An ink agitating apparatus comprises a generally rectangular curved blade (16) having concave recesses (28a, 28b, 30) in its side and bottom edges. The blade (16) is adapted to be reciprocated laterally by a pneumatic mechanism (20). The blade is flexible so that it can be twisted longitudinally by the hydrodynamic forces to which it is subjected when it moves through the ink whereby to improve the agitation characteristic achieved by the blade. <IMAGE>
