A printing system comprises an intermediate transfer member, an image-forming station comprising a print bar disposed over a surface of the ITM, a conveyer for driving rotation of the ITM, a detection system configured to detect foreign matter transported at a detection location upstream of the image-forming station, and a response system operatively coupled to the detection system to respond to the detection of foreign matter by performing at least one collision-prevention action to prevent a potential collision between foreign matter and the print bar.

Protection of components of digital printing systems

Some embodiments relate to printing system is described that has an intermediate transfer member (ITM) in the form of a seamed endless belt for transporting an ink image from an image forming station, at which an ink image is deposited on ITM, to an impression station, where the ink image is transferred onto a printing substrate. Two drive members are provided for movement in synchronism with one another. Rotation of the drive members during installation of a new ITM serves to thread the strip through the printing system by pulling the strip from its leading end. Alternatively or additionally, indirect printing system comprising the ITM and an image forming station at which droplets of ink are applied to the ITM to form ink images thereon is disclosed. One or more blowing mechanisms (e.g. associated with the image forming station) are disclosed herein.

Indirect printing system and related apparatus

A method of printing includes, applying to an intermediate transfer member (ITM) (), one or more fluids that include at least a printing fluid for forming an image on the ITM (). At least part of the image is transferred from the ITM () to a target substrate (). Residues of the one or more fluids that were not transferred to the target substrate () and remained on the ITM (), are transferred from the ITM () to one or more rotatable elements (), and the residues are removed from the one or more rotatable elements ().

Printing method and system

A digital printing system () includes a flexible intermediate transfer member (ITM) () and a dancer assembly (). The ITM () is configured to receive ink droplets from an ink supply system to form an image thereon, and to transfer the image to a target substrate (). The dancer assembly () includes a fluid chamber () and a rotatable element () fitted in the fluid chamber (), the fluid chamber () includes an inlet () configured to receive pressurized fluid () into the fluid chamber (), and the pressurized fluid () causes the rotatable element () to move relative to the fluid chamber () and to apply tension to the ITM () while being rotated by the ITM ().

Apparatus for controlling tension applied to a flexible member

A friction reduction system for reducing friction of an intermediate transfer member (ITM) of a printing system, while the ITM is guided along the printing system by a guiding arrangement. The friction reduction system includes a fluid reservoir mounted within the printing system, a fluid depositing arrangement disposed along the ITM, and a control mechanism, adapted to control depositing of fluid, from the fluid depositing arrangement onto the guiding arrangement or onto at least a portion of the ITM. Depositing of the fluid reduces friction between the ITM and the guiding arrangement.

Friction reduction system and method

Friction reduction means for printing systems and method

A printing system comprises an intermediate transfer member, an image-forming station comprising a print bar disposed over a surface of the ITM, a conveyer for driving rotation of the ITM, a detection system configured to detect foreign mattertransported at a detection location upstream of the image-forming station, and a response system operatively coupled to the detection system to respond to the detection of foreign matter by performing at least one collision-prevention action to prevent a potential collision between foreign matter and the print bar.

A printing system is described that has an intermediate transfer member in the form of a seamed endless belt for transporting an ink image from an image forming station, at which an ink image is deposited on the intermediate transfer member, to an impression station, where the ink image is transferred onto a printing substrate. The belt has along its edges formations of a greater thickness than the belt. The formations are received in channels to guide the belt and maintain the belt under lateral tension. Two drive members are provided, each located within a respective one of the channels. The two drive members are connected for movement in synchronism with one another and each has a respective laterally projecting gripper shaped for form locking engagement with the formations on a leading end of a strip from which the intermediate transfer member is to be formed. Rotation of the drive members during installation of a new intermediate transfer member serves to thread the strip through the printing system by pulling the strip from its leading end.

Apparatus for threading an intermediate transfer member of a printing system

The present invention provides a printing assembly which includes a printing drum such as an impression drum, a pair of eccentric bearings between and on which the drum is mounted for rotation, a pair of self aligning bearings on which the eccentric bearings are supported, and a pair of frameless motors directly connected to the eccentric bearings in order to effect the rotation thereof through closed loop feedback control, in order to facilitate the automatic and accurate control of pressure level and uniformity along the nip of a printing press.
