Generation Copy Mode

Generation Copy, based mainly on text mode, aims to achieve the best

reproduction of copied originals (so called "generation copies" or copies of copies).

This mode employs an MTF filter weaker than that of the text mode to eliminate

spurious dots, uses the γ coefficient to smooth the image, and uses generation

processing to thicken thin lines. Soft employs an MTF filter weaker than the Normal

setting to achieve a softer image with less moiré. Sharp employs an MTF filter

stronger than that for Normal to emphasize lines for better image quality.
