1. A managing device for managing a result of image capturing by an image capturing device of a pattern, provided onto a printed material, from which information on control of a print process on a print processing device is identified, the managing device comprising: obtaining means for obtaining, from a storage device, reference pattern data which provides a reference in identifying the pattern and output pattern data used to print the pattern; determining means for determining a matching level between the reference pattern data and the result of image capturing, the result of image capturing being produced by the image capturing device of the pattern printed based on the output pattern data; and modifying means for modifying output pattern data corresponding to a captured pattern if the determining means determines that the matching level is less than a predetermined threshold.
