This abstract first appeared for US patent application 18888432 titled 'INKJET RECORDING METHOD

Original Abstract Submitted

Provided is an ink jet recording method including a step of circulating an ink and jetting the ink from an ink jet head to apply the ink onto a recording medium, in which the number of white large particles as a white pigment having a particle diameter in a range of 0.8 μm to 5 μm in the ink is 1.00×10pieces/cmor greater, the circulation flow passage includes a circulation tube for returning the ink to the ink jet head, and a velocity ratio (1) described below is 5.0×10or greater and 1.4×10or less. Vc represents a circulation flow rate (cm/s) of the ink in a connecting portion between the circulation tube and the ink jet head, Vslp represents a sedimentation velocity (cm/s) of the white large particles, which is defined by a predetermined equation, and Pn represents the number of the white large particles (pieces/cm).
