In the late Summer of 2008 I (Michael Reichmann)
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 video full interview. It also also available in audio-only format broken into 18 separate segments for ease of finding specific topics and for readers with slower online connections.
