A printing system for printing on a substrate, comprises a movable intermediate transfer member in the form of a flexible, substantially inextensible, belt guided to follow a closed path, an image forming station for depositing droplets of a liquid ink onto an outer surface of the belt to form an ink image, a drying station for drying the ink image on the belt to leave an ink residue film on the outer surface of the belt, first and second impression stations spaced from one another in the direction of movement of the belt, each impression station comprising an impression cylinder for supporting and transporting the substrate and a pressure cylinder carrying a compressible blanket for urging the belt against the substrate supported on the impression cylinder, and a transport system for transporting the substrate from the first impression station to the second impression station. The pressure cylinder of at least the first impression station is movable between a first position in which the belt is urged towards the impression cylinder to cause the residue film on the outer surface of the belt to be transferred onto the front side of the substrate supported on the impression cylinder, and a second position in which the belt is spaced from the impression cylinder to allow the ink image on the belt to pass through the first impression station and arrive intact at the second impression station for transfer onto the reverse side of the substrate supported on the second impression cylinder.

Digital printing system

A system printing comprises: a movable intermediate transfer member in the form of a flexible, substantially inextensible, belt guided to follow a closed path, an image forming station for forming an ink image, a drying station for drying the ink image to leave an ink residue film, first and second impression stations spaced from one another in the direction of movement of the belt, each impression station comprising an impression cylinder for supporting and transporting a substrate and a pressure cylinder for urging the belt against the substrate supported on the impression cylinder, and a transport system including a perfecting system for selectively inverting the substrate during transportation between the two impression stations; and a treatment station situated between the second impression station and the image forming station, the treatment station configured to apply a treatment agent comprising polyethylenimine (PEI) to pre-treat the belt.

A printing system for printing on a substrate. In embodiments, the system comprises: a movable intermediate transfer member in the form of a flexible, substantially inextensible, thin belt whose compressible layer has a thickness of at most 400 micrometers, the belt being guided to follow a closed path, an image forming station for depositing ink droplets onto an outer surface of the belt to form an ink image, a drying station for drying the ink image to leave an ink residue film, first and second impression stations spaced from one another in the direction of movement of the belt, each impression station comprising an impression cylinder for supporting and transporting the substrate and a pressure cylinder carrying a thick compressible blanket for urging the belt against the substrate supported on the impression cylinder, a thickness of the compressible blanket being at least 1 mm.

A system for preparing a flexographic printing plate having a printing layer, a second layer, and a cushion layer includes a first laser for imaging a first zone on a bottom surface of the cushion layer; and wherein the first laser or a second laser images a first area of a top surface of the printing layer which corresponds to the first zone.

Integral cushion for flexographic printing plates

An imaging system () includes an imaging lens () prone to temperature changes which leads to changes in the imaging focus position of the imaging lens. A temperature sensor () configured to monitor the temperature of the imaging lens. An imaging lens adjustment element () attached to the imaging lens configured to adjust the setting of the imaging lens. A controller () configured to process temperature readings and adjust the position of the imaging lens by activating the imaging lens adjustment element.

Apparatus for compensating an imaging lens

An automatic plate feeding system for loading plates of various sizes into a printing plate imaging device, which includes a plurality of trays staggered one on top of the other is provided. At least two of the trays contain plates of different sizes stacked with their sensitive side downward. Separation papers are interposed between the plates. The automatic plate feeding system includes suction cups, which touch the non-sensitive surface of the plate, and a loading mechanism for loading plates from the trays and feeding the loaded plates to the imaging device.

Automatic printing plate feeding system

A system for loading and clamping one or more plates onto the cylindrical surface of a rotatable drum, such as used in a platesetter for printing, and for unloading the plates from the drum. The system is characterized by clamps that are movable over the surface, preferably along circumferential tracks, enabling the attachment of multiple plates, end-to-end and/or side-by-side, each plate having any of a wide range of sizes. The clamps are preferably of the dynamic type, whereby the clamping force increases with rotational speed. Also disclosed is a method for mounting and unmounting plates, using the movable clamps, such that allows flexible and convenient arrangement of loading- and unloading stations.

An automatic plate feeding system for loading plates of various sizes into a printing plate imaging device, which includes a plurality of trays staggered one on top of the other, and an arm mechanism for loading plates from the plurality of trays and feeding the loaded plates to the imaging device.

Automatic plate feeding system

Disclosed are apparatus and methods for protecting an optical system from residual material that is scattered and dispersed during the imaging of printing plates and collecting same. The apparatus includes a housing with upper and lower chambers and surrounding at least a portion of the printing drum. The lower chamber is configured to be fitted to the optical system of the imager. A compressed air supply connects to the lower chamber and a suction device connects to the upper chamber for extracting the residual material. Air from the compressed air supply is moved through the lower chamber forming two air-streams, which are drawn into the upper chamber with the residual material of the imaging process.

Apparatus for loading and unloading plates to external drum devices having movable clamps

A clamp for gripping an edge of a plate that is mounted on the surface of a rotatable drum. The clamp includes a hinge, attached to the drum and including a pivot axis, and a gripper, formed to have a tip, operative to press the edge of the plate against the drum. The gripper is attached to the hinge so that the center of mass of the gripper is in a direction from the pivot axis that is generally opposite the direction of the tip from the pivot axis.
