A color conversion table creation device includes an image reading unit, a first color conversion unit color-converting read image data using a first color conversion table indicating a correspondence relationship between signal values obtained by the image reading unit and chromaticity values, a second color conversion unit color-converting document image data into print image data using an input and output color conversion tables, an image association unit performing an association process for a positional relationship between each piece of read image data of a printed matter obtained according to print image data and a target printed matter or each piece of read chromaticity value image data converted into chromaticity values and the document image data, and a color conversion table creation unit creating a color conversion table to be used in the second color conversion table based on differences between chromaticity values of the target printed matter and printed matter.
