An Interview with Henry Wilhelm

Audio Only Edition

In the late Summer of 2008, I interviewed Henry Wilhelm, the world's preeminent authority on print permanence and the founder of Wilhelm Imaging Research. This interview was conducted on behalf of Epson, to be used as part of their 2008/2009 Epson Print Academy. The clip used by Epson was edited down to 14 minutes for use in The Print Academy.

Because the complete interview contains so much more fascinating and valuable information about current printing technology and materials than can be contained in 14 minutes, with the agreement of Epson we have put together a comprehensive and complete version of this important interview. This runs slightly more than one hour, at some 68 minutes.

We are making it available here online at no charge in two versions. This page contains the interview in audio only format, broken up into eighteen separate files. The interview is also available as a video, with individual topics accessible through Chapter Markers. Otherwise the content is the same.

"These tutorials have made my understanding of much of the digital world so much easier.
It is far easier to watch these two experts and learn than trying to understand from some of the 'encyclopedias' that are on the market, and at a price that is excellent than value for money.
