Product information

pdfChip is a command-line application for the creation of high-quality PDF from HTML (taking full advantage of CSS and JavaScript). It supports all HTML features, but extends to support CMYK, spot color, XMP metadata, PDF standards, SVG, MathML, barcodes and more. Capable of generating single and multi-page PDF documents it is ideally suited for high-volume dynamic PDF generation.

Based on established technology

pdfChip creates high-quality PDF from HTML, taking full advantage of styling with CSS3 and optionally augmented with JavaScript. A good understanding of up-to-date web technology is sufficient to get started with pdfChip. There is no need to learn custom XML or XSL-FO based languages; anything that works in HTML is immediately usable in pdfChip.

Support for high-quality PDF

Standard HTML and CSS are limited with regards to color spaces, prepress related features like overprint, or advanced pagination. pdfChip extends the syntax of HTML 5, CSS3 and JavaScript to provide support for often needed professional publishing, print, document exchange and archival features. Some of the extensions to HTML5 and CSS3 are:

  • Advanced color space support (including support for CMYK, Lab, ICC-based color spaces and spot colors)
  • Lossless import of CMYK JPEG images, PDF pages and SVG
  • Generation of XMP metadata
  • Generation of standards-compliant PDF/X and PDF/A files

Support for advanced pagination

pdfChip provides custom JavaScript functions and objects for full control of the PDF output process. This includes extensive support of variable data type scenarios where a basic HTML template is modified at runtime using JavaScript, and pages are output for as many instances as necessary (for example based on data dynamically retrieved from a database). pdfChip can also output long documents (such as for example books). It includes a multi-pass option for advanced pagination, supporting page numbers, running headers and context dependent backgrounds or overlays.

Barcodes and other advanced content

HTML already provides numerous possibilities to describe content and apply styling; pdfChip takes this one level higher and also supports advanced scenarios. SVG is fully supported, both inline in HTML files or as a referenced SVG image; conversion from SVG to PDF is carried out without any loss of quality. MathML is also fully supported, introducing high quality PDF representation of formulas of any complexity; this is especially important for text book or scientific publishing.

And last but not least pdfChip incorporates full-featured barcode functionality. Barcodes can be inserted through easy-to-define custom objects; pdfChip supports over 100 types of barcodes used throughout the world.

Command-line processing for easy integration

pdfChip is a command-line application. Because it is easy to install (installation is basically extraction of the installation archive) and has a clear and easy-to-learn command line interface, it’s ideally suited for use on a web server to provide dynamic PDF creation. But it can just as easily be integrated in a custom application or be driven by automated solutions such as Laidback FileTrain or Enfocus Switch.

Wide applicability across different markets

With its extensive feature set and high-quality PDF output, pdfChip is ideally suited as the back-end PDF creation solution for many different applications, amongst others:

  • Imposition and content aggregation workflows
  • Composition workflows where templates and user contents have to be combined on the fly and where printable PDF documents have to be delivered
  • On-the-fly preparation of magazine, newspaper and book content or sales literature
  • Dynamic generation of one-off content such as tickets, stubs, order data, invoices … (for example in web-to-print environments)
  • Variable data printing where templates have to be filled with data coming from a data source (such as a database or CRM system)
  • Transactional printing workflows where transactional data needs to be combined with visually rich designs

CS Labels Xpert intervention by Digital Printer magazine

CS Labels’ managing director Simon Smith: "This has been a steep learning curve but a very worthwhile process."

Being at the forefront of technology innovation brings its own pressures. At CS Labels in Willenhall, near Wolverhampton, innovation is seen as a point of differentiation, and that spirit saw it become a beta site for Xeikon’s new 30 metres per minute Cheetah press in March. It is, says managing director Simon Smith, 58% faster than other Xeikon presses (CS Labels is the largest reel-fed Xeikon house in Europe with five machines). Therein lay the issue however.

"While we were putting the press in, we also had to consider what we were doing in terms of streamlining studio processes to get the work through more efficiently. We were using a preflighting system but it wasn’t giving us the savings we were hoping for", he told Digital Printer

The company had met MyPressXpert sales director Kevin Caughtry at an EasyFairs event in February, and then spoke to Niall Coady from the colour calibration firm shortly afterwards at a Xeikon Café. In talking, it was recognized that there could be ways to simplify and improve the workflow at CS Labels and reduce errors in prepress.

