摘要： An ink jet recording method is provided for a low or non-absorbable recording medium using a solution containing a colored ink, a clear ink, and an aggregating agent for aggregating constituents in the colored ink. The method includes: causing the solution containing the aggregating agent to adhere to the recording medium; and a main scanning in which the colored and the clear inks are ejected while relative positions of an ink jet head and the recording medium are changed to a main scanning direction, and a sub-scanning in which the relative positions of the ink jet head and the recording medium are changed to a sub-scanning direction. The main scanning involves a region where a recording region in which the colored ink is ejected in the main scanning and a recording region in which the clear ink is ejected in the main scanning overlap one another.

摘要： An ink jet recording method is provided for recording white and non-white ink compositions onto a moving recording medium. The recording medium includes a first region where both the white and non-white ink compositions are adhered, and a second region where only the white ink composition is adhered. Further, one or both of Conditions (i) and (ii) is satisfied. Condition (i): The amount of the white ink composition adhered in the first region is less than the amount of the white ink composition adhered in the second region. Condition (ii): The number of times the white ink composition is scanned across the first region is less than the number of times the white ink composition is scanned across in the second region.
