1. A printing system comprising:
a. an intermediate transfer member (ITM) comprising a flexible belt operable to have ink images formed thereupon by droplet deposition at an image-forming station; and
b. an impression station configured for transfer of the ink image to substrate after they are conveyed to the impression station by the ITM, the impression station comprising:
i. a rotatable impression cylinder having a cylinder gap that houses a plurality of grippers spaced along a gripper shaft so as to define a plurality of inter-gripper regions, each gripper of the plurality of grippers being disposed in the cylinder gap of the impression cylinder;
ii. a jacket disposed around a portion of the circumference of the impression cylinder, the jacket comprising multiple tab portions; and
iii. a jacket-securing arrangement for securing a tab portion of the jacket to the rotatable impression cylinder, the jacket-securing arrangement comprising:
a. a magnet;
b. a first member, configured for holding the magnet; and
c. a second member, detachably attachable to the first member, the first and the second members being adapted to be rotatably mounted around the gripper shaft when disposed in an assembled state in one of the inter-gripper regions,
wherein when in said assembled state, the jacket-securing arrangement is configured to magnetically secure the jacket tab portion to the impression cylinder when in a first rotated position and not to magnetically secure the jacket tab portion to the impression cylinder when in a second rotated position, and
wherein a plurality of the jacket-securing arrangements is arranged to secure a corresponding plurality of the jacket tab portions to a surface of the cylinder gap, said plurality of jacket-securing arrangements being disposed in said respective assembled states within the cylinder gap such that each jacket-securing arrangement of the plurality of jacket-securing arrangements is disposed in a respective inter-gripper region.