Initially, Mr Coady worked on developing a customised, simplified report for the CS Labels sales team that showed the ink consumption required for a file received, allowing them to quote accurately on the job. It would also preflight the file and report on any fixes that needed to be made, allowing this to be done by the customer before it took up studio time. A second, more detailed, report and client proof PDF is also produced for the studio. This was all achieved to CS Labels’ satisfaction using callas pdfToolbox Server and pdfChip software (HTML5, CSS and Javascript technologies used to automate client proof creation) alongside Filetrain, a workflow management system from Laidback Solutions.

Following this, MyPressXpert has undertaken further bespoke project work for CS Labels, creating a brand new job management system for the Xeikon workflow from scratch, which interrogates an Excel (.xlsx) file from the client and automatically creates and databases all the label barcodes based on sites and quantities. It has also put in a colour management software system – ColorLogic’s ZePrA colour management server and ReProfiler Digital colour engine – which is helping to improve CS Labels’ management of process control and calibration of the Xeikon engines, providing detailed reporting on the stability of the presses so that maintenance schedules can be optimised. This has been effective to such a degree that in September the label producer stopped using the colour control system that comes with the Xeikon presses.

"All digital presses face the challenge of colour consistency from print run to print run, and we also need to ensure that our presses are optimised to achieve Pantone colours", said Mr Smith. "Invariably we are given a label to match by printing CMYK. We need to get as close as possible to achieving the Pantones consistently and measure how close in Delta E we are. This system has helped us to do that. We are of the opinion that it actually takes it to a different level."

The impact of these implementations of automated preflighting and colour management within the company is that CS Labels is able to cope with higher volumes of work while utilising the same level of human resources. "We are also shortening lead times to get work on press and we are getting far fewer mistakes where files have to go back to the studio", Mr Smith continued. "It has streamlined the whole process for us and allows the studio to move away from more mundane tasks such as putting the bleed on a hundred files – those things are automated now. The system also automates the artwork and sends a proof back to the customer."

"The ideal is that we get a PDF from our customer and it goes straight on press without a human touching it. That’s what we are looking for, and we are making fairly substantial progress."

All progress in this direction is welcome, because in December a second Cheetah press will arrive, and further efficiencies will need to be found.

"This has been a steep learning curve but a very worthwhile process", Mr Smith concluded. "The biggest benefit is that we have been able to make this system bespoke to our unique requirements, rather than buying one off the shelf."

Installing on Mac OS

Question: During installation, I got a warning that the developer cannot be confirmed?

Answer: callas software is a registered developer at Apple for MacOS. Due to some quite strict security settings starting with MacOS 10.7 only software downloaded from the Mac App Store can be installed directly. Just change the system settings in 'Security and Privacy' to 'Mac App Store and identified developers' before installing a callas software product. You can set it back to 'Mac App Store' after the installation of course.

General questions on callas software products

Question: What is the target user group of the callas software pdfToolbox products?

Answer: pdfToolbox Desktop is targeted towards people who want to manually inspect or correct PDF files. It can be used either as a plug-in for Adobe Acrobat or as a standalone application (without requiring any Adobe software to be installed). pdfToolbox Server is oriented towards environments where fully unattended inspection and fixing is required. It can be configured with hot folders (also called watched folders) or can be integrated more closely into a solution using the available command-line interface.

Question: I am using pdfToolbox Desktop or Server 6.0 or older. Can I get the latest version?

Answer: Yes you can. Whether this will be with or without cost depends mainly on whether you have an active maintenance agreement for your software. Please contact your reseller or send an email to orders@callassoftware.com to inquire about more details.

Question: Do I need Adobe Acrobat Standard or Professional to process PDF files with the callas software tools?

Answer: No. You can use pdfToolbox Desktop as a plug-in for Adobe Acrobat is you choose to do so, but it can also be used as a completely independent application. The automated solutions (pdfToolbox Server / CLI) are always completely independent.

Question: Are the demo versions identical to the full versions?

