Sharpness
Adjusts the sharpness of image outlines.
When copying penciled originals with rough or broken lines, clear copies can be taken by adjusting sharpness toward
"Sharpen". When copying images made up of patterned dots such as magazine photos, in which moire* patterns
appear, edge softening and weakening of the moire effect can be obtained by setting the sharpness toward "Blur".
When [All] is selected, press [-3] to [3] (Blur - Sharpen) to adjust the sharpness.
When [Text/Fine Line] is selected, press [0] to [3] (Normal - Sharpen) to adjust the sharpness.
* Patterns that are created by irregular distribution of halftone dots.

density of the ground color.
