Advantages of Exporting to a PDF File
A PDF file encapsulates a complete description of a fixed layout document that includes all the text, fonts, images, and vector graphics. This means that other people see your exact layout, even if they don't have the fonts it includes installed on their machine.
PDF files provide a great way to share your documents with people who don't have Macs. PDF is used for representing documents in a manner independent of the application software, hardware, and operating system. PDF reader software is freely available for most computing platforms.
PDF files can provide excellent print quality.
PDF files are searchable; you can use Mac Spotlight to search for words and phrases.
By printing to PDF file rather than straight to a printer you benefit from generating an electronic copy of all your publications for record and archive purposes.
The PDF format provides space efficiency, which helps to minimise your file sizes.
PDF is widely recognised by different printer drivers.
PDF is an open standard that has been officially published on July 1, 2008 by the ISO as ISO 32000-1:2008.
