Abstract: The present invention relates to an ink circulation supply system for an inkjet head. The system is configured to supply ink to the inkjet head having a plurality of nozzles for ejecting the ink, and includes: a meniscus reservoir; a circulation reservoir; and an ante reservoir, the reservoirs where a first pressure connection pipe with a first pressure valve, a second pressure connection pipe with a second pressure valve, a first ink connection pipe, and a second ink connection pipe with an ink valve are provided, wherein when the internal pressure of the circulation reservoir is controlled to be lower than that of the meniscus reservoir, the ink stored in the meniscus reservoir is moved to the circulation reservoir without requiring use of a separate pump.
