Difference Between PDF and PDF/ A

The traditional PDF document format relies on lots of external information when a document is created. This external information can fonts used from external font libraries, third-party encryption algorithms, or some external color scheme. A drawback of this external information usage is that standards often change in the long run and it is not possible to retrieve the same information from the document as it was encoded. Long term data storage is not feasible with traditional PDF encoding. PDF documents are the most widely used documents.

PDF is a standard for encoding documents in an "as printed" form that is portable between systems. However, the suitability of a PDF file for archival preservation depends on options chosen when the PDF is created: most notably, whether to embed the necessary fonts for rendering the document; whether to use encryption; and whether to preserve additional information from the original document beyond what is needed to print it. It identifies a "profile" for electronic documents that ensures the documents can be reproduced exactly the same way using various software in years to come. All of the information necessary for displaying the document in the same manner is embedded in the file. This includes, but is not limited to, all content text, raster images and vector graphics , fonts, and color information.

But did you know that you can tailor your PDF format even more to better suit your business needs? This means of preservation allows PDFs to be self-sustainable. However, for this format to achieve self-sustainability, it must exclude certain features allowed in standard PDF files such as movies, sound, and transparency. Currently, many businesses archive their documents by keeping hard copies paper. Another current archiving method is the use of microfilm and microfiche. For your business, this means a low cost, low volume alternative to keeping stacks of papers and folders in your archive. Also, because this is an electronic format, you can easily store your archived documents in multiple locations making them much less vulnerable to fires, floods, or any other natural disasters.

Instead of endless filing shelves and ring binders for paper documents, our modern digital world asks for a method that ensures the easy retrieving and displaying of documents over an extended period of time. In the US such recommendations exist in the fields of jurisdiction and libraries. They all rely on a preservation that ensures that electronic documents can be reproduced for many years, and in the exact original way, even when using different software.

Here it is recommeded to access-control the storage locations instead in order to keep the files secure.
