Claim 12:
13. A printing system comprising:
a. an intermediate transfer member (ITM) comprising a flexible endless belt;
b. an image-forming station configured to form ink images by droplet deposition upon a surface of the ITM moving through the image forming station;
c. an impression station where the ink images are transferred to substrate from the ITM surface;
d. a conveyer for driving rotation of the ITM to transport the ink images towards the impression station;
e. a treatment station disposed downstream of the impression station and upstream of the image-forming station configured for coating the ITM surface with a layer of a liquid treatment formulation, the treatment station comprising:
i. an applicator for applying the liquid treatment formulation to the ITM;
ii. a coating thickness-regulation assembly comprising a plurality of blades, the assembly configured so that for at least a part of the time each one of the blades is in an active position, so as to leave only the desired layer of treatment formulation on the surface of the ITM as it traverses the blade in the active position;
iii. a blade-replacement mechanism, associated with the coating thickness-regulation assembly and configured for performing blade-replacement operations to replace a blade in the active position with another blade, wherein a blade-replacement operation causes a local stretching of the ITM proximate to the portion of the ITM passing a blade in the active position; and

f. a controller configured to detect said local stretching of the ITM and respond by modulating a timing of the droplet deposition so as to compensate for said local stretching of the ITM.
