SM
Pale (Low-Density Mode)
Pale achieves image quality comparable with Text mode, but of lower contrast.
Pale employs an MTF filter stronger than that employed by the Text mode and
uses a darker
γ
coefficient, thus increasing the incidence of copying textured
backgrounds. Ideal for copying extremely thin originals. Soft employs an MTF filter
weaker than Normal, thus achieving a softer image with less moiré. Sharp employs
an MTF filter stronger than that of Normal, thus increasing the sharpness of lines.
