The invention relates to an adjusting mechanism for zonal control of an ink blade (2) in respect of a ductor roller surface (5) in a printing press. The adjusting mechanism comprising a plurality of moving means (1) in contact with the ink blade and movable in a longitudinal direction (P1, P2) towards and away from said ductor roller. Each moving mean comprises at least one bar (6) of a shape memory material (SMM) and activating means (7) to provide e.g. a magnetic field strength (H±DELTAH) bar(s). A controlled electrical voltage/current (U, I) is fed into the activating means, whereupon a variable length (L±DELTAL) of said bar is determined for said adjustment.
