Indirect inkjet printing system

An indirect printing system comprising:

• a. an intermediate transfer member (ITM);
• b. an image forming station at which droplets of ink are applied to an outer surface of said ITM to form ink images thereon, the image forming station including:
• a first print bar including a first plurality of print heads spaced from said ITM by a first gap and having mounted thereon a first blowing mechanism, configured for blowing a first gas flow into said first gap in a print direction, said first gas flow having a first flow rate;
• and
• a second print bar including a second plurality of print heads spaced from said ITM by a second gap and having mounted thereon a second blowing mechanism, configured for blowing a second gas flow into said second gap in said print direction, said second gas flow having a second flow rate, said second print bar being disposed downstream of said first print bar;
• c. an impression station for transfer of the ink images from said ITM onto a printing substrate;
• and
• d. a guiding system for guiding said ITM along said image forming station, and from said image forming station to said impression station,
• wherein (i) said second flow rate is different from said first slow rate;
• (ii) each of said first and second blowing mechanism includes a main body defining a first chamber and a first gas flow outlet in fluid connection with said first chamber, said first chamber including at least two compartment connected by at least one slot, and at least one perforated baffle plate, such that gas flow exiting said first gas flow outlet has an even pressure along a length of a corresponding said blowing mechanism;
• and
• (iii) said main body of each of said first and second blowing mechanisms includes a second chamber fluidly connected to a third chamber and a second gas flow outlet in fluid communication with said third chamber, the second chamber, third chamber and second gas flow outlet form a second flow path separate from a flow path formed by said first chamber and said first gas flow outlet.
