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).
