Mark,

If you are using EAM, it might be old stock since EAM has been 
replaced with EEM.  Both papers have brightners which make the paper 
appear whiter.  If you expose this paper to strong sunlight or let 
the paper get a little age on it, the brightners will fade and the 
natural yellowish paper base will show up.  Generally, this color 
should be stable.  However, the paper is not archival....that's why 
Epson changed the name to EEM.  The paper is not acid free and after 
about 30 years, the acid should start attacking the paper.

If you like the way your images look on EAM/EEM, you might use Epson 
Velvet Fine Art paper for your print sales....it has the same 
coating, but the brightners appear to be stable and the paper is 
acid free.  This paper is the same paper as Somerset Photo Enhanced, 
but it has the Epson coating.

Many printers are using PhotoRag....but this paper prints with a 
lower Dmax if you are using Ultrachrome inks.  If you are using 
PiezoTone inks, PhotoRag gives a higher Dmax with this ink, so this 
would be a good choice for your fine art prints.

There are other acid free fine art papers available.  Several online 
vendors sell them.
