METHOD OF OPERATING A FLEXOGRAPHIC PRINTING PRESS, FLEXOGRAPHIC PRINTING PRESS, SYSTEM, AND SLEEVE FOR A FLEXOGRAPHIC PRINTING FORME
A method operates a flexographic printing press. The flexographic printing press includes a printing cylinder carrying a sleeve with at least one flexographic printing forme or a flexographic printing cylinder and an impression cylinder. At least one parameter of the flexographic printing press is set. The sleeve is marked with an ID, the ID is detected in a flexographic printing unit of the flexographic printing press or in the flexographic printing press. Data saved in association with the ID are transmitted to the flexographic printing unit or to the flexographic printing press, and the data are used when the parameter is set. In this manner, a cost-efficient way of producing high-quality prints in an industrial flexographic printing process is obtained. In addition, the method provides further automation of the printing process.

METHOD OF OPERATING A FLEXOGRAPHIC PRINTING PRESS, FLEXOGRAPHIC PRINTING PRESS, SYSTEM, AND FLEXOGRAPHIC PRINTING FORME OR SLEEVE FOR A FLEXOGRAPHIC PRINTING FORME
A method of operating a flexographic printing press having a printing cylinder carrying a sleeve with at least one flexographic printing forme or a flexographic printing cylinder, and an impression cylinder, includes adjusting contact pressure between the printing cylinder or the flexographic printing cylinder and the impression cylinder by motor. The adjustment is made in an automated way as a function of a dot density of the flexographic printing forme, i.e. of a location-dependent density of printing elevations on the flexographic printing forme or data computationally derived therefrom. A cost-efficient way of producing high-quality prints in an industrial flexographic printing process is thus provided. In addition, the method advantageously provides further automation of the printing process. A flexographic printing press, a flexographic printing press system, and a flexographic printing forme or sleeve for a flexographic printing forme are also provided.

METHOD OF OPERATING A FLEXOGRAPHIC PRINTING PRESS, FLEXOGRAPHIC PRINTING PRESS, SYSTEM AND SLEEVE
A method of operating flexographic printing presses having an impression cylinder, printing cylinder carrying a sleeve with a flexographic printing forme or cylinder, uses a sensor adjusting print register of the printing forme or cylinder relative to a further printing forme or cylinder and/or adjusts color density and/or implements color inspection. An image of the sleeve surface with printing forme is recorded by a camera and processed before printing, locating a register mark and/or a color measurement field in terms of x-y positions. A sensor automatically moves for recording the register mark to the y-position of the register mark before adjusting to record the register mark and/or a sensor moves for recording the color measurement field to the y-position of the color measurement field before adjusting to record the color measurement field. Cost-efficient, high-quality industrial printing and further automation is provided.

PRINTING APPARATUS
A container printing apparatus has two or more inker devices. Each inker device has a print cylinder attached to a first end of a print shaft. Each print shaft has an outer shaft disposed about an inner shaft. The print shaft is configured to impart rotation to the print cylinder. Each inker device also has a first servomotor located at the second end of the print shaft distal from the first end of the print shaft and operably joined thereto. The first servomotor adjustably controls the position or orientation of a respective print cylinder. An automatic print correction detects a misregistration of ink transferred from one or more of the print cylinders onto a print blanket and a controller for controlling the first servomotor to correct the misregistration in response to data received from the print inspection device.

AUTO IMAGE REGISTRATION USING A PRINTER SYSTEM CONFIGURED FOR PRINTING ON SUBSTRATE HAVING AT LEAST ONE WIRELESS COMMUNICATION DEVICE
In some embodiments, a printer system may include a location sensor, a motor and driver assembly configured for adjusting a print position of a subsequent image on a substrate having a first side and a second side and at least one wireless communication device, and an optical sensor. Adjustment of the print position may be based on detection of the wireless communication device using the location sensor and a subsequent determination of whether the corresponding printed image is properly aligned with the wireless communication device using the optical sensor.
