Abstract: Reaction liquid application S1 to an ink receiving medium, formation of a first image by ink application S2, liquid absorption S3 from the first image by a porous body of a liquid absorbing member, cleaning S4 of the porous body, and liquid collection S5 from the porous body are repeated in an inkjet printing method. When the porous body comes into contact with the first image, first chemical species in the reaction liquid contributing to increasing the ink viscosity is contained, on the ink receiving medium and in the porous body, at a higher level in terms of molar equivalent per unit area than second chemical species in the ink also contributing to increasing the ink viscosity. In the liquid collection S5, the liquid is collected so that the liquid remains in the porous body on the side to be brought into contact with the first image.

Abstract: A gas discharge hole 74 (205) configured to discharge a gas is provided at a position outside an edge of a substrate W held by a substrate holding unit 89 (204) within a processing chamber 81 (201).

Abstract: In image processing, for a pixel with a density level smaller than a predetermined threshold value, the density level is corrected based on a parameter representing a degree of condensation of ink in a nozzle. For pixel with a density level equal to or larger than the predetermined threshold value, the density level is not corrected. This makes it possible to suppress an unevenness in density caused by the condensation of ink while suppressing blur at a contour of a character or a thin line.
