The method of generating color sample data includes the step of generating the color sample data for preparing a color sample of a color included in a difference area between a color gamut in an equipment independent color space which is expressed by a first color expression apparatus and a color gamut in the equipment independent color space which is expressed by a second color expression apparatus using an output profile which expresses the color and corresponds to one of the first color expression apparatus and the second color expression apparatus configured to express a color in at least a part of the difference area out of a first output profile representing a correspondence relationship between a coordinate value in an output color space depending on the first color expression apparatus and a coordinate value in the equipment independent color space, and a second output profile representing a correspondence relationship between a coordinate value in an output color space depending on the second color expression apparatus and a coordinate value in the equipment independent color space based on a coordinate value in the difference area.

The width by which the first, second heads overlap each other cross-sectionally along the first direction is greater than the width by which the fifth, sixth heads overlap each other cross-sectionally along the first direction.

An example device includes a printhead including a first print element to print a first color to a print medium and a second print element to print a second color to the print medium. The second print element is spaced apart from the first print element by an offset distance. The device further includes a controller communicatively coupled to the printhead. The controller is to control the printhead to print an image, and in response to receiving a signal to stop printing the image, control the first print element to stop printing the first color to the print medium and control the second print element to continue printing the second color to the print medium.

A printing device is provided with a print head having a plurality of nozzles configured to eject ink droplets therefrom, a supplier configured to supply ink contained in a container to the print head, and a controller. The controller is configured to perform obtaining ink information having correlation with a height of a liquid surface of the ink contained in the container, obtaining subject image data representing an image to be printed, generating print data based on the subject image data, and causing the print head to eject ink droplets based on the print data. The generating includes adjusting the print data in accordance with the ink information.

A cartridge includes a liquid container and an adaptor. The liquid container has a liquid storage containing a liquid to be supplied to a printing apparatus, a liquid supply section configured to supply the liquid contained in the liquid storage to a liquid introduction section, and an adaptor mounting section. The adaptor is mounted on the adaptor mounting section and has a terminal placement section in which a cartridge-side terminal electrically connected to an apparatus-side terminal is disposed and an insertion aperture through which the liquid introduction section passes. The adaptor mounting section is provided with a mounting mechanism for mounting the adaptor, which has a predetermined constant shape.

In one example, a system to convey print media through a print zone in a printer includes an endless conveyor belt in a loop, a pair of drivers to circulate the conveyor belt through the print zone from opposite ends of the loop, an encoder to measure movement of the conveyor belt, and a controller programmed to control both drivers driving the conveyor belt based on measurements from the encoder.

A printing apparatus comprises: a print head comprising, for each of a plurality of types of inks, an ejection opening and pressure chamber, and configured to perform printing operation by ejecting the ink from the ejection opening; a circulation unit capable of circulating the ink of each ink type; a determination unit configured to determine an accumulated time for which a first type of ink is circulated by the circulation unit in the printing operation using the first type of ink and not using a second type of ink different from the first type of ink; and a control unit configured to perform control based on the determined accumulated time to cause the circulation unit to circulate at least the second type of ink among the plurality of types of inks in a case where the accumulated time is longer than a predetermined time.

A recording apparatus 101 includes a carriage 21 mounted with a liquid storage portion 46 and a recording head 22, the carriage 21 being movable to a visual check position, where liquid in the liquid storage portion 46 is visually checkable through a front surface 43F, and to a recording position, where the recording head 22 ejects the liquid to a medium, and light emitting units 81 and capable of illuminating the inside of the liquid storage portion 46 at least when the carriage 21 is positioned at the visual check position.

The present disclosure relates to a process for printing comprising the steps of selecting eight or fewer process colors from a known process ink color set, providing a color channel for the selected process colors from the known process ink color set, providing two or more spot color channels, wherein one or more of spot colors correspond to a non-selected process color of the process ink color set, applying a first ink limit and a first linearization to the one or more spot color channels to produce a color set including the non-selected process color of the known process ink color set, applying a second ink limit and a second linearization to the one or more spot color channels to produce a color set including the spot color, and optionally printing an image.

A cleaning method of a liquid ejection head where recording element substrates having an ejection orifice forming-face having ejection orifice arrays which are aligned, and at least one array ejects a different recording liquid than another, includes wiping and preliminary ejection. In the wiping, a wiping member is caused to move along and wipe the arrays. In the preliminary ejection, before the wiping of the entire ejection orifice forming-face is completed, preliminary ejection from the wiped ejection orifices is started. The wiping and preliminary ejection are sequentially performed from a recording element substrate at one end to a recording element substrate at the other end.
