ABSTRACT:
A color ink ribbon has a plurality of color areas and a plurality of black areas alternatively arranged on the ribbon in longitudinal direction thereof and each having a length greater than the width of the ribbon. The color areas are each subdivided in width into a plurality of strip-like areas each being impregnated with or coated with ink of particular color, i.e., yellow, magenta or cyan. The black areas are each impregnated with or coated with black ink over the entire width thereof. A color printer using the ribbon has a print head provided with heating elements which are arranged on an area corresponding to the entire width of the ribbon. The black areas of the ribbon are provided with a greater width than the color areas, so that black image data may be printed out continuously or on a plurality of lines at a time without the ribbon being fed.
