Abstract: A device and method for the control and management of the printing parameters of a printing machine, particularly with a plurality of consecutive printing processes, is presented. The device and method include at least one video camera associable with a printing and conversion assembly and movable along a motorized guide in order to acquire a print medium. An image processor is functionally associated with the video camera to search, recognize and measure on the image of the print medium acquired by the video camera the printing values of at least one reference register mark reproduced on the print medium. The image processor is functionally connected to a unit for the actuation of the printing and conversion assembly to correct and restabilize the printing values according to the difference between the printing values measured by the image processor and the desired theoretical printing values.

Abstract: A magazine for printing and converting heads for printing machines, comprising at least one containment body which is adapted to be arranged in close proximity to a printing machine and is adapted to accommodate a plurality of printing and converting heads, a carriage being provided for conveying the printing and converting heads from the at least one containment body to the printing machine and from the printing machine to the at least one containment body.

Abstract: A magazine for printing units for printing machines, comprising at least one track which is adapted to be arranged proximate to a printing machine and allows engagement of a plurality of printing units, further comprising at least one parking track, which is connected to the at least one track, in order to allow the parking of at least one printing unit which is coupled to the at least one track.

Abstract: A multiconfiguration printing assembly comprising a first inking assembly for a first type of printing, a second inking assembly for a second type of printing, a printing roller related to the first type of printing and a printing roller related to the second type of printing, a single contrast roller being provided and being common to the printing rollers.

Abstract: An inking device for a printing roller for flexographic, rotogravure or offset printing, comprising an ink container with a closed doctor, and a printing roller onto which the ink is to be transferred from the ink container, the device further comprising, within the ink container with closed doctor, a rubber roller, which is meant to make contact with the printing roller in order to transfer controlled doses of ink to cells formed on the surface of the printing roller.

Abstract: A printing unit with removable printing cylinder, comprising two outer shoulders which are adapted to constitute a supporting frame for a printing cylinder, a first pair of arms and a second pair of arms which are pivoted at an upper end of each one of the shoulders and form a seat for accommodating the printing cylinder, elements for locking the printing cylinder being provided in order to retain the printing cylinder so that it rests on the first and second pairs of arms.

Abstract: A printing unit with more easily removable components, comprising two outer shoulders, which are adapted to support a printing cylinder, and two inner shoulders, which are pivoted to the outer shoulders so as to pass from an open position to a closed active printing position, the pair of inner shoulders supporting an inking cylinder, a tray which is suitable to contain the ink and is arranged below the inking cylinder, and a cylinder bearing the type, the closure position of the two inner shoulders being such as to move the cylinder bearing the type into abutment against the printing cylinder in order to perform printing and such as to move the inking cylinder into abutment against the cylinder bearing the type.
