A mounting unit, or printing system including a mounting unit, for mounting printing plate segments on a carrier sheet. The mounting unit includes a base for receiving the carrier sheet, at least two cameras, a controller for positioning the cameras relative to the base, and a computer connected to the controller and cameras. The computer is configured to receive a mounting file including a printing plate segment identifier, information regarding alignment of registration marks relative to the carrier sheet; and image data corresponding to a characteristic pattern associated with each printing plate segment. The unit is configured to display a composite image depicting the image data corresponding to the characteristic patterns in a predetermined arrangement of printing plate segment locations and orientations overlaid on an image of the carrier sheet from one of the at least two cameras.

A method of recording inspection data relating to print products formed on a printing press, the print products including a sequence of repeating format images, the method including the step of storing digital images of defective parts of a print product, wherein a compressed video stream of a regular sequence of the format images is stored for at least a clipping of the repeating format.

A printing system comprises a transport apparatus adapted to transport a flexible web along a process direction and first and second individually controllable ink jet imager units offset from one another along the process direction. Each of the first imager unit and the second imager unit includes a first portion operable to print on a first portion of the web and a second portion operable to print on the second portion of the web wherein each of the first portion and second portion of the first and second imager units is stationary along the process direction and the lateral direction.

Printing machine, for printing a laminar web, comprising a feeding unit (10) defining a printing area (A); an inkjet printing station (20) comprising a plurality of inkjet printing modules (21) slidably arranged along a transverse guide (22); a positioning device (30) adapted to precisely slide the inkjet printing modules (21) along the transverse guide (22); wherein each inkjet printing module (21) includes a first coupling (31) and is independent from other inkjet printing modules (21) allowing an independent movement of each inkjet printing module (21) along the transverse guide (22); and the positioning device (30) includes a second coupling (32) complementary to each first coupling (31), the second coupling (32) being releasably engageable to each first coupling (31) in an automatic manner, the positioning device (30) being configured to precisely slide each inkjet printing module (21) engaged thereto, along the transverse guide (22).

In some examples, a print control strip includes at least one control patch configured as an element for color management. The element for color management may be configured to measure a color density and/or at least one spectral value and/or an area of coverage of individual printed printing colors. The print control strip further includes at least one control patch configured as a printing mark. The printing mark is configured for aligning a substrate in a transport direction and/or in a transverse direction. Additionally, the print control strip includes at least one control patch configured as a plate recognition patch. The plate recognition patch is configured to assign at least one printing color used to a printing plate and/or to an application mechanism and/or is configured for such assignment.

A printed substrate is provided. The printed substrate includes a plurality of color bars printed on a substrate, a space between each of the plurality of color bars and an image printed in the space between at least two of the color bars. An embedded color bar and a method of printing an embedded color bar are also provided.

A device for handling foil for use in a printing process during which portions of a layer of the foil are transferred to a substrate comprises a foil input unit for inputting at least one foil web to the device, a number of rotatable shafts and bars for directing the at least one foil web to the printing press and retrieving at least one used foil web from the printing press, an arrangement for controlling operation of the device, and a web tension feedback unit for detecting at least one characteristic related to an actual web tension during operation of the device so as to realize web tension control by adjusting motion and/or positioning of at least one of the rotatable shafts and bars in case the characteristic appears to deviate from a reference related to a set web tension.

A method of adjusting the print repeat length of a print image in a multicolor rotary printing machine, particularly a flexographic printing press, having a central impression cylinder, a first plate cylinder, and a second plate cylinder, including modifying the peripheral velocity of the first plate cylinder and the peripheral velocity of the second plate cylinder during printing operation, relative to the peripheral velocity of the central impression cylinder, and adjusting the longitudinal register of the first plate cylinder having the modified peripheral velocity and the longitudinal register of the second plate cylinder having the modified peripheral velocity.

An apparatus and method for use in capturing image data of an output of a printing device during a print run, the method comprising capturing a first portion of image data of a first spread, capturing a second portion of image data of a second spread, wherein the location of the second portion of image data on the second spread is different from the location of the first portion of image data on the first spread, and combining the first portion with the second portion to generate oversampled image data.

A feedback information generation method for a solder inspection apparatus includes: receiving an input of information on the number of buffers which are disposed between the solder inspection apparatus and a screen printer for printing solder on printed circuit boards and are configured to support the printed circuit boards to be introduced into the solder inspection apparatus so as to put the printed circuit boards on standby; generating feedback information by using the input information and an inspection result of the printed circuit boards by the solder inspection apparatus; and transmitting the feedback information to the screen printer. Feedback information may be generated in consideration of the number of buffers, thereby preventing the feedback information from being excessively generated as well as ensuring the accuracy of the feedback information.
