An ink reservoir (10), for supplying ink to at least one inkjet print head (32a, 32e), containing partitions (19) which divide the volume of ink in the reservoir (10) into sub-volumes, which significantly reduce, or eliminate, pressure fluctuations which arise as a result of acceleration of the ink reservoir (10). Each sub-volume is connected to adjacent sub-volumes by means of pressure equilibration passages. Lower pressure equilibration passages ensure equal ink height within all sub-volumes, following passages ensure equal air pressure above all sub-volumes. A further aspect involves a reservoir supplying print heads (32a, 32e) where planes, substantially perpendicular to the primary direction of motion, intersect corresponding reservoir supply outlets (13a, 13e) and print head supply inlets (35a, 35e) in order to eliminate supply line pressure fluctuations. A combination of the two aspects eliminate both reservoir and supply line pressure fluctuations.
