ABSTRACT:
A color ink ribbon comprising a ribbon body on which a plurality of colors are sequentially aligned in a ribbon feeding direction, color recognition marks which sequentially represent next colors on the ribbon body by bar code information, and ribbon speed detection marks formed on the ribbon body at equal intervals in the ribbon feeding direction. The bar code marks and the speed detections marks are used together with a compensation coefficient to determine the identity of the subsequent color portion on the ink ribbon body.
