Nanochrome short term fade test measurements.

2006-02-01 by Greg

OK, nobody kill me, I'm only the guy with the spectro. I just 
finished measuring all the papers, and zipped it up. For those that 
care... You will get Lab, spectral, and status T densitometric 
measuresments (two files for each paper). Each paper is divided into 
the reference print, then the test (faded) print in the same file (I 
was lazy). Please take a moment to notice that there is a paper white 
measurement added. Also notice how the paper white has changed on the 
EEM paper (as well as maybe some others).

Abbreviations shoud be obvious, but here are some that I can remember:

HPRS - Hahnemuhle Photo Rag Satin
EPG - Epson Photo Glossy
EPSG - semi gloss
EEM - Epson Enhanced Matte
Albrecht - Hahnemuhle Albrecht Durer

And again, if you don't like the way the test was done, or don't like 
the results, or really anything else that might be even closely 
related to this, please don't take it out on me, I'm just the guy 
that was willing to measure it. Sorry no cool graphs, the changes 
weren't pronounced enough yet to make a real good visual impact. If 
there was more fading, then I might have made some 2D ab graphs or 
maybe even some Lab graphs to show how much they had changed. If you 
want something that will show a big change, try graphing the spectral 
values for several of the "colors", you might get some info that a 
Lab value would not show (especially paper white for EEM). Spectral 
values start at 400nm.

So with all that said, here you go:

I'll leave it there for a while (a couple weeks at the shortest), but 
not forever. Enjoy
