Print enhancement of pixels to improve readability

摘要

A method to improve the image of a printed barcode (60) by enhancing coverage of the print pixels within solid printed areas to improve the print uniformity and decrease the graininess of the typical ink jet printing by dissolving a small percentage of the colorant and distributing more uniformly. The parameter improved by the invention is the graininess or uniformity of coverage. The contrast ratio within barcode data elements (64) can be also improved without causing unwanted image bleed into unintended areas. Hence, the printed barcode (60) will contain more clearly defined printed (64) and non printed (65) areas to enable the barcode (60) to be accurately read. The invention prevents also unwanted bleeding in areas where it could lower the quality of the printed material by avoiding application of enhanced coverage facilitators when desired white space is identified within a minimum distance.
