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.
Information on International Standards for PDF, including PDF/A for archiving and PDF/VT for variable data and transactional printing, and how they contribute to a holistic approach for enterprise content, output and document management.. Do you know all you need to about these emerging standards?
The International Standards Organization (ISO) has published the second part of the PDF/A standard in the form of ISO 19005-2.PDF/A-2 allows JPEG2000 compression, supports transparency effects and layers, embedding of OpenType fonts, and digital signatures. It also allows archiving of sets of documents as individual documents in one file. Would you like to attend one of our free webinars?
Millions of US citizens use assistive technology (AT) to read electronic content. A decade ago, the US Federal government’s Section 508 regulations, designed to ensure equal access to information, went into effect. 10 years later, it’s time to reflect, both on how far we’ve come and on some of the little surprises along the way.

Your encryption is only as strong as your password. Using AES encryption, alphanumeric passwords of more than 6 characters and other tips are the subject of PDFlib’s security recommendations article.
PDF can encode various restrictions on document operations, such as printing, editing, copying and extraction, and signing, based on permission settings. Permissions can also determine if a document is encrypted in all or in part, or encrypt an attachment. Would you like to learn more about permissions?
PDF offers a host of security options for document protection. From user and master passwords to open files, permission settings for printing or extracting text, to encryption, information contained in a PDF document can be protected in a number of ways. Would you like to learn more?
