Method and apparatus for stitching print swaths in an image-rendering device |
摘要 |
This invention relates to a method and apparatus for stitching print swaths in an image-rendering device such as an acoustic ink printer. More particularly, the invention is directed to a method implemented in an apparatus to reduce the visual artifact caused by inaccurate paper advance between neighboring swaths of an ink emitter printhead. The method includes the provision of a "puzzle cut" or "zipper" edge between swaths. In this regard, the image is divided into swaths and the edges thereof are dithered to vary the depth of the cut in accordance with the expected paper advance accuracy and other printing characteristics such as noise and variations in the width of print swaths for different printheads.
