Abstract
An ink supply system for an industrial inkjet printer makes use of a least one buffer vessel wherein ink at low pressure is isolated and pressurized to a high pressure suited for feeding the ink to the printhead. A recirculation ink supply system using plural buffer vessels is suited for repressurizing the ink without the use of a pump. The system avoids generation of gas bubbles due to cavitation which are present in systems using a pump for repressurizing ink.
