Claim:
A print management system comprising an issue server, an acceptance server and a client terminal and managing the printing of sheets, wherein said issue server includes: a parameter table which stores a plurality of sets of parameters where, one set of parameters is made up of a plurality of ink mixing ratios for filling out a filling pattern; means which fills out a filling pattern in accordance with the ink mixing ratios stored as said one set of parameters; and printing test data generating means which generates the printing test data with said filling pattern, wherein the areas filled with said one set of parameters have different optical properties, wherein said printing test data use said filling patterns generated according to said different parameters, as a background and an image respectively, wherein said client terminal includes: printing means which prints said printing test data; and transmitting means which accepts self-report data by a user of said client terminal, on whether or not said image and said background printed can be discriminated, and transmits the self-report data to said acceptance server, and wherein said acceptance server includes: specifying means which specifies at least one set of parameters containing the ink mixing ratios creating the user-undiscriminating colors in the case of printing at said client terminal; and requesting means which requests said issue server for generating the print data to print said sheets with said specified parameters.
