•
Export a file that contains transparency to a vector format that does not understand transparency (such as EMF
or WMF).
•
Copy and paste transparent art from Illustrator into another application with both the AICB and the Preserve
Appearance options checked (in the File Handling & Clipboard section of the Preferences dialog box).
•
Export in SWF (Flash) or use the Flatten Transparency command with the Preserve Alpha Transparency option
selected. This command lets you preview how artwork will look when exported in SWF.
For more information on creating and printing transparency, see the Transparency white paper in the Adobe
Technical Info/White Papers folder on the Illustrator CD. You can also find more information on printing and
flattening files with transparency in the Adobe Illustrator User to User forum. This is a public forum that offers a wealth
of tips and answers to frequently asked questions, and can be found at www.adobe.com/support/forums.
File formats that retain transparency
When you save an Illustrator file in certain formats, the native transparency information is retained. For example,
when you save a file in Illustrator CS EPS format, the file contains both native Illustrator data and EPS data. When
you reopen the file in Illustrator, the native (unflattened) data is read. When you place the file into another appli­
cation, the EPS (flattened) data is read.
Note:
Adobe InDesign can place Illustrator’s native and PDF 1.4 files with transparency intact and unflattened. For best
results retaining transparency without flattening using PDF with InDesign, save your files as PDF 1.4 rather than PDF
1.3 or PDF 1.5.
If possible, keep your file in a format in which native transparency data is stored, allowing you to make edits as
necessary.
