ABSTRACT:
A method for printing a postal indicia includes printing a first dot-matrix ink pattern of the postal indicia; and printing a second dot-matrix ink pattern of a portion of the postal indicia in overlapping relationship to the first dot-matrix ink pattern such that a combination of the first and second dot-matrix ink patterns results in a combined dot-matrix pattern of the postal indicia having a first dot density along its length and a second dot density along its height, the first and second dot densities being different from each other but sufficient in combination to permit detection of the combined dot-matrix ink pattern by a facer/canceler machine. An apparatus incorporates the above method.
