PROBLEM TO BE SOLVED: To provide a printing device capable of automatically controlling the feed amount of ink without the necessity to prepare a printed matter as a reference. SOLUTION: Image data d1 for controlling the feed amount of ink is received from an external image data creating means. A standard color data arithmetic means 41 obtains standard color data da by converting values in the L*a*b* color specification series through matching with the region of each of ink keys of the ink feed means. A print color data arithmetic means 43 processes image data d2 which are obtained by reading an actually printed image by an image photographing means using the same technique as used in the processing of the standard color data da to obtain print color data db. A differential data arithmetic means 44 processes differential data dc by comparing the standard color data da with the print color data db per ink key region. A correction data arithmetic means 45 seeks correction data d3, per color, which indicates a correction quantity for the opening of the ink key 31 corresponding to a density value from the differential data dc. A control part adjusts the opening of each of the ink keys 31 of the ink feed means based on the correction data d3. |
