Jim, as a matter of fact I recently spoke with a sales rep at Red River Paper here in Dallas (www.redriverpaper.com) and he told me that they are in the process of having Rochester Institute of Technology test ALL of Red River's Papers for archivability with Lysonic inks ...at a cost of $20,000 US. They are expecting results September/October. Jim Davis wrote: <<Rochester Institute of Technology does independent testing, and I would have no problem with trusting their results. They have been around a lot longer than Wilhelm.>> - Please: Stay on topic. Trim quoted messages. http://www.leben.com/lists for list instructions.
