Digital BW, The Print

Test Description:
- Test began on July 3, 2006
- Printer is R2400 with K3 inks
- A print on Silver Rag, ABW setting 4,16
- Print placed on south-facing picture window sill in south Florida
(sub-tropic zone).  The window has an awning, so the print receives
some direct sunlight in morning and late afternoon when the sun is low
enough to get under the awning ends, plus very bright indirect
daylight all day.
- Room is A/C, so temperature and humidity ranges are moderate. 
- Print is partially covered with a piece of 4-ply mat board.
- Periodic checking for visible changes.

Current Results:
- Now at 1 year and 9 months
- No visible change in paper color (SR is a non-OBA paper)
- No visible change in the ink color or density in any zone

Additional Interesting Info:
- Some MIS R2W-LM ink (carbon w/out toners I think) in a Staedtler pen
was used to label the print.  That writing has faded substantially to
where it's getting hard to read.

The Silver Rag/K3 combination seems to be quite fade resistant.

Clayton
