Zusammenfassung:	An ink pressure regulator for use inside of a flexible ink bag reservoir for a replaceable or refillable ink cartridge comprises a bow spring (60) configured to have substantially linear force/deflection characteristics and a pair of plates (40, 50) which collapse to a substantially flat shape to minimize the amount of ink remaining after printing has depleted the ink from the cartridge. The regulator may be manufactured of one or a plurality of separate pieces.
