ABSTRACT:
A printer and a method for printing is described in which bleed between secondary color regions having different colors is minimized by the formation of a border strip which has a color which is common to both secondary color regions. In a printer assembly which includes a print head for depositing ink onto a media, an improved image may be formed by processing the data before the image is printed such that a border strip is formed between adjoining regions of different secondary colors. The border strip is printed in a color which is common to both of the secondary color regions. Thus, because the color which is common to both secondary color regions is printed in the border region, the contrast between the three areas of different colors is minimized. In addition, the reduced volume of ink within the border strip further minimized ink bleed. Thus, a border strip which is significantly less visible to the naked eye, is formed which minimizes bleed between the two secondary color regions.
