Abstract (en)

Rather than transporting the entire multi-colour print ribbon (18) in an impact printer back and forth until the reaching of a lower quality threshold requires replacement, this method provides for the use of only a subsection of limited length of the ribbon to be used until the lower quality threshold of any one of the colour tracks (21-24) of this subsection is reached, and then advancing to a fresh subsection. The quality status of the current subsection may be monitored by counting the number of impacts on each individual colour track and comparing that number with a predetermined, stored value, or by shining light through the ribbon and optically comparing the passing light with a preset value. The method is flexible enough to permit manual advance of the ribbon (18) to a fresh subsection in case a printing job requires highest possible quality.
