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.

How to Pick the Right Version of PDF/A

The next three categories all address compatibility with three standards to which a PDF file may conform. These standards consist of a set of rules that ensure a PDF file will have the best chance of working well. The three standards are:. The extent to which these standards matter to you depends mostly on what your print service needs. The control settings in Figure 16 are a reasonable choice for a printed document.

The usual purpose of encrypting documents is to prevent restricted material from being viewed by unauthorized personnel. Encryption software is counterproductive for archiving documents because without the encryption key or algorithms or password the archived document cannot be viewed. The encryption might also be subjected to future alterations which will affect access to the document. It means that all content such as color information, text, images, fonts, and other elements must be embedded within the file. It includes fonts from external font libraries, hypertext links, JavaScript, third-party encryption algorithms, external color scheme or data streams. It provides guaranteed reproducibility and it fulfills the requirement that is needed to enable the accurate reproduction of content in the next 25 years or more. So anyone who opens the document in the next 25 years would be able to see the document unaltered.

What are the differences between PDF/A-2 and PDF/A-1?

Microsoft Word or Notepad. Text in the PDF can be indexed for optimizing searching in the document. The entire document is build on the structure that was formed by these tags. This way, searching the document and reusing the contents of the document becomes easier. The document also becomes for accessible for people with a visual handicap. More options?

PDF/A is a subset of PDF that is meant for archiving information. In order to preserve the information in the file and to ensure that the contents will.


What are the Different Versions of PDF/A?

This wizard explains the intents of specific formats as it guides you through the process. If you are familiar with the standards, you can use a built-in profile, or a profile created via the wizard, to convert a PDF. Expand a compliance profile and select the profile you want. If you open a PDF that conforms to one of these standards, you can view the standards information in the Navigation pane.

PDF/A-3 Overview

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. These organizations collaborated together to develop such a PDF version which could avoid the use of external information in document creation and hence the resulting document can be stored for longer periods of time. The content will include color information, text, images, fonts, and other elements.

In addition, while supported in PDF 1. Level u allows organizations to guarantee that document text can be reliably searched and copied -- without the file having to conform to other a-level requirements. They even left the typos intact. B-level conformance requires only that documents conform with guidelines for reliable viewing and therefore, is the easiest level to achieve. Level B conformance conformance level encompassing the requirements of this part of ISO regarding the visual appearance of electronic documents, but neither their structural or semantic properties nor the requirement that all text have Unicode equivalents.

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.

And you may be tempted to go with whatever default setting is prescribed by your converter software. It could be the difference between whizzing through the auto-conversion and validation process -- or expending a lot of elbow grease trying to get files to pass. It could also significantly impact the disk space consumed by your converted files.
