An inkjet recording device having droplet ejection heads that respectively eject ink liquids of plural colors and a reaction liquid at a recording medium; a preparation section, that prepares dot data representing ejection-amounts of the ink liquids and the reaction liquid for each dot, based on gradation values of each pixel of an image represented by image data, such that ejection-amounts of the ink liquids of some colors, each having high in visibility, are represented by data with a predetermined number of bits, and ejection-amounts of the reaction liquid and the ink liquid of the rest color are represented by data with a number of bits smaller than the predetermined number, and a number of bits of the dot data for one dot is an integer multiple of eight bits; and a control section that controls ejection based on the prepared dot data, is provided.
