7. Select [OK] to accept the trapping settings, or [Cancel] to
reject changes. More Information...
Usage Advice:
– Generally, a trapping zone above 4 pixels is visually
obvious and not pleasing to the eye. A higher value
should be considered carefully; however, the ability to
set a higher trap zone has been included to give the
user control over individual images that have been
poorly trapped individually.
– Two direction parameters are included because the
feed direction has a marginal effect on image quality.
However, in nearly all cases, the user would set these
two values the same.
8. If you are setting the trap width for a queue, you may choose
to set this option for override by selecting the [Override] check
box in the Color Properties tab.
Making Image Adjustments
The Image Adjustments FAB in the Job Properties: Image Quality
FAB contains the following settings:
• Lightness
– controls the relative brightness of the color in the printer's
gamut
– can be set to the desired level +/-100 units using the spin
box
• Contrast
– controls the difference of tonal gradation between the light
and dark values within an image in the printer's gamut
– can be set to the desired level +/-100 units using the spin
box
• Saturation
– controls the strength or purity of the color in the printer's
gamut
– can be set to the desired level +/-100 units using the spin
box
• Color Cast
these adjustments provide the user the ability to decrease
or increase the amount of any single color. Moving the
slider bar toward any one color increases the amount of
that color by decreasing the amount of its complementary
color.
These adjustments are:
– Cyan versus Red
– Magenta versus Green
