All Images are Guaranteed Permanent to 50 Years
All images are printed on heavy Arches watercolor paper (140lb), with torn and deckled edges, and showing the Arches impression.
To ensure the greatest permanence, the Lyson E inkset has been selected, which has a life of in excess of 50 years on Arches paper before noticeable fading, as tested by Wilhelm Imaging Research, Inc.
Permanence test results by Wilhelm Imaging, for Arches and Lyson E , are included on Page 2 of their report (in Adobe Acrobat format), which you can view by clicking here. (This will not be readable unless you have the Adobe Acrobat Reader).
