Select the object of which you want to change the
transparency.
Do any of the following:
To change the transparency, move the
Alpha Fill or Alpha Stroke
slider.
If you make text transparent, you may want
to select the Text
knockout option. This option determines how overlapping
characters are shown; if enabled, characters on top will overwrite
("knock out") the characters underneath in the area of overlap.

To change the way in which the colors of the
transparent object on top blend with the colors of underlying objects,
add the required blending modes. Select one or more blending modes in
the Available
list and click the Add or Replace button to put them in the Selected Blending
list. The RIP will apply the blending modes in the order as they appear
in the Selected
Blending list; if it cannot apply the blending mode
which is on top of the list, it will try to apply the second one, and so
on.
Note: For more information about blending modes, visit the
Adobe Web site (www.adobe.com) or refer to
the Help or documentation of your design application (Adobe InDesign,
QuarkXPress,...).
