Abstract:
An inkjet recording device including: inkjet head having a pressure chamber; a first pressure source to adjust ink energy per unit volume to generate “energy per unit volume” P1(Pa) relative to static ink at an atmospheric pressure at a nozzle opening height; a second pressure source to adjust ink energy per unit volume to generate “energy per unit volume” P2(Pa) relative to static ink; and a hardware processor. The first pressure source, pressure chamber, and second pressure source are connected in this order by a flow path. Assuming that a pressure loss occurring from the first pressure source to the nozzle due to circulation flow rate is ΔPa, a proportionality constant of a differential pressure (P1−P2) and ΔPa is “a”, and an appropriate pressure in vicinity of the nozzle opening is Pn, the hardware processor controls pressure to establish P2={Pn−(1−a)P1}/a.
