Digital printing system with flexible intermediate transfer member

A printing system comprising:

• a. an image-forming station at which ink images are formed by droplet deposition on a rotating flexible intermediate transfer member (ITM);
• b. electronic circuitry configured to track a first ITM stretch factor at the image-forming station and a second ITM stretch factor at an impression station downstream of the image-forming station at which the ink images are transferred to substrate, and to control deposition of droplets onto the ITM at the imaging station so as to modify a spacing between ink droplets in accordance with the first ITM stretch factor;
• and
• c. the impression station, at which the ink images are transferred to substrate with a spacing between ink droplets in accordance with the second stretch factor.

A printing system comprising:

• a. an intermediate transfer member (ITM) comprising a flexible endless belt mounted over a plurality of guide rollers and rotating in a print direction;
• b. an image-forming station comprising a print bar disposed over a surface of the ITM, the print bar configured to deposit droplets upon a surface of the ITM so as to form ink images characterized at least in part by a first between-droplet spacing in the print direction which is selected in accordance with in accordance with data associated with stretching of the ITM at the print bar;
• and
• c. a conveyer for driving rotation of the ITM in a print direction to transport the ink images towards an impression station where they are transferred to substrate with a second between-droplet spacing in the print direction, wherein the second between-droplet spacing is smaller than the first between-droplet spacing and wherein the first between-droplet spacing in the print direction is further selected in accordance with a sub-unity ratio between:
• (i) the second between-droplet spacing, and
• (ii) the first between-droplet spacing,
• said sub-unity ratio describing an extent-of-decrease of local-ITM stretch between the image-forming and impression stations.
