PDF/A is basically a PDF format designed specifically for long-term digital archiving. It combines the benefits of PDF with other specific requirements for long-term archiving.PDF/A standards are a set of rules that define what criteria a document must meet in order to be PDF/A compliant.pdf to word converter offline software free download full version It is much more restricted in scope than PDF because PDF itself is the basic standard. Traditional archiving methods (paper, microfilm, microfiche) are no longer compatible with the latest technology while ensuring reproducibility. Traditional PDF formats are in steep decline because they no longer meet the needs of companies in the context of digital transformation. Legal conditions, industry-specific regulations and internal guidelines must also be considered for any given archiving concept. Many organizations create TIFF files as a first step towards electronic archiving. TIFF format files can now be distributed quickly and easily across globally networked organizations; however, searching is still difficult. Conventional PDF format does not fully meet the requirements of an archiving format, which is why it was used as a solid basis for the development of the PDF/A standard.
The difference between PDF and PDF/A
The ISO standard 19005 defines a PDF-based file format called PDF/A. word to pdf converter online i love pdf This format provides a mechanism for representing an electronic document that maintains its visual appearance unchanged over time, independent of the tools and systems used to produce, preserve and reproduce it. This standard does not specify either the method of preservation or the intent or purpose of preservation. Thus, the standard is intended to ensure that electronic documents can be viewed in their original appearance even in the future. As a result, documents may not make indirect or direct references to external sources, such as external images or fonts that are not embedded in the document itself.
Normal PDF format issues cannot be guaranteed long-term reproducibility or complete independence from software and output control devices.merge word documents online i love pdf In order to be able to guarantee these two basic principles, it is necessary to both limit and extend their existing PDF specifications. Obviously, from one aspect, PDF/a-1 must be based on existing PDF versions in order to gain acceptance by a wide audience in society. ISO TC 171 uses Adobe's PDF Reference 1.4 (acrobat5) as the basis for the PDF/A standard (ISO 19005). It states that PDF/A "must continually meet all working requirements for PDF reference-related documents, including this important part of the ISO 19005 standard. The standard only describes the differences with reference to the research literature. To completely different understanding of PDF / A, there are also some necessary to understand the PDF reference document 1.4. PDF 1.4 to support certain system features, such as transparency or audio / video content reproduction, is excluded from PDF / A. At the same time, PDF 1.4 includes the PDF reference document, which must continue to meet all the work requirements, including this important part of the ISO 19005 standard. At the same time, PDF 1.4 contains PDF/A must be established in the inclusion of an optional one element. In PDF/A, for example, all of these fonts used must be embedded. In short, PDF/A essentially defines the mandatory, recommended, restricted or prohibited culturally specific attributes set forth in PDF Reference 1.4.
