Optimizing PDF files
You can optimize PDF files for different versions of Adobe Acrobat or Acrobat Reader by choosing a compatibility option that matches the type of viewer used by the recipients of the PDF file. In CorelDRAW, you can select one of the following compatibility options: Acrobat 4.0, Acrobat 5.0, Acrobat 6.0, Acrobat 8.0, PDF/X-1a, PDF/X-3, or PDF/A-1b.The available controls differ, depending on which compatibility option you choose. If you are publishing a PDF file for a wide distribution, it is better to choose an earlier compatibility option such as Acrobat 5.0 or 6.0 to ensure that the file can be viewed in earlier versions of Acrobat.
To optimize viewing of a PDF document on the Web, you can linearize a PDF file. Linearizing a file speeds up processing time by loading one page at a time.
