Typesetting

sigma

Our core activity is typesetting mathematical books and journals for academic publishers.

What is delivered to us: Electronic files, e.g. TeX, Word, graphics, multimedia.

What we do to the files: Copy edit, check style for math, references, clean up or generate graphics, etc.

What we deliver: XML/MathML, PDF, rich PDF, HTML, and whatever else the client requires.

What makes us unique: We generate PDFs fully automatically from XML/MathML.

XML–first — our toughest challenge

Workflow

Publishers rightly demand both PDF and XML from suppliers – PDF for ‘now’, and XML for the future. A problem with XML is that it is very difficult to check for content, because it cannot be easily ‘proofread’ like a PDF file. So it is imperative that when we generate the XML, we can guarantee precise fidelity with the PDF.

Some ten years ago we decided that the only reliable way was to produce the PDF directly and automatically from the XML. This way, checking the PDF would be equivalent to checking the XML. We knew this would be hard, but it proved even harder than we thought, especially with heavy mathematics. But we did it, and now every single page of PDF that we produce, even for the first proof, is generated 100% automatically from the XML file – a true ‘XML-first’ workflow. We believe we are the only company on the planet with this technology for complex text. We have yet to check other planets of course. :-)
