Digital BW, The Print

With the Silver Rag Yellowing thread in mind I went through my 
collection of SpectrumViz paper samples gathered in 6 binder maps. Maybe 
250 samples of the Matte Art, Fiber/Baryta, Ori\ufffdntal, RC category. Porch 
shadow daylight inspection, so ample UV light. 2 samples showed 
yellowing at the edges in that light but little with other light 
sources: Moab Entrada Rag Bright 190 and 300 gsm. Light entering the 
binder maps in their boxes obviously the cause of the yellowing in this 
case.

Plain inkjet paper qualities showed more yellow edges in general but 
some sample were more than 10 years old. Not meant for quality prints 
either.

Two papers had had insects moving around it seems, a small yellow path 
was traced on them, probably secretion of the insects left in the paper. 
I have also a bare print upstairs with a nice blue sky that shows 
identical traces in that blue, they probably loved the color.

All in all I am not unhappy with the results, most paper samples are in 
the binders for about 4 years now. Air exposure is higher than when 
framed, light exposure is reduced and uneven but every binder is at 
least twice a month opened for one reason or another.
