Abstract
There is provided a patch measurement device which, even if the position of a patch in a control strip printed on a printed material is incorrectly detected, does not affect the controlling of the printing apparatus. A data storage sectionin a patch measurement devicestores printed-image data Dpd. A reference mark detection sectiondetects a reference mark rm in the printed-image data Dpd, and generates position data thereof. A reference mark position data comparison sectioncompares the position data against past position data stored in a reference mark position data storage sectionto determine the validity of the position data. If the position data is valid, a patch position detection sectiondetects a patch whose color density is to be measured. A color density measurement sectiongenerates color density measurement data of the printed patch. A color density calculation sectioncalculates color density information Dct by using current and past color density measurement data stored in a color density measurement data storage section
