Adding transparency effects
When you create an object in Adobe InDesign, by default it appears solid; that is, it has an opacity of 100%. You can
apply effects to objects using opacity and blends. Overlap objects, add transparency to objects, or knock out shapes
behind objects.
About transparency
When you create an object or stroke, when you apply a fill, or when you enter text, by default these items appear solid;
that is, they have an opacity of 100%. You can make the items transparent in a variety of ways. For example, you can
vary the opacity from 100% (completely opaque) to 0% (completely transparent). When you decrease opacity, the
underlying artwork becomes visible through the surface of the object, stroke, fill, or text.
You use the Effects panel to specify the opacity an object, its stroke, its fill, or its text, You can decide how the object
itself, its stroke, fill, or text blend with objects beneath. Where objects are concerned, you can choose to isolate blending
to specific objects so that only some objects in a group blend with objects below them, or you can have objects knock
out rather than blend with objects in a group.
Effects panel overview
Use the Effects panel (Window > Effects) to specify the opacity and blending mode of objects and groups, isolate
blending to a particular group, knock out objects inside a group, or apply a transparency effect.
