发明名称 Interlaced ink jet printing
摘要 A pixel row interlacing method and system, and print head for practicing same, for use with dot-matrix ink jet printers which apply ink to a substrate as elevated temperatures (e.g., phase change ink jet printers), which assures environmentally symmetric ordered placement of molten ink droplets and, thereby, achieves seamless dot-matrix printing and minimizes the horizontal striping or "banding" effects which are prevalent in prior art printers. Odd rows of print region are printed in one pass and the even rows of the same region are printed in the following pass. The guidelines for laying down dots are essentially: (1) adjacent dot rows should not be laid down in the same pass; (2) each dot row should be sandwiched by either (a) virgin paper on both sides of the dot row, or (b) ink on both sides of the dot row; (3) the first and the last dot row in each solid pattern are exempted from guidelines #2 and #3.
