You can use the Measurements palette.
Working with opacity
Opacity is applied at the color level, so you can specify opacity for just about anything
you can apply a color to, including the first or second color in a blend. This means
you can have different opacities at work on different attributes of the same item a
text box frame, a background, a picture, and each character of text, for example, can
have differing opacities.
Specifying opacity
Specifying opacity is as easy as specifying the shade of a color. In fact, wherever you
can pick a color in the Colors palette, the Measurements palette, the Style menu,
various tabs of the Modify dialog box, and more you can enter an opacity value
from 0% (transparent) to 100% (opaque) in 0.1% increments.
To specify opacity for a picture:
(Windows only) Enter a value in the Opacity field of the Picture tab (Item > Modify).
(Mac OS X only) Enter a value in the Opacity field of the Picture Box tab of the
Measurements palette.
Specifying opacity for groups
Keep in mind that when you stack items of varying opacities, the colors are combined
and may produce a buildup of ink. For example, if you place a yellow box with a 30%
opacity in front of a cyan box with 100% opacity, the box in front will become slightly
greenish.
You can control this by grouping items and specifying a group opacity rather than
individual item opacities. To do this, on Windows, use the Group Opacity field in the
Group tab of the Modify dialog box (Item menu) and on Mac OS X use the Home tab
of the Measurements palette. Depending on the effect you want, you may need to
revert the Opacity field for the individual items to 100% (otherwise, each item's opacity
is added to the group's opacity).
With these three grouped items, compare individual item opacity to group opacity. At
left, each item is 50% opaque the items in front compose against the items behind
them. At right, each item's opacity is 100% while the group's opacity is 50% the entire
group composes against the background. The items in the group, however, could have
individual opacities in addition to the group opacity.
