    • A method to improve the image of a printed barcode 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 can be also improved without causing unwanted image bleed into unintended areas. Hence, the printed barcode will contain more clearly defined printed and non printed areas to enable the barcode 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.
    • 通过提高固体印刷区域内的印刷像素的覆盖度来改善打印条形码的图像的方法,以通过溶解少量的着色剂并更均匀地分布来改善印刷均匀性并降低典型喷墨印刷的颗粒度。 本发明改进的参数是颗粒度或覆盖均匀性。 还可以改善条形码数据元素内的对比度,而不会造成不需要的图像渗透到非预期的区域。 因此,打印的条形码将包含更清晰定义的打印区域和非打印区域,以便能够准确地读取条形码。 本发明在通过避免在最小距离内识别出希望的空白空间的情况下避免使用增强的覆盖促进器的区域中也可以防止在可能降低打印材料质量的区域中的不期望的渗色。
