pdfaPilot is the solution for conversion of PDF or native documents and emails into robust, searchable PDF or PDF/A files for long-term archiving. It uses the same rock-solid PDF/A technology as used in Adobe Acrobat and is available for desktop use, through watched folders or ready for integration into existing systems through a command line interface or software development kit.
In many environments, there are regulatory requirements that all communication regarding specific topics has to be archived for a certain period of time. How long that is can differ widely – from a few years to multiple tens of years.
The format of choice for archiving is defined in the ISO standard PDF/A (PDF for Archiving). This ISO standard defines three different PDF/A versions and callas pdfaPilot can automatically convert all of your documents and emails into the PDF/A flavor required for your purposes. Additional job information (metadata) is fully supported and the solution is configurable enough to let it adapt to your workflow instead of the other way around.
Archiving documents is a critical operation of modern workflows; for that reason callas pdfaPilot has been extensively tested and complies with the ISO standards as verified with for example the veraPDF test corpus or the Isartor test suite. The fact that the very same technology is used in the de facto standard, Adobe Acrobat, is testament to its quality.
The best way to have good PDF/A files is to properly create them to begin with. For this, callas pdfaPilot can automatically convert Microsoft Word, Excel, PowerPoint, Project, Publisher and Visio files into quality PDF files for you. Simply drag them on the document window of callas pdfaPilot Desktop and the conversion takes place in the best possible way.
LibreOffice and OpenOffice documents are fully supported too and on Mac OS X Pages and Keynote of course work as well. Using the integrated Adobe engine, callas pdfaPilot even does quality conversion of EPS and PostScript files for you, without requiring Adobe Acrobat Distiller to be installed.
These days, emails are an essential part of business communication in most organizations. Many countries have laws and regulations around the archival of such communication, either to be used in potential future litigation or as part of sound accounting practices.
Because emails are usually handled by email servers with limited storage capacities, there are no guarantees that an email you receive today will still be on the server ten years from now. When you download the email from your server it is converted into the proprietary format of the email client, and there is no guarantee that you will have such a client in the future. In addition, there are attachments to the emails that require a proper viewer for all file formats that may occur here. Luckily callas pdfaPilot lets you store these emails including all attachments in a PDF/A format that will be available and readable many years from now.
But even in environments where such regulatory guidelines don’t apply, there are good reasons to archive emails. In our modern society an amazing amount of business intelligence is captured in emails. Being able to maintain that information in a structured way and in the same format that is used for other documents and being able to efficiently search all of those documents including emails and their attachments efficiently will only become more important.
Thanks to its unique checking feature for tagging structure in a PDF file callas pdfaPilot also offers optimized exporting to PDF/UA, the standard for accessibility. More and more legislation requires documents to be universally accessible for everyone, including people with physical disabilities. As a result, checking against the PDF/UA standard has gained importance for service providers, governments and enterprise customers alike.
But pdfaPilot lets you take advantage of PDF tagging in a very different area as well:
The tagging structure can be used in order to automatically create EPUB files from PDF. This PDF to EPUB feature converts PDFs into eBook files that can immediately be used on mobile devices such as smartphones or tablets.

PA Digitale SpA is a leading software solutions provider on the Italian Public Administration market. It specifically targets the document and data management sector.
PA Digitale offers an integrated management information system, called URBI Smart that covers all functional areas of management and provides to Directors/Executives a support tool for real time management. Thanks to the availability of static and dynamic data reports it also offers a complete framework for integration with other data sources that is always up to date.
URBI Smart is completely web based, available in the Cloud, accessible from any PC and mobile device, 24 hours a day, seven days a week.
The PA Digitale software solutions also offer advanced electronic document management, from creation and classification to archiving and digital preservation. These functionalities are available in an integrated Web Portal for a more efficient Public Administration, “closer” to citizens.
With its new WebTec solution, PA Digitale is now not only entering the private market, but also introducing one of the first digital preservation solutions formally approved by the Italian government. callas pdfaPilot enabled PA Digitale to make a big leap forward in terms of management and digital preservation of electronic documents.
“Without a digital preservation service there is no dematerialization of paper workflows. Digital preservation is a key factor for the sustainability of the dematerialization process, to ensure that information and documents are stored in a way that guarantees integrity, authenticity, accessibility and readability.”
