the ink image from the transfer member onto the printing medium conveyed by the conveyance unit. The pigmented inks include cyan, magenta, yellow, and black inks as pigmented inks of four basic colors, and at least one pigmented ink different from the pigmented inks of basic colors. A first ink at least one of the pigmented inks of the basic colors is applied onto the transfer member after a second ink is applied. The second ink is the pigmented ink different from the pigmented inks of the basic colors and has a color material density lower than that of the first ink.

An image forming apparatus includes a placement member, carriages, a support member, a driver and a hardware processor. The placement member has a placement surface. The carriages each include an image forming operation unit that performs an operation for forming an image on a recording medium placed on the placement surface. The support member supports the carriages such that the carriages are reciprocally movable along a predetermined movement path over the placement surface. The driver moves the carriages along the movement path independently from one another. In response to at least two of the carriages being moving along the movement path, the hardware processor controls the driver such that the number of carriages in a predetermined limit-imposed region of the movement path is equal to or less than a predetermined upper limit number that is less than the number of the carriages included in the image forming apparatus.
