8 - 6
This filter typically provides better JPEG compression than the standard E -
Edge Sharpen command (see page 8-6). This filter also works well when
shipping pure black and white images (1 bit per pixel). The optimal setting is
26U.
0U Document image filter off
(default)
26U Apply document image filter for typical document image
n
U Apply document image filter using grayscale threshold n. Use
lower numbers when the image contrast is lower. 1U will have a
similar effect to 22e. Range: 0-255.
V - Blur Image: Smoothes transitions by averaging the pixels next to the hard
edges of defined lines and shaded areas in an image.
0V Don’t blur
(default)
1V Blur
W - Histogram Ship: A histogram gives a quick picture of the tonal range of
an image, or key type. A low-key image has detail concentrated in the
shadows; a high-key image has detail concentrated in the highlights; and an
average-key image has detail concentrated in the midtones. This modifier
ships the histogram for an image.
0W Don’t ship histogram
