Isolate blending. When you apply
blending modes to objects in a
group, the blending modes affect
other objects in the group as well
as objects beneath the group. If
you select Isolate Blending in
the Effects panel, only objects in
the selected group are affected
by blending modes applied to
objects within the group. Objects
beneath the group are unaffected.
Displaying transparency. The controls
in the Display Performance
pane of the Preferences dialog box
(InDesign > Preferences > Display
Performance in Mac OS or Edit >
Preferences > Display Performance
in Windows) let you set display
options for raster images, vector
graphics, and transparency. If you
set the Transparency slider to Off
(by moving the slider all the way to
the left), transparency effects are not
displayed onscreen but are maintained
when you print or export the
document. The other three slider
settings—Low Quality, Medium
Quality, and High Quality—let you
control the display quality of transparent
objects.

Pages panel. Pages with transparent
objects are displayed with a checkerboard
pattern next to the page number
in the Pages panel.
Flattener Preview panel. When
you print or export an InDesign
document that contains transparent
objects, InDesign performs a process
called flattening, which converts all
overlapping areas in a stack of
transparent objects into a collection
of opaque vector and raster objects
that retains the appearance of the
original objects.
The Flattener Preview panel
(Window > Output > Flattener
Preview) helps designers and printers
prevent mistakes, reduce costs,
and ensure the highest quality
printed results by identifying the
objects on a spread to which transparency
effects are applied or that
interact with transparent objects.
The Highlight menu in the
Flattener Preview panel provides
several options for displaying specific
instances of transparency, including
Transparent Objects, All Affected
Objects, and Affected Graphics.
