It is a deterministic transformation of pixels to printer dots. I specifically call this "invented". There is no capture pixel duplicated precisely in the output dot. The dots would get huge quickly, which would give blocky hard copy outputs. The output dot is made to approximate the input pixel using multiple dots of ink, determioned by the driver. In that deterministic algorithm, the decision is made to enhance the edges of the dot, add pigment to the center of the pixel, change color to the surrounding dots, subtract density to the edges, use 4 color to approximate one color, etc. I can clearly see the difference in what this driver does and a 1:1 pixel by pixel representation to the output of the input data. "...Film grains are very random in shape and size. Pixels represent a perfect square section of an image and do not vary in shape and size...." The point is that wet or digital film both use pixels. If you wish to compare technologies and capabilities, then you must compare similar concepts, taking into account the differences. It is too easy to incorrectly state wet film has no pixels, and therefore there is no comparison or similar standard to digital capture pixels which are more easily understood as electronic individual image sensor points. ( I am not accusing you of doing this, but the general Marketing Hype in this area surely does.) Frank
