result in higher quality, but larger files. Smaller numbers result in greater amounts
of lossy compression, faster transmission times, lower quality, but smaller files.
(Default = 50)
n J Image is compressed as much as possible while preserving quality factor
of
n ( n = 0 - 100)
0J worst quality (smallest file)
100J best quality (largest file)
K - Gamma Correction
Gamma measures the brightness of midtone values produced by the image. You
can brighten or darken an image using gamma correction. A higher gamma correc-

0K Gamma correction off (default)
50K Apply gamma correction for brightening typical document image
n K Apply gamma correction factor n ( n = 0-1,000)