May 2014, Agenzia per l’Italia Digitale - www.agid.gov.it
An electronic document, like any document processed by a Public Administration (PA), must be classified, sorted and sent to an archive. Moreover, any Public Administration document is considered a cultural heritage and, for this reason, must be preserved according to government laws.
Public Administrations as well as private companies are obliged to manage the digital preservation of documents in various areas, where law requirements are in effect or imminent. Such documents are for example: electronic invoices, daily PA register protocols, administrative records, contracts, and any kind of document including a digital signature. They are all electronic documents and for this reason subject to digital preservation.
Within the private sector especially for financial accounting documents requirements exist enforcing digital preservation by Italian law. Digital preservation has to deal with the protection of legal validity, authenticity, integrity, reliability, availability and immutability of electronic documents.
PA Digitale’s preservation software solution is developed with the latest innovative technology, including callas pdfaPilot libraries for PDF/A document management. callas pdfaPilot allowed PA Digitale to design a software able to convert any document (generated from any management software on the market) to always-valid future-proof PDF/A documents, ready for the digital preservation process.
“The particular methodologies and technologies used to design and realize our systems also allow us to perform maintenance activities, software updates, etc… without any service interruptions. These features, combined with the web based access mode optimized for mobile devices, allow us to ensure access to the system in any place at any time.”
Explains Fabrizio Toninelli, Administrator at PA Digitale.
This was achieved by replacing the analog model with the digital one and by changing the management processes with the digital preservation objective in mind. Thanks to the callas software solution PA Digitale drives its customers in the right direction.
Mercedes-Benz Schweiz AG wanted to achieve greater transparency, uniformity, security, and compliance in its document storage. With its decision to use consistent electronic long-term archiving in PDF/A, the company is very much following the current trend. Mercedes-Benz Schweiz AG was looking for a flexible, powerful, and stable solution. Today, pdfaPilot from callas software, provider of powerful PDF technologies for publishing, print production, and document archiving, is used for the fully automatic conversion to PDF/A of the 30,000 or so order-related documents that arise each year. Mercedes-Benz Schweiz AG will therefore be able to give up its physical archive and benefit from the advantages of long-term, uniform, digital storage.
Mercedes-Benz Schweiz AG is a subsidiary of Stuttgart-based Daimler AG. As a sales and marketing company with around 400 employees, the company is involved with the registered brands for passenger cars Daimler’s Mercedes-Benz and ‘smart’ and the Mercedes-Benz and FUSO brands for commercial vehicles. For the many documents produced during order processing for vehicle fleet business with suppliers and dealers the company used a document management system in conjunction with its system for order processing, but this did not include an archiving function that enabled documents to be stored electronically in compliance with legal regulations. Instead, the scanned documents were saved in image format and the original documents archived on paper. This resulted in duplicate data retention and a large amount of space required for the physical archive.
In October 2011, when Mercedes-Benz Schweiz AG decided to replace the order processing software, one requirement was that the documents should only be archived electronically. It was clear that the company should use PDF/A, the most suitable format for long-term archiving, in order to meet legal requirements. The search began for a suitable product to put this into practice. “We wanted to offer users the most flexible solution possible. We also needed the conversion to PDF/A happen in the background within the application. We were therefore looking for a stable solution to convert image formats and MS Office documents to PDF/A,” explains Fabrizio Tuena, IT - Business Consultancy & Service Management at Mercedes-Benz Schweiz AG.
The analysis of the market resulted in comprehensive tests on three products that made the shortlist – one of which was pdfaPilot from callas. “We were particularly looking for reliable, compliant conversion to PDF/A format and good performance,” says Fabrizio Tuena. “And of the three tools we tested, pdfaPilot turned out to be the most reliable.” The company chose the pdfaPilot Software Development Kit, the programming library that can be integrated easily and flexibly. During subsequent implementation, various questions relating to installation in a multithreading environment were quickly clarified. Tuena states: “The collaboration with callas was competent and very fast, from sales consulting and implementation right through to support for the ongoing project.”
Document-intensive processes are common at Mercedes-Benz Schweiz AG: The company uses them to commission its suppliers to alter vehicles to meet customer requirements – e.g. including interior fittings for commercial purposes or labeling them accordingly. Dealers then take on final tasks such as handover including registration of the vehicle with the authorities. All order-related documents such as the contract, orders for bodies, delivery documents etc. are scanned and uploaded to the new order processing software. There, pdfaPilot converts all documents to PDF/A, thus making them ready for long-term archiving.
