Adobe illustrator 10 Manuale Utente

In contrast, if you target a group that has been created with the Group command and then 
change the opacity, the group is treated as a single object by the Transparency palette and 
the opacities within the group do not change. Only objects outside the group are made 
transparent relative to the group.

Individual objects selected and set to 50% opacity (left). Group selected and set to 50% opacity 
(right).

Before you print a file containing transparency effects, make sure to check the trans-
parency preferences first. Printing automatically flattens the artwork and may affect the 
appearance of the transparency effects. See 

 and 

When you share files between Illustrator and Adobe Photoshop, transparency is 
preserved. Opacity masks in Illustrator convert to layers masks in Photoshop, and vice 
versa. See 

.

Use the Transparency palette to specify the opacity and blending mode of objects, to 
create opacity masks, or to knock out a portion of one object with the overlying portion of 
a transparent object (see 

Displaying the Transparency palette  Choose Window > Transparency.

Using the Transparency palette menu Click the triangle   in the upper right corner of 
the palette to access commands for working with transparency.

Displaying transparency options Choose Show Options from the Transparency palette 
menu. 

You can display a checkered background grid that lets you more easily view the areas of 
the artwork that are transparent when you are working on the artwork.

Viewing the Transparency Grid Choose View > Show Transparency Grid, or View > Hide 
Transparency Grid. 

By default, the entire object (both the stroke and the fill) is affected by transparency 
commands. To change the transparency of only the fill or only the stroke, you can select 
the fill or stroke in the Appearance palette. You can then apply transparency effects to the 
selected fill or stroke using the Transparency palette.
