ABSTRACT:
The horizontal resolution of an input dot image is multiplied by an odd integer m, greater than unity, to produce an intermediate image. The intermediate image is smoothed by logic operations to form a final image, which is printed at a horizontal resolution equal to the horizontal resolution of the intermediate image divided by two. The horizontal resolution of the input dot image is therefore multiplied by a half-integer value (m/2) in the final image. The vertical resolution of the final image is twice the vertical resolution of the intermediate image, but may be adjusted by reducing the space between raster lines if necessary, so that the image can be printed on one page.
