Thread: Lucia Ink lightfast and durability vs. Vivera or Ultrachrome

Here is the initial Canon press release from 2-21-2006
http://www.wilhelm-research.com/canon/prograf_news.html
in which they say "Wilhelm Imaging Research is currently testing the Lucia pigment-based inks... A review of perliminary test data indicates that prints made with the Lucia pigmented inks and slect Canon photo and fine art papers will have WIR Display Permanence Ratings in excess of 100 years for color images and significantly beyond that for monochrome. The pigmented inks also provide excellent short term color drift behavior which is critically important for color managed workflows and for proofing applications."

The long delay in the release of the final report though has been of great concern in recent months.

At http://www.usa.canon.com/consumer/co...&modelid=14005 canon now provides the:

This looks pretty respectable and plenty acceptable to me. I'm glad they released this at last. I will be quite happy with 95+ years permanency!
