Defining Trapping Rules and Exceptions
3. To define how two colors trap to each other, select them in the FROM
COLOR and TO COLOR list. In the figure above, a rule for C100 trapping
against Y100 is set up, for example.
4. Using the list to the left of the NEW COLOR
option, choose between AUTOMATIC TRAPPING,
NO TRAPPING, CHOKE and SPREAD.
5. The result of the exception rule can be controlled immediately:
The color boxes to the left of the list
display the two selected colors, the
color resulting from mixing both and
the trap mode (choke or spread)
New color in trap area
Choke
Spread
6. If you have selected CHOKE or SPREAD, you can adjust the new color
used for the trap area. To do so, modify the amount of color used from
each of the two colors that trap against each other.
Use the sliders or enter the percentage values into the input boxes.
7. If you want to use an entirely different color for the
trap area, enable the NEW COLOR option and click on
the color box to its right. Now select a color from the
COLOR SELECTION dialog (see page 10-8).
8. In the RULES button group, click on ADD to create the exception rule.
It is added to the list at the top.
If there is already a rule for the current color pair, the REPLACE button
is available instead. It allows you to overwrite this rule. Using the
DELETE button you can remove exception rules.
To hide all rules except those defined for the color selected in the list
at the bottom left, enable the DISPLAY ONLY RULES OF SELECTED
COLORS option at the bottom of the dialog.
9. When finished, click on SAVE AS to save the exception rules as a
trapping profile. See also page 3-55 and page 3-60.
