  • PRINT SMOOTHING METHOD
    Publication number: 20100045721
    Abstract: In dot matrix printing and use with a dot matrix printer, a first swath of ink dots is laid down during a first pass of a printing head. The first swath comprises a first zone (9) and a second zone (7, 8), extending along the entire length of the swath. The second zone extends from the first zone to an outer longitudinal border of the swath; which is not a straight line. The average concentration of ink dots in the second zone is arranged to be lower than the average concentration (1) of ink dots in the first zone. One or more additional swaths of ink dots are laid down during following passes of the printing head, which overlap the second zone of the first swath, thereby increasing the average concentration of ink dots in the second zone for obtaining a substantially equal concentration of ink dots in the first and second zones.
