A method, a printing device and a calibration module to check an alignment element of a printer by comparing a relative alignment of a calibration mark with respect to a reference mark, wherein the calibration mark indicates an alignment of the alignment element and the reference mark indicates an alignment of a printhead scanning direction of the printer.

Dot data for a boundary zone between metallic ink and color ink is changed to increase a time difference between a scan for applying the metallic ink and a scan for applying the color ink. With this change, a fusion time of the metallic ink is ensured, and the occurrence of an image defect is suppressed.

An ink jet recording apparatus according to the present invention includes: a conveying unit that conveys a recording medium; a pretreatment unit that performs corona treatment on a surface of the recording medium; an ink image forming unit configured to be able to form an ink image by applying an ink of at least two colors, the ink containing an anionic pigment; a brightness measuring unit that measures brightness of the ink image; and a corona treatment intensity changing unit configured to change a corona treatment intensity of the pretreatment unit based on a result of the brightness measuring unit.

A pagewide array (PWA) print bar of a printing device prints a calibration pattern on a print medium. The print bar is nominally perpendicular to a media advancement direction in which the print medium advances relative to the PWA print bar during printing. An image of the printed calibration pattern is optically scanned, and a skew angle by which the PWA print bar deviates from true perpendicular to the media advancement direction is calculated based on the optically scanned image. The printing device is calibrated to compensate for the calculated skew angle during subsequent printing.

A printing apparatus includes a printing unit configured to perform printing on a recording target, a projection unit configured to project a printing sample image onto the recording target, a detection unit configured to detect a user operation within a projection area into which the projection unit is configured to perform projection, and a control unit configured to control the printing unit based on a printing condition, wherein the control unit changes the printing condition, based on the user operation that is detected by the detection unit.

Systems and methods are provided for measuring a web. One embodiment is a measurement system that includes rollers which receive a web of print media marked with a printed job, a controller which determines that a segment of the web is stationary at the measurement system, an image measurement device that inspects the printed job, and a repositioning mechanism that repositions the segment within the measurement system relative to the image measurement device while portions of the web external to the measurement system remain stationary.

Examples of the present disclosure relate to a method for providing a status of a radiation emitter of a printing device, the method comprising image sensing at least part of a print agent after deposition onto a print substrate and after heating by the radiation emitter: obtaining, based on the image sensing, an irradiance applied on the heated print agent and providing a status of the radiation emitter in response to determining a deviation of the irradiance with respect to an expected irradiance.

Provided is a printing device that can accurately perform printing on a recording medium. The printing device includes: a frame member disposed to surround a nail tip; a printing unit configured to perform printing on the nail tip surrounded by the frame member; a communication part configured to acquire print information which is generated based on an image obtained by capturing the frame member and the nail tip and indicates a layout of printing to be applied to the nail tip in a printable region defined by the frame member; and a print control part configured to control the printing unit based on the acquired print information.

A method and device of providing a customized drink and/or printing on a drink.

A droplet ejecting apparatus includes a workpiece table configured to place a workpiece thereon, a droplet ejecting head configured to eject droplets onto the workpiece placed on the workpiece table, a Y-axis linear motor configured to move the workpiece table in a main scanning direction (Y-axis direction), a position detector configured to detect a position of a carriage mark, and a control unit configured to calculate the positional deviation amount in the main scanning direction between a detection position detected by the position detector and a reference position of the carriage mark and correct a droplet ejecting timing of the droplet ejecting head based on the positional deviation amount.
