Input Levels - Adjust the Black and White Threshold levels
to attain the best looking image. Increasing the black
level will result in a darker image and decreasing the
white level will result in a lighter image. This may result in
loss of gray level information (similar to a contrast
change). Use of the Auto level filter is preferred in this
instance.
Click Input Histogram to view the histogram of the
image before any changes have been made.
Output Levels - Adjust the Black and White Threshold
levels to attain the best looking image. Increasing the
black level cause darker gray levels to be printed
lighter. Decreasing the white level will cause the lighter
gray levels to be printed darker. This will reduce the dray
level range of the image.
Keep Max Threshold - When changing other gray levels
(e.g. Output Levels White Threshold < 255), the value of
a maximum white pixel (tone=255) shall not be
changed. This is useful for pictures that ran through a
background removal algorithm and where the
background is completely white when limiting white
tones to a light gray, however the background shall not
be changed. Note that When opening an older
ConCAD file, this setting is deactivated.
Click Output Histogram to view the image histogram.
This is what will be printed.
Gamma - The Gamma adjusts the gray levels of
midtone values. A higher gamma value yields an overall
lighter image. The correct gamma value depends on
the adjustment of the laser beam train.
For MX6000 systems, the ideal gamma setting is 1.00.
For PB6500 systems, the ideal setting is 2.20.
