The long-term archiving format PDF/A is a relatively new standard. This document discusses some of the more technical aspects of PDF/A. If you need to produce files with static content that can be visually reproduced completely precisely today and in many years time, regardless of the device or operating system used, please read more.
The idea behind an ‘improved’ PDF/A-1b is to enhance the conformance level by encompassing the advantages of Unicode. Unicode is obligatory only in PDF/A-1a, but that does not rule out the voluntary usage of Unicode in PDF/A-1b. A new compliance level would give users a better overview of their options. In addition to compliance levels A and B, PDF/A-2, which is currently being compiled, will also include PDF/A-2u (’u’ for Unicode). [...]
A thorough understanding of the PDF/A standard is a prerequisite for the creation of PDF/A-compliant documents, and also for displaying them in accordance with the standard. This knowledge alone is however insufficient for optimally configuring PDF/A-related processes. Would you like to learn about typical processes can be designed, in order that components that are available on the market today can be used to achieve an optimal cost / benefit relationship? [...]
Conformance to PDF/A involves not only the requirements in the ISO standard itself, but also in the secondary specifications. Currently there exists no implementation that can be used as a reference (documented or software). The PDF/A-1a standard distinguishes itself through more detailed requirements than PDF/A-1b. PDF/A-1a requires amongst other things „tagged” PDF and Unicode. If you would like to learn more about conformance and the PDF/A Competence Center’s plan to develop a test suite, please read on.
PDF/A conformance requires a significant effort from the producers of PDF software. [...]
This article deals with color spaces, ICC profiles and output intents. If you would like to learn more about color, it provides several user examples based on Adobe Acrobat 8 Professional, but there are also numerous other PDF/A tools that are not mentioned here. [...]
ISO 19005-1 defines “a file format based on PDF, known as PDF/A, which provides a mechanism for representing electronic documents in a manner that preserves their visual appearance over time, independent of the tools and systems used for creating, storing or rendering the files.” (from ISO 19005-1). The Standard does not define an archiving strategy or the goals of an archiving system. It identifies a “profile” for electronic documents that ensures the documents can be reproduced in years to come. [...]
This test suite comprises a set of files which can be used to check the conformance of software regarding the PDF/A-1 standard. More precisely, the Isartor test suite can be used to “validate the validators”: It deliberately violates the requirements of PDF/A-1 in a systematic way in order to check whether PDF/A-1 validation software actually finds the violations. [...]
The Isartor test suite is available from www.pdfa.org free of charge. It can be used to check PDF validation software and software vendors can use it to “certify” that their products conform in full or in part to the Isartor test suite. A detailed list of test results must be made available as part of the declaration.
