le-tex makes intensive use of cutting-edge technology, including the powerful DTP, image processing, and preflight tools used by other prepress companies.

le-tex mostly processes large data volumes and this requires as much automation as possible. Many of the tools used to do this are more familiar to Unix/Linux programmers. They include the powerful xemacs programmable text editor with many le-tex add-ons, text pattern search and replace using regular expressions, toolchain control with GNU make etc., numerous Shell, Perl, Tcl, or Ruby scripts, svn as version control for tools and content etc. le-tex is particularly experienced in XML conversion with XSLT 2.0 and data checking with Schematron.

However, technology is not an end in itself. Deciding which tool to use for which purpose is also always a pragmatic, economic decision, as is the question of whether an in-house development is required or whether the most sensible approach to the project specifications is to outsource within the partner network. Based on a thorough understanding of customer requirements, le-tex uses pragmatic criteria such as these to decide which typesetting system (TeX/XML, InDesign, Word) is the most suitable for a given project, or recommends appropriate solutions for managing and searching content.
