Re: [Digital BW] acid free Epson paper?

2002-05-07 by J Greer

The lowered rating of EAM for the new printers (2200/7600/9600) may have 
more to do with the new inks than the paper. Epson tried to make the new 
Ultrachrome inks work better with third-party fine-art papers and will be 
introducing a version of Somerset Velvet (don't know if it is 'Photo 
Enhanced' or not) made specifically for Epson and these printers.
