Document Type and Number:
WIPO Patent Application WO/2023/182436
Kind Code:
A1
Abstract:
Provided is an inkjet recording method comprising a step for circulating ink and discharging the ink from an inkjet head so as to provide the ink onto a recording medium, wherein: in the ink, the number of white large particles, which are white pigment having a particle size in the range of 0.8-5 μm, is not less than 1.00×104 particles / cm3; a circulation flow path includes a circulation tube which returns the ink to the inkjet head; and the below speed ratio (1) is 5.0×103 to 1.4×105. Vc is the circulation flow speed (cm/s) of the ink in a part of the circulation tube connected to the inkjet head. Vslp is the settling speed (cm/s) of the white large particles as defined by a prescribed formula. Pn is the number of white large particles (particles/cm3). Speed ratio (1) = Vc/(Vslp×log(Pn))
