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: http://www.dfaprinting.com/nanotest.zip I'll leave it there for a while (a couple weeks at the shortest), but not forever. Enjoy
