Fade test July 2015
2015-07-28 by roark.paul@...
I have posted a scan of my latest fade test at
http://www.paulroark.com/BW-Info/2nd-8wk-Fade-test-7-26-2015.jpg .
In this one I've included a test strip of Claria black only on Epson Premium Photo Paper Glossy. That combination was also tested by Mark at http://www.aardenburg-imaging.com/ . The comparison is interesting. I think my compact fluorescent light with no glass/UV filtering is probably causing the OBAs to burn out disproportionately fast. The higher heat and brightness in my setup is probably also causing the 100% K to fade faster. The midtone test patches look like 8 weeks in my fade tester (which sits in a water bath to keep humidity up) may be the equivalent to, on average, a bit more than AaI&A's 50 MLux-Hrs exposure, though direct comparisons are impossible due to the different fade environments.
There are both 16 week and 8 week samples in this test.
My all-Canon Lucia EX toner blend is in this test. The neutralized Eboni-6 test strip looks good. The toner does lose a little Lab A, but it's well within reasonable limits. Compare the neutralized Eb6 test strip to the fiber based silver print test at http://www.aardenburg-imaging.com/ .
I have not yet fully evaluated the test results myself and probably will not be able to for another week.
