ABSTRACT:
A color ink ribbon in which one half of the width of the ribbon is utilized for the left-to-right (first) printing direction and the other half of the width is utilized for the right-to-left (second) printing direction, and in which the sequence of ink layers composed of at least three colors is the same for both printing directions, whereby the ribbon can be used for printing in both the forward and reverse directions without wasteful non-utilization of areas in either half of the ribbon.
