On January 15th, 1992 the foundation of my company PrePress-Consulting Stephan Jaeggi was published in the Commercial Register of canton Basel-Landschaft. Despite the fact that preparation work started earlier this marks the offical beginning of my company.
At the beginning my goals was to cover the entire prepress area. I have supported my customers in the evalution and introduction of new hard- and software (from editorial systems to imagesetters). I also did process optimisation and database publishing projects. But soon this became too much to cover and in 1996 I decided to concentrate my activities to the upcoming PDF technology. At the same time I started with my first PDF seminars.
At the beginning the main focus were digital publications of printed material (e.g. annual CDs for magazines, online archives with full-text search). Later PDF became more an more interesting as exchange format for prepress data. Since 1998 I am a technical expert in the ISO committee TC130/WG2/TF2 which defines the PDF/X standards. Shortly after the millenium PDF/X-1a and PDF/X-3 were published. Those have served the industry very well for many years. But recently users more often face issues during output of PDF/X-1a and PDF/X-3. The reason are the transparency features in many layout applications. Since these 15 year old standards do not support transparency, a transparency flattening must take place during export to PDF/X-1a and PDF/X-3. This can lead to heavy quality problems. The risk for output problems (e.g. due to wrong overprint settings) or bright lines between flattened objects increases. In order to avoid transparency flattening during page creation we introduced PDF/X-4 in 2008. In order to facilitate the transition to PDF/X-4 we have also done a lot of work in the Ghent Workgroup (GWG) and PDFX-ready. Recently I was responsible for the development of the to make PDF/X features available to a broader audience.
In addition to printers and prepress service providers, ad agencies and publishers, more and more print buyers are interested in standardizing their digital prepress files. E.g. I have successfully supported Novartis Pharma in the global introduction of PDF/X-4 for all packaging prepress files. An important part of the services is the creation of optimized preflight profiles. Beside consulting I also share my knowledge in many seminars and publications (mainly in german). The most important publication is the free newsletter PDF-AKTUELL published for the first time 1999!
