Disclosed is a workpiece processing apparatus that performs a predetermined processing on a workpiece. The workpiece processing apparatus includes: a workpiece table configured to place the workpiece thereon; a processor configured to process the workpiece placed on the workpiece table; a movement mechanism configured to relatively move the workpiece table and the processor; a position measuring device configured to measure a position of the movement mechanism; a detector configured to detect a position of the workpiece placed on the workpiece table; and a corrector configured to calculate a positional correction amount of the workpiece table based on a measurement result of the position measuring device and a detection result of the detector.

A method is for printing on a narrow face of a workpiece, in which surface information relating to at least some regions of at least one workpiece face adjoining the narrow face to be printed on is optically captured by a sensor device, the captured surface information is transferred to a print controller, and the print controller ascertains print information for controlling a printing unit on the basis of the captured surface information. The print information is used to control a printing process by which a narrow face decoration, which is matched to a decoration flow of the optically captured workpiece face, is printed on the narrow face.

A printing apparatus includes a medium accommodation portion that accommodates a medium, a medium discharge port for discharging the medium, a medium transport section that transports the medium, an ejection head that ejects a liquid to the medium to form an image, and an image detection section that detects the image. The printing apparatus has a first mode and a second mode, the first mode being a mode in which the medium transport section transports the medium in a direction from the medium accommodation portion toward the medium discharge port, and the ejection head ejects the liquid to the medium, and the second mode being a mode in which the medium transport section transports the medium in a direction from the medium discharge port toward the medium accommodation portion, and the image detection section detects image information of the image formed on the medium.

According to one embodiment, there is provided a printer including a print head, a platen roller, a sheet position sensor, an antenna, and a movable portion. The print head is configured to print on a strip-shaped sheet. The platen roller is configured to move the sheet pinched between the platen roller and the print head along a longitudinal direction of the sheet. The sheet position sensor is provided on a substrate disposed on an upstream side of the print head in a conveyance direction of the sheet, and is configured to detect a position of the sheet. The antenna is provided on the substrate and is configured to write information to a wireless tag provided on the sheet. The movable portion is configured to move the substrate along a width direction of the sheet.

A printing apparatus includes an imaging apparatus, a carriage, and a processing section. A sensor in the imaging apparatus has a plurality of pixels placed in a row direction and a column direction in the form of a matrix. The imaging apparatus is disposed in the carriage so that the row direction of the sensor and the direction in which the plurality of nozzles constituting each nozzle row are placed become parallel. The processing section causes ink to be discharged from a nozzle row to be adjusted to print a test pattern. By using a two-dimensional scale as a reference in detection of landing deviation, the processing section detects the landing deviation caused by the nozzle row to be adjusted, according to the imaged test pattern.

The ratios (Wp1/Wm1, Wp2/Wm2) of the pattern widths Wp1, Wp2 to the paper widths Wm1, Wm2 are obtained, respectively, after the first drying and after the second drying (Step S109). Then, in accordance with these ratios, a range (in other words, the width) in which the back print image G2 is to be printed is adjusted in the width direction Aw (Step S204). As a result, when the double-sided printing is performed on the continuous form paper M by performing drying every time when the image is printed on each of the surfaces Ma, Mb of the continuous form paper M, it is possible to suppress the difference in the ratios of the widths of the images G1, G2 to the width of the continuous form paper M between the surfaces Ma and Mb of the continuous form paper M.

There is provided a printing apparatus including: a holder configured to accommodate a printing medium; a conveyor configured to convey the printing medium along a conveying direction; a printer; a cutter configured to cut the printing medium; a first detector configured to detect front and rear ends of the printing medium; and a controller. A distance in the conveying direction between the first detector and the cutter is shorter than a length of one of media generated by dividing the printing medium into n-pieces of media. The controller is configured to: calculate a length in the conveying direction of the printing medium by using a result of the detecting of the front and rear ends, and set a cutting position of the printing medium; and cause the cutter to cut the printing medium at the set cutting position.

A detection device includes an electrostatic capacitance sensor including an electrode pair and being configured to detect electrostatic capacitance of a medium brought into contact with the electrode pair, and a first ultrasonic wave sensor including a first transmission unit configured to transmit an ultrasonic wave and a first reception unit configured to receive an ultrasonic wave transmitted from the first transmission unit. The transmission unit and the reception unit are positioned to sandwich the medium.

Disclosed is a printing device including at least one processor and a print head. The processor detects a nail region based on an image obtained by photographing a finger or a toe, sets at least a part of the detected nail region as a preceding print setting region, detects a region on which the preceding print is printed as a succeeding print region based on an image obtained by photographing the finger or the toe on which the preceding print is printed, sets a succeeding print region reference point corresponding to the succeeding print region, or sets a preceding print setting region reference point corresponding to the preceding print setting region and the succeeding print region reference point, and causes the print head to print a succeeding print on the nail region based on information on the preceding print setting region and a reference point that is set.

The present disclosure relates to the technical field of printing, and provides a digital printing press. The digital printing press includes a frame, and an unwinder, a driver, an inkjet printer, a curer and a winder that are arranged on the frame, where the driver drives a substrate to move from the unwinder to the winder along a substrate path, the inkjet printer and the curer are arranged above a printing segment of the substrate path, the printing segment of the substrate path is in the shape of an arch, and the arch bends toward the inkjet printer and the curer. The UV light from the curer can be reflected by the substrate to a position other than the inkjet printer as a result of the arched printing segment. UV light is prevented from entering the inkjet printer's nozzle, extending the inkjet printer's service life.
