Font and flattening options for PDF
You can set the following options in the Advanced section of the Save Adobe PDF dialog box:
Subset Embedded Fonts When Percent Of Characters Used Is Less Than
Specifies when to embed the entire font (as
opposed to just the characters used in the document) based on how many of the font’s characters are used in the
document. For instance, if a font contains 1,000 characters but the document only uses 10 of those characters, you
may decide that embedding the font is not worth the extra file size.
Overprint
Specifies how to save overlapping colors that are set to overprint. You can choose to preserve the
overprinting or discard the overprinting. If Compatibility (at the top of the dialog box) is set to Acrobat 4 (PDF 1.3),
you can also choose to simulate overprinting by flattening the artwork. (See “About overprinting” on page 490.)
Preset
If Compatibility (at the top of the dialog box) is set to Acrobat 4 (PDF 1.3) and the artwork contains trans
parency, you can specify a preset (or set of options) for flattening transparency. Alternately, click Custom to
customize the flattener settings.
Note:
Acrobat 5 (PDF 1.4), Acrobat 6 (PDF 1.5), and Acrobat 7 (PDF 1.6) automatically preserve transparency in
artwork. As a result, the Preset and Custom options are not available for these levels of compatibility.

Security options for PDF
When saving artwork in PDF, you can add password protection and security restrictions, limiting not only who can
open the file, but also who can copy or extract contents, print the document, and more.
You can set the following options in the Security section of the Save Adobe PDF dialog box:
Encryption Level
Illustrator uses the RC4 method of security from RSA Corporation to password-protect PDF files.
Depending on the Compatibility setting (in the General section), the encryption level will be high or low.
Require A Password To Open The Document
Requires anyone who tries to open the PDF file to enter the password
you specify.
Document Open Password
Sets the password to protect the PDF file. This option is only enabled when the previous
option is selected.
Note:
If you forget a password, there is no way to recover it from the document. It’s a good idea to store passwords in a
separate secure location in case you forget them.
Use A Password To Restrict Editing Security And Permissions Settings
Restricts access to the PDF file’s security
settings. If the file is opened in Adobe Acrobat, the user can view the file but must enter the specified Permissions
password in order to change the file’s Security and Permissions settings. If the file is opened in Illustrator, Photoshop,
or InDesign, the user must enter the Permissions password, since it is not possible to open the file in a view-only
mode.
Permissions Password
Sets the password to protect the PDF file. This option is only enabled when the previous
option is selected.
Printing Allowed
Specifies the level of printing that users are allowed for the PDF document:
•
None
Prevents users from printing the document.
