Abstract: The present invention relates to a device and a method for evaluating the quality of a printed image. The device for evaluating the quality of a printed image according to the present invention includes: a binary coding unit converting an evaluation image having a dot area into a binary coded image; a grid extracting unit extracting a grid for separating the dot areas from the binary coded image converted in the binary coding unit; and an image evaluation unit evaluating the binary coded image using the dot area in each grid. Therefore, the concentration of a printed image can be evaluated. [Reference numerals] (110) Evaluation image input unit; (120) Binary coding unit;; (130) Dot area center extracting unit; (140) Grid extracting unit; (150) Valid area selection unit; (160) Image evaluation unit
