Exporting and publishing

Last updated 6/6/2015

OPI Lets you selectively omit different imported graphics types when sending image data to a printer or file, leaving

only the OPI links (comments) for later handling by an OPI server.

Preset If Compatibility (in the General area of the dialog box) is set to Acrobat 4 (PDF 1.3), you can specify a preset

(or set of options) for flattening transparency. These options are only used when exporting spreads with transparency

in artwork.

Note: Acrobat 5 (PDF 1.4) and later automatically preserve transparency in artwork. As a result, the Preset and Custom

options are not available for these levels of compatibility.

Ignore Spread Overrides Applies the flattener settings to all spreads in a document or book, overriding the flattener

preset on an individual spread.

Create JDF File Using Acrobat Creates a Job Definition Format (JDF) file and starts Acrobat Professional for processing

the JDF file. A job definition in Acrobat contains references to the files to be printed as well as instructions and

information for prepress service providers at the production site. This option is only available if Acrobat 7.0

Professional or later is installed on your machine. For more information, see Acrobat Help.

Adding security to PDF files

When saving as 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.

A PDF file can require passwords to open a document (document open password) and to change security settings

(permissions password). If you set any security restrictions in your file, you should set both passwords; otherwise,

anyone who opens the file could remove the restrictions. If a file is opened with a permissions password, the security

restrictions are temporarily disabled.

The RC4 method of security from RSA Corporation is used to password-protect PDF files. Depending on the

Compatibility setting (in the General category), the encryption level will be high or low.

Note: Adobe PDF presets don’t support passwords and security settings. If you select passwords and security settings in the

Export Adobe PDF dialog box, and then click Save Preset, the passwords and security settings won’t be preserved.

Security options for PDFs

You can set the following options when you create a PDF or when you apply password protection to a PDF. Options

vary depending on the Compatibility setting. Security options are not available for PDF/X standards or presets.

Compatibility Sets the type of encryption for opening a password-protected document. The Acrobat 4 (PDF 1.3)

option uses a low encryption level (40-bit RC4), while the other options use a high encryption level (128-bit RC4 or

AES).

Be aware that anyone using an earlier version of Acrobat cannot open a PDF document with a higher compatibility

setting. For example, if you select the Acrobat 7 (PDF 1.6) option, the document cannot be opened in Acrobat 6.0 or

earlier.

Require A Password To Open The Document Select this option to require users to type the password you specify to

open the document.

Document Open Password Specify the password that users must type to open the PDF file.

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 Printing, Editing And Other Tasks 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
