pdf evolution iso standards subsets versions and types

The Portable Document Format (PDF) was created by Adobe in the last decade of the 20th century. The format was developed with the idea that every document should be readable and printable on any device while preserving the fidelity of the content. As expected, the format wasn’t popular from the start. Nevertheless, the PDF evolved steadily over the years to become one of the most used electronic document file formats today. Here’s a quick overview of PDF versions developed by Adobe. The first version was announced on November 1992 and the first software for handling it was released in June 1993.

The latest PDF 2.0 standard (ISO 32000-2:2020) is now available at no cost. For additional reference, this page serves as an index of the evolution of the PDF format, and includes external links to all legacy Adobe PDF references and errata, as well as to the ISO... https://opensource.adobe.com/dc-acrobat-sdk-docs/acrobatsdk/#pdf-reference – new Adobe resource in May 2022 providing some legacy PDF reference documents only (no errata). https://www.adobe.com/devnet/pdf/pdf_reference_archive.html – original website with all legacy Adobe documents. No longer available except via the WayBack Machine. https://www.loc.gov/preservation/digital/formats/fdd/fdd000316.shtml

The PDF first appeared in 1993 and for most people it is now the de facto way to share digital documents. For those of us using PDFs, or building products that use them, it’s worth knowing that the humble PDF is not humble at all, there are many PDF types, all to given standards. This ‘range’ falls roughly into different ways of categorising PDF types themselves: Technical and Everyday. Technically, PDFs have ISO standards and the like, standards for different business sectors and archiving, for engineering and for printing. There are point releases (have you heard of PDF 2.0?) and subsets (surely you know PDF/VT?), none of which, like any good ISO, impinge on our daily life, but are the hidden backbone to... Of more interest to most of us are what PDFs there are in everyday parlance, this is much simpler to grasp.

Depending on the way the file originated, there are three main types of PDF documents. How the PDF was originally created defines whether the content of the PDF (text, images, tables) can be accessed or whether it is “locked” in an image of the page. Below I take a quick look at everyday PDFs. Real PDFs, also known as digitally created PDFs are ideal for most applications. This is usually the ideal PDF that allows the users to mark up, annotate, search, and copy/paste. Without having to do an extra step.

You can easily create them in-app or via the “print” function. You can search these types of PDFs by default, and content such as text and images copied /pasted into other file formats. There are numerous ISO standards dealing with PDF. Below you will find an overview of the different standards, with a focus on PDF/A and PDF 1.7. PDF Tools AG, as a member of the ISO committee for PDF/A and PDF 1.7, contributed extensively to the development of these standards. The standard PDF/A (ISO 19005) defines the archiving of electronic documents as PDF.

The PDF/A standard ensures that the visual appearance of electronic documents is preserved over time. This guarantees the readability of PDF/A-compliant documents. PDF Tools and its experts play a leading role in the further development of the PDF/A standard. On our knowledge base about PDF/A you can learn all the details about this standard format. In order to further increase acceptance of PDF, Adobe Systems submitted PDF Version 1.7 to the ISO for standardization at the beginning of 2007. Already on July 1, 2008 ISO 32000-1 was published, turning the basic PDF into an ISO standard.

Before the standard could be published, PDF Tools submitted dozens of change requests in order to improve the quality of the specification and resolve long-standing issues. This new version has been created by the ISO members. To make it clear to the outside that this is a new standard, a ‘2’ has been added to the main version number. The list of changes contains more than 50 entries, which contain new features, improvements - but also the cleanup of legacy issues. The new part of the standard mainly concerns the chapters: rendering, transparency, digital signatures, metadata and accessibility. PDF/UA has been an ISO standard since 2012 (14289).

The format aims to make PDF documents accessible to people with disabilities. The standard includes guidelines on how PDF documents and the information elements they contain, such as graphics, text, multimedia elements and form fields, must be made available so that they can navigate in the... This page provides a mapping between ISO document numbers, parts and publication years, and the PDF nomenclature commonly used in industry. The PDF Association maintains a list of published and work-in-progress ISO work items, while the official ISO sites for ISO TC 171 and ISO TC 130 provide additional information. Note that some ISO publications also have associated errata, known as technical corrigenda or amendments, which need to be read in conjunction with the related ISO standard. Withdrawn publications are shown for completeness, as these may be explicitly referenced in other sources.

In some cases, a withdrawn publication may have been replaced by an updated document, as indicated by the year of publication. Withdrawn ISO standards remain available for purchase using the following manual process as documented on the ISO Store FAQs under "How can I purchase a withdrawn standard?": Withdrawn standards are available for sale in PDF or paper version, for the price of CHF 58.00 (+ Shipping & Handling for the paper copy). Withdrawn standards can only be purchased by contacting the ISO Customer Care Team, Opening Hours: Monday to Friday, from 9:00 to 12:00 and from 14:00 to 17:00 (UTC +1). Or by contacting your national ISO member directly. Ensuring the world’s most popular document format is as relevant as ever.

PDF format has come a long way since it was first developed in 1993. Defined by an ISO standard since 2007, the world of PDF technology now includes a multitude of ISO standards, testimony to the breadth and depth of the format’s reach throughout the global economy. Standardization is vital to PDF’s magic as it enables it to look and function the same way everywhere, regardless of the location or software used. The core standard for PDF has just been updated to align with industry needs and requirements that have evolved since its last revision in 2017. ISO 32000-2, Document management – Portable document format – Part 2: PDF 2.0, specifies a digital form for representing electronic documents, enabling users to exchange and view electronic documents independent of the environment in... The document is intended for developers of PDF writers, PDF readers and interactive PDF processors.

The thousand-page standard has been updated with hundreds of corrections and clarifications. Some of the most notable changes include: ISO standards are international guidelines that support organizations in developing their operations and ensuring quality throughout an organization, ensuring safety and/or improvements in efficiency in various industries. ISO standards provide a structured framework for organizations to implement improvement processes, which help ensure consistency, customer satisfaction, and compliance with regulatory industry standards. This blog will cover the types of ISO standards, an overview of possible industry use cases and some corresponding benefits associated with their adoption to your organization.

ISO (International Organization for Standardization) develops internationally recognized standards that guide organizations in delivering consistent quality, managing risks, protecting the environment, and ensuring safety. ISO has published more than 25,000 standards, covering sectors from manufacturing and healthcare to energy, IT, and food safety.
