Neighbor insentive pixel deletion method for printing high resolution image

摘要

To print an image having a 600 dpi resolution along the horizontal axis with an ink jet printer that has a 300 dpi resolution, the method maintains the edges of the pixel image and uses a checkerboard pattern for all interior pixels other than the second pixel and the second last pixel of each pixel row. Therefore, the method is neighbor insensitive by using a checkerboard pattern or mask to determine the state of the interior pixels. After turning OFF the respective pixels, ink drops are fired from the ink jet printer at areas corresponding to the remaining ON pixels. This visibly reproduces the image at the 600 dpi resolution.
