ABSTRACT:
The inventive method reduces the quantity of the actual number of pixels to be printed to attain a given resolution, on average, by half, with each two or pair of adjacent pixels of the original print information being sequentially processed to form a print pixel and a socalled white or unprinted pixel. The arrangement of print pixels and white pixels is effected so as to print a checkerboard pattern. The ink droplets accordingly have the smallest possible substrate or print media contact area so that adjacent ink droplets which are not yet dry are effectively prevented from running together and thereby degrading the resulting image.