The documents are then given a digital signature to meet the legal requirements regarding proof of immutability. Finally, the documents are archived in a document management system from OpenText.
The project has been concluded in February 2013, and Mercedes-Benz Schweiz AG is very satisfied with the results. “Because conversion is fully automatic, no manual intervention is required. In addition, pdfaPilot is a flexible solution that permits a wide variety of scan formats,” concludes Fabrizio Tuena.
Entry-level PDF/A support, standalone, inside Acrobat or fully automated as Server version
For businesses and government agencies, archives and libraries, that store and long-term maintain documents, callas pdfaPilot is the professional desktop tool to validate and/or create PDF/A-files. It turns all kinds of PDFs into ISO 19005-1 conform PDF/A documents:
With pdfaPilot it is a snap to check whether your documents comply with the PDF/A standard. And if they don’t, callas pdfaPilot contains a wealth of tools to bring them in line. Working as a plug-in inside Adobe Acrobat or as a fast standalone application, callas pdfaPilot offers the broadest PDF/A support on the market in the easiest package. callas pdfaPilot works on single documents or – using its batch functionality – on complete folders at a time.
To process higher volumes of files or to free up operators by hands-off automation, callas pdfaPilot Server provides just that. The hot folder interface lets you setup different watched folders that automatically pick up files and process them. The engine inside callas pdfaPilot is fully multiprocessor aware so it takes advantage of all of the speed available in your server. Additionally callas pdfaPilot Server has load distribution capabilities to enhance performance by using multiple servers. Both the Desktop and Server version run on Mac and Windows. A command-line interface and a full developer SDK are available when closer integration or more fine-grained control is of the essence. With their additional availability on many Unix flavors, the CLI and SDK allow painless integration in a wide range of operating environments. Other supported platforms are Sun Solaris and IBM AIX.
The Rosendahls group is a company with a rich tradition and roots going back to 1902. Located in Copenhagen, Odense and Esbjerg, it has offered a comprehensive range of services in the areas of communication, publishing, warehousing and distribution for more than a century. Rosendahls is on top of new developments and continues to be a technology front-runner to support its customers. As many of those customers traditionally come from public administration organizations, Denmark’s embracing of the ISO PDF/A standard had a direct impact on Rosendahls.
PDF/A, the ISO standard for PDF files to be stored in long-term archives, has been steadily increasing in importance, especially for use by governments and public administrations. In April 2011, the Danish Ministry for Economics, Innovation, and Education decided to require accessible PDF/A documents as the compulsory format for all public sector documents. As a full-service provider, it was important for Rosendahls to be able to convert existing documents to PDF/A and check compliancy with the ISO standard when needed.
The standardisation by the Danish government on PDF/A didn’t take Rosendahls by surprise. While HTML was still the required format for agencies, Rosendahls already saw the European trend towards PDF/A. It started looking for a solution to support this upcoming standard early; the corresponding market research culminated in a visit to the 4th international PDF/A conference in Rome in the fall of 2010. The conference provided a wealth of information and access to experts from the different technology vendors with PDF/A technology.
“This is when we decided to use pdfaPilot by callas software”, Jens Bjerre Kirkegaard, Document Accessibility Specialist at Rosendahls, recalls. “Our requirements for creating valid PDF/A files were best met by pdfaPilot, which also offered convincing reliability and an easy-to-use intuitive operation”. Rosendahls faced additional challenges because it had to be able to provide accessible PDF/A files, which requires support for the technically ‘more challenging’ parts of the PDF/A standard known as PDF/A-1a, but pdfaPilot easily meets those challenges. “On top of that,” continues Jens Bjerre, “callas pdfaPilot offers a range of additional features such as splitting PDF documents or creating hand-outs for example and those come in very handy in our daily use”.
callas pdfaPilot is ideal for the demanding workflow at Rosendahls because it supports direct conversion to PDF/A from a wide range of formats such as Microsoft Office, Open Office, Postscript and a variety of image files. It is built using the same technology licensed by Adobe for Adobe Acrobat and provides seamless scaling for large-volume environments. The fact that so much of the work can be automated gives Rosendahls additional time for the manual steps required for accessible conversion.
