A method and system for detecting one or more failing nozzles in an inkjet printhead of an inkjet printer for printing an image on a substrate and compensating failing nozzles, as well as for correcting colour uniformity of a printed image in inkjet printing an image on a substrate includes printing a first test pattern on a dedicated substrate, which is optically scanned and includes a system for the same. From the scan failing nozzles are identified, which are to be compensated by other nozzles. To these compensating nozzles compensated nozzle control data are allocated, which are used in printing a second test pattern that is also scanned and analysed for local deviations of colorimetric greyscale value. Corrected nozzle control data are allocated to the nozzles associated with the local deviation.

A nail polish application apparatus, comprising a mounting element comprising a capsule compartment adapted to receive one or more capsules containing a nail polish fluid wherein the mounting element is moveable by actuator(s) in longitudinal axis crossing a nail polish applying space and in lateral axis perpendicular to the longitudinal axis and is rotatable by the actuator(s) around the longitudinal axis, a pressure applying element adapted to apply pressure on a body portion of the capsule(s) installed in the capsule compartment wherein the body portion defines a reservoir containing a nail polish fluid, the pressure builds an internal pressure in the reservoir forcing extrusion of the nail polish fluid to a nail polish applying element integrated with the capsule(s), sensor(s) adapted to generate sensory data depicting the nail polish applying space and a control unit adapted to operate the actuator(s) and the pressure according to analysis of the sensory data.

A kit for usage by a nail polish application apparatus, the kit comprising one or more nail polish capsules. Each of the nail polish capsule(s) comprises a body portion defining a reservoir containing a nail polish fluid and a non-screw detachable cover having an integrated nail polish applying element. The non-screw detachable cover is mechanically coupled to an upper face of the body portion to seal an opening in the upper face.

A liquid droplet ejecting apparatus comprises a liquid droplet ejecting head which has a nozzle array composed of a plurality of nozzles arranged in a first direction, a relative movement mechanism which relatively moves the liquid droplet ejecting head and a recording medium in the first direction, and a controller. The controller controls the liquid droplet ejecting head and the relative movement mechanism to record, on the recording medium, a nonuniformity correction pattern in order to correct any dispersion in a liquid droplet ejection amount among the plurality of nozzles. The controller is configured, in order to record the nonuniformity correction pattern, such that the liquid droplet ejecting head is allowed to eject liquid droplets from at least the first nozzle to thereby record a first pattern group, the relative movement mechanism is allowed to relatively move the liquid droplet ejecting head and the recording medium in the first direction by a predetermined distance, and the liquid droplet ejecting head is allowed to eject the liquid droplets from at least the second nozzle to thereby record a second pattern group.

A system is disclosed. The system includes at least one physical memory device to store compensation logic and one or more processors coupled with the at least one physical memory device to execute the compensation logic to generate transfer functions for each of a plurality of color planes to compensate for non-functioning pel forming elements, wherein the transfer functions are generated based on ink deposition functions for groups of pel forming elements including functioning pel forming elements and the non-functioning pel forming elements, wherein the transfer functions transform input digital counts and the ink deposition functions represent output ink amount versus input digital count.

A printing apparatus includes a printing unit, a colorimetry unit, a data generation unit configured to generate color chart data, and a printing colorimetry control unit configured to control printing performed by the printing unit and colorimetry performed by the colorimetry unit, where the data generation unit acquires, from a first image represented by a first print job, a position of a first spot color contained in the first image and generates the color chart data having the first spot color patch disposed at a position corresponding to a position of the first spot color in the first image, and the printing colorimetry control unit causes the printing unit to print the color chart that is based on the color chart data and causes the colorimetry unit to measure the color of the color chart printed on the printing medium by the printing unit.

Methods, systems and computer readable media for color management are described. In some implementations, the method can include accessing one or more buildup curves associated with a combination of a substrate, one or more colorants and a colorant dispenser. The method can also include accessing a design file specifying a design and including one or more layer files each specifying a layer color. The method can further include generating, for each layer color, a corresponding colorization recipe based on the one or more buildup curves. The method can also include creating a production job instruction/metadata file having a link to the design instruction/metadata file and including parameters associated with the colorant dispensing job to be carried out using the design instruction/metadata file.

A processor identifies a specific part composed of a plurality of significant pixels in a mixed-color test image. Furthermore, the processor identifies a color vector. The color vector represents a vector in a color space from one of a color of the specific part in the mixed-color test image and a color of a reference area including a periphery of the specific part to the other. Furthermore, the processor determines which of a plurality of image creating portions of an image forming device corresponding to a plurality of developing colors, is a cause of an image defect, based on the color vector identified from the mixed-color test image.
