Re: [Digital BW] Re: Optical Brighteners in Inkjet Papers

Six weeks in CA sun through glass results in a large change in EAM.  This is
easily measurable.  But then this isn't North Dakota.  In my opinion EAM
should not be used for anything other than proofing...I don't even use it
for that anymore.  It is not acid free, not 100% rag and has OB's.  It
certainly should never have been called archival...but Epson learned that
the hard way.  I suppose it would be ok for a dark store temporary portfolio
though...I just don't prefer it's surface...I like something with a little
more texture to hid dither.
