The present invention provides a printing system with an apparatus for defect detection comprising a sensing unit for sensing a surface geometry or topology of a sheet and for generating data representative of that surface geometry or topology, a processor device for processing the data to detect and classify deformations, and a controller for controlling further progress of the sheet along the transport path of the printing system in dependence upon the deformations detected and classified by the processor device. Furthermore, the invention provides a corresponding method of detecting defects in a printing system.

A printing system comprising an apparatus for defect detection in a printing system. The printing system comprises, an image forming device, a sensing unit for sensing a surface geometry of a sheet to be printed and for generating data representative of that surface geometry, a processor device for processing the data; and a controller for controlling further progress of the sheet along a transport path of the printing system in dependence upon the deformations in the surface geometry of the sheet detected and classified by the processor device. The operating conditions the sheet is exposed to at the sensing unit are similar to the operating conditions the sheet is exposed at the image forming.

What is disclosed is a system for registering an object in a direct-to-object print system and a direct-to-object print system configured to operatively use various embodiments of the registration system of the present invention. In one embodiment, the marking system comprises a registration panel with a plurality of registration markings. A camera captures an image of the object in the object holder and the registration panel. A processor receives the image and analyzes the image to determine a position of the object relative to the markings on the registration panel. The processor determines whether the object is registered. If the object is registered, a controller causes the object holder to move the object past the printhead. Otherwise, if the object is not properly registered then the processor prevents the object from being printed and communicates a notification to a user that the object in the object holder is not registered.

An apparatus may include a housing defining a first opening, a second opening, and a cavity connecting the first opening to the second opening, the cavity may receive a user's extremity through the first opening and to allow egress through the second opening. An apparatus may include a visualization module configured to superimpose visual media equivalent to a desired tattoo onto the user's extremity within the cavity. An apparatus may include a printer module disposed within the cavity to apply the desired tattoo, the printer module including one or more print heads for administering temporary tattoo ink to apply the temporary tattoo to the user's extremity. An apparatus may include a user interface terminal configured to allow a user to select the temporary tattoo from among a number of candidate temporary tattoos and to adjust one or more properties of the temporary tattoo prior to application of the temporary tattoo.

A detection unit that detects the presence of an object that can come into contact with a liquid ejecting unit with relative movement between a medium and the liquid ejecting unit is provided with a piezoelectric film sensor that outputs an electrical signal when the object comes into contact with the detection unit, where the detection unit has first, second, and third plate portions formed so as to be continuous, the first plate portion is fixed so that the second and third plate portions are cantilevered, and the second plate portion, in a state where the piezoelectric film sensor is mounted thereon, is continuous with the first plate portion and is disposed diagonally with respect to the vertical direction of the medium, and the third plate portion is bent from the second plate portion and faces the medium leaving a gap between the third plate portion and the medium.

A conveyor includes a conveyance roller to convey a conveyed object, a pair of roller supports opposing to each other and supporting both ends of the conveyance roller in an axial direction thereof, a position sensor to detect a position of the conveyed object, and a sensor support supporting the position sensor. Each of the pair of roller supports has an insertion hole into which the sensor support is inserted. The insertion hole determines a position of the sensor support in a direction intersecting an insertion direction of the sensor support. The sensor support includes a positioning portion determining the position of the sensor support with respect to at least one of the pair of roller supports. The positioning portion determines the position of the sensor support in the insertion direction, a direction opposite to the insertion direction, and a rotational direction about an axis along the insertion direction.

There is provided a recording device including a transport section that transports paper along a support surface; a recording section; a determination region setting section; a liquid volume ratio calculation section; a determination section; and a recording position adjustment section that, when the determination section determines that the average value is larger than the threshold, adjusts a distance of the recording section from the support surface to a distance which is longer than a case in which the average value is not larger than the threshold.

A first score line camera captures an image of one sides of a plurality of tablets being conveyed by a conveyor drum. During transfer from the conveyor drum to a first conveyor belt, all the tablets are turned upside down while their directional properties are maintained. A second score line camera captures an image of opposite side of the tablets being conveyed by the first conveyor belt. Based on image data about both the front sides and back sides of the tablets acquired by the first and second score line cameras, a first ink-jet head performs front-side printing process on a front side of a tablet to conform to a predetermined direction relative to a score line in this front side. The second ink-jet head performs back-side printing process on a back side of a tablet to conform to a direction on the back side same as the predetermined direction.

A method to increase the print quality of a printer can include determining sensor data corresponding to a print image printed by a print head of the at least one print head of the printer onto the recording medium; determining, based on the sensor data, undulation information corresponding to unevenness of the recording medium, a distance between the one or more nozzles of the print head of the printer and the recording medium varying due to the unevenness; and printing, based on the undulation information, a subsequent print image with the print head of the printer. The printer can include at least one print head including one or more nozzles that are configured to fire ink droplets onto a recording medium to generate a print image on the recording medium.