For the media services provider who often receives individual documents from many different sources – which creates very different requirements opposed to high volumes that always have the same structure – the ability to automatically convert to and validate PDF/A is particularly important. “We convert either to PDF/A-1a or PDF/A-2a“, Kirkegaard explains, “We usually have to process Word, InDesign, or PDF documents, and callas pdfaPilot automatically resolves many stumbling blocks for us. E.g. it checks for and removes unnecessary metadata, marks or corrects incorrect color spaces or embeds fonts retroactively”.
The fact that the pdfaPilot can ‘repair’ problematic documents or – if this is impossible – recreates them completely from scratch, saves Rosendahls a lot of time and work. But there is still a lot to do for the accessibility specialist Jens Bjerre Kirkegaard: “Provisioning of accessible documents is a demanding and often finicky task which requires a lot of know-how and a few manual steps”, he explains. It is impossible to setup a completely automated workflow, especially when receiving diverse and often-problematic native document formats. But here as well pdfaPilot comes to the rescue by providing manual editing of metadata, colors, images and many other PDF properties.
For challenges surrounding PDF/A and accessible documents Jens Kirkegaard benefits from the fast and competent support of the callas distribution partner Actino Software. “Media service providers such as Rosendahls are often confronted with the fact that customers want their heterogeneous documents provided as PDF/A files but they have no idea how complex the required work really is”, Actino director Michael Karbe explains.
Since the installation of the first version, Actino has been supporting their customer Rosendahls reliably and has worked closely with callas software to resolve any questions or problems that arose during the project. callas software integrated all improvements into further development of pdfaPilot. “The continued development of the PDF/A standard also requires adjustments to the PDF/A toolsets”, Dietrich von Seggern, Business Development Manager at callas software explains. “We are highly dedicated to this area and thanks to constant updates to pdfaPilot, we can ensure comprehensive implementation of all requirements and therefore provide optimal conformity.“
Rosendahls recently migrated to the latest version of pdfaPilot: version 3.0. This version allows embedding documents inside a PDF/A file and implements support for the PDF/A-3 standard. This allows Rosendahls to embed all documents belonging to a certain project or file inside their accessible PDF/A documents. And whenever they want to take advantage of PDF/A-3, the solution is ready for them.
Accessibility and creating accessible PDF files is a topic that really drives callas software and its sister company axaio software. The InDesign plug-in MadeToTag was created by axaio software to simplify and speed-up preparation of Adobe InDesign documents before they are converted into accessible PDF/A files.
Jens Kirkegaard explains its importance: “Accessible PDF files require a clear structure and this is accomplished by adding tags to the PDF. These tags provide additional information about the structure and order of text, provide alternative text to clarify what embedded graphics represent and can discriminate between real content and design elements. These tags are essential for good accessible documents.”
Using axaio MadeToTag, which is now in public beta, it becomes much easier to quickly and reliably add those tags to InDesign documents. Once the document is then converted to PDF, it becomes a high-quality accessible PDF/A document.
“The effort involved in converting agency documents to barrier free PDF/A documents depends on the complexity of the layout. Sometimes one simply reaches the limits of the cost-benefit ratio. For my work, it is a considerable relief to know that a lot of the steps which previously had to be completed by hand are now done by callas pdfaPilot”, Kirkegaard explains.
The PDF/A trend is really taking off in Denmark, so Rosendahls is expecting a major increase in its future order volume. Thanks to callas pdfaPilot and the service from Actino Software, they are already well prepared and equipped for it.
When legislation and practice converge, complying with the regulations is simpler. That’s been the case with the deeds that firms deposit with the Chambers of Commerce Companies’ Register - computer documents that from this year on have to be produced in PDF/A format. Infocamere carries out systematic compliance checks on them using procedures from callas software’s pdfaPilot application, which has been entrusted with the prompt validation of the files sent to the Register.
Michele Piva, Head of Marketing for the document area of the Italian Chambers of Commerce IT department: “We’re dealing with a standard that was already widely in use before the Ministerial Decree (of 10 December 2008 sanctioning its use) came into effect, exactly because it derives from the PDF which firms had been widely using for some time”.
