METHOD FOR INKJET RECORDING AND DEVICE FOR INKJET RECORDING Russian patent published in 2017 - IPC B41J2/15 

FIELD: printing industry.

SUBSTANCE: inkjet recording method implemented by an inkjet recording device including a nozzle plate with a nozzle for ink droplets discharge; a recording head including a liquid chamber to which the nozzle is connected and a pressure generation unit configured to generate pressure in the liquid chamber; and a signal generation unit configured to generate a signal applied to the pressure generation assembly and making it possible to discharge the ink droplets under the pressure generated by the pressure generation unit in accordance with the, signal where ink has a static surface tension of 18.0 mN/m to 27.0 mN/m at 25°C, ink has a retracting contact angle on the nozzle plate of 50° or more, the signal has a two-stage traction pulse to draw the ink into the nozzle in a two-step manner within one single cycle and the method includes drawing of ink located near the nozzle outlet into the nozzle under the action of the two-step traction pulse to form a meniscus at a predetermined location.

EFFECT: provision of an inkjet recording method that makes it possible to produce a stable output of ink having a low static surface tension and a large retracting contact angle, and which provides a high quality image.
