An image processing device and image processing method maintain hue and prevent a drop in print quality while also reducing consumption of recording materials. For example, a host computer 3 that outputs output data for printing to a inkjet printer 2 that uses cyan (C), magenta (M), and yellow (Y) inks has a drawing unit 210 that acquires bitmap data expressing the density of each channel in each pixel of an image to be printed, a density adjustment parameter setting unit 250 that sets an adjustment value according to the ink deposition level when the ink deposition level setting ink usage is received, a density adjustment unit 220 that adjusts the density of the bitmap data to a density corresponding to the set adjustment value, a color conversion unit 230 that converts the density-adjusted bitmap data to CMY image data expressing the usage of each ink, and a halftone processing unit 240 that generates the output data based on the CMY image data.