Of the possible candidates for the long term archiving of electronic documents the PDF/A won out over XPS (XML Paper Specification), TIFF G4 and JPEG. “The PDF/A – Piva adds – was set as the standard ahead of the legislation. Infocamere has invested in it both for the necessity of making available documents that must keep their legal integrity and value over time — considering that the elimination of paper is a must in public administration — and because it considers that, as it is a reinforcement of the PDF, the shift over to it could be taken for granted”.
And the statistics are indeed showing this: whereas from the beginning of March to the middle of April already 47% of the deeds presented to the Companies’ Register were compliant with the new measures, the documents deposited in the following month and a half achieved a format validation of over 58%.
“Looking in particular at company constitution deeds, the most frequent type received in total by the Chambers of Commerce among the over 580,000 analyzed in the period under consideration (excluding the documents classified as ‘other deeds’) turns out to have been in PDF/A compatible format. And for a good 89 of the 105 Chambers the percentage of valid ones is over 80%. This is the proof that the adoption of the PDF/A is being generally and rapidly confirmed over the whole of Italy”.
According to the ISO 19005-1 standard, PDF/A offers a mechanism “for representing electronic documents in a manner that preserves their visual appearance over time, independent of the tools and systems used for the creation, memorization and rendering of the files”.
In other words, the PDF/A files are self-contained and, since they incorporate the information (content, colour, image, text and so on) necessary to display the document, they do not require any additional data for its correct visualization. However, exactly on account of this property, the format must exclude determined functions allowed in normal PDF files such as transparency and multimedia content, and cannot include macro-instructions or rely on links to external resources.
The validation check
“In order to facilitate the file production operations — continues Piva — we have also chosen the blandest compliance to the standard – which corresponds to the sub-category PDF/A-1b, for which no explicit logical structure is needed. Despite this we have noted that there are some recurring errors: on the one hand, the poor indexing and aggregation of the deeds attached to the form; on the other, the widespread habit of creating a copy of the document which then doesn’t have the original’s representation (and its metadata) and so loses its validity”.
As well as all this, the possibility of visualizing a document “in PDF/A form” is not in itself synonymous with standard compliance: “It happens — even with Adobe Reader 9, which provides this indication — a source of a widespread error. Thus the only way to ensure adherence to the standard is the validation control”.
To check this it is necessary to use products such as Adobe Acrobat 9 Pro or pdfaPilot from callas software. The alternative is the free service, accessible from the tools section of the WebTelemaco site, which employs the same pdfaPilot tool used by the Companies’ Register office and which enables the validation of any document whatsoever supplying the result online, complete with details of any non-conformities encountered.
Negative outcome — rejected form
“For our validation procedures — explains Piva — we have used the server version of pdfaPilot, which the application we’ve developed makes appropriate calls to, determining the correspondence to the PDF/A-1b specifics. A good number of the people we work with, from service professionals to notaries and accountants, get a great deal of benefit from the tool on WebTelemaco. And, once we’ve received the files, we regularly repeat the checks. If the outcome is negative, the form is rejected”.
“The management application was created over the space of three months from the approval of the Ministerial Decree and required an investment of around 30,000 Euro. An expense which has already been repaid by making available a standard that guarantees long term document validity and integrity: a guarantee of uniformity to a defined standard and, therefore, also of quality. Among the further benefits, apart from the return on image, is the improvement of cash flow, since compliance to the standard ensures that homogeneousness which is a key element for its subsequent conservation and concession — on payment — to distributors and information agencies who use it for commercial purposes”.

Dietrich von Seggern, Managing Director of callas software, hosted this presentation at PDF Days Europe 2018.
This session delivers an overview about PDF/X, PDF/A, PDF/E, PDF/VT and PDF/UA. Their specific use cases are explained and how related requirements are transferred into provisions of the respective standards. The development of the standards also show how the general use of PDF has been changed over time starting with PDF/X where PDF is an intermediate product for printed paper to PDF/UA where PDF is much more than what could be printed.
Dietrich von Seggern, Managing Director of callas software, hosted this presentation at PDF Days Europe 2018.
While font formats have become more modern and overal fonts have become higher quality, problems with fonts and text are still a sizeable chunk of what goes wrong with PDF documents. When looking at PDF 2.0 not much has changed in this area. This session gives an overview about how fonts are used in PDF and in which way this relates to frequent font problems in PDF or PDF/A. As a tool Acrobat Preflight’s PDF Browser will be explained and in which way it can be used to track down text and font issues.