Answer: Yes, the demo versions are fully-functional. However, they have a restricted lifetime. You can test our software for 15 days without restriction or obligation.

Question: Where can I buy your products?

Answer: callassoftware has an extensive list of partners that can provide local support and help with training / installation when required. You can find the full list of partners here. Alternatively the interactive products can be bought from the callas web shop here.

Question: Who do I contact if I have general questions on a product?

Answer: Your first point of contact should always be the local reseller; they are able to provide you with local support in your own language. Alternatively, send an email to us directly and we will be happy to help. Use info@callassoftware.com for general questions and support@callassoftware.com for technical inquiries.

Question: I’m experiencing problems when installing or uninstalling software. Where can I get help?

Answer: Your first point of contact should always be the local reseller; they are able to provide you with local support in your own language. Alternatively, send an email to us directly and we will be happy to help. Use info@callassoftware.com for general questions and support@callassoftware.com for technical inquiries.

Question: How can I update my callas software product?

Answer: It’s really easy to update a callas software product – you simply install the new version on top of the old version. As always it's safest to make sure you have a backup before you install new software on a production machine; specifically of the preferences folder where all of your custom profiles are stored.

Question: How do I find out when the new version of my software is available?

Answer: Customers who have a software maintenance agreement (SMA) automatically receive a notification informing them of all version changes for callas software. They can also access detailed information on the changes made in the special SMA area of the callas software web site. Alternatively check our download page; this always lists the latests versions of all products.

Question: I urgently need a particular additional function for a callas software product. What can I do?

Answer: At callas software, we are constantly striving to improve our products. Past experience has shown us that it pays to collaborate with customers on solutions and enhancements to the CLI versions. These functions can be tested on site in real production environments and then integrated into the standard version later on. If you have questions or suggestions, please send an e-mail to technology@callassoftware.com.

Question: Where can I exchange information with other users?

Answer: callas software has a forum where interested users can exchange information about their experiences and specific usage conditions and discuss the integration of callas software into their existing workflows. Click here to visit the forum.

You might also like to visit the Swiss-based site www.hilfdirselbst.ch (German only). It contains prepress forums on the professional use of software for prepress processes, color management, and further processing. Many valuable posts about using our tools in your daily work can be found here.

Question: Is it possible to exchange profiles between different program versions?

Answer: Generally exported profiles are interchangeable within the same program generation (eg pdfToolbox 7.x). Of course, new corrections or checks that have been added in a minor update version (eg pdfToolbox 7.x), are not usable in older versions (eg pdfToolbox 6.x ). As new major versions can include fundamental changes in the profile structure, the profiles have an internal versioning. Therefore, older versions can not import the profiles of newer versions. Since these profile versions can be of interest to integrators and developers, please find the list with versions below:

pdfToolbox version Profile version Acrobat version
4.0 6.0 9.0
4.4 8.0 -
4.5 9.0 10.0
5.0 10.0 -
5.5 11.0 11.0
6.0 12.0 -
7.0 13.0 -

Activation procedure for pdfChip


To use any callas product on a computer, you need to activate it first. This is true if you have bought a license key but also if you want to run the trial software. This article explains how the normal activation procedure for callas pdfChip works and which steps you have to go through.

pdfChip does not have a user-interface, but is used by a command-line interface (CLI). The application needs a valid activation to run. This activation is bound to the hardware from which the activation was performed.


Activation code request

Open a terminal window and change to your pdfChip installation directory.


pdfChip --keycode <name> <company> <licenceCode> 


  • name: Name of licensee (e.g. "Registered user").
  • company: Name of company (e.g. "User's company").
  • license code: License key obtained from the registration card.
    To make a request for a trial version, please use the keyword "trial" (for a pdfChip  trial version).

The result from pdfChip will be a number of lines of text. This text content needs to be sent to the callas activation server; the email address to be used is included in the text output.

After sending the email, the callas activation server sends a return email with the activation information attached (in a text file called "License.txt"). You can send the email to the callas activation server from a different system, but the return activation information will only be valid on the system where you ran the command in pdfChip.


After receiving the automatic email reply, the attached license file has to be saved and pdfChip has to be activated.


pdfChip --activate <license file>


  • licence file: Full path to licence file.
