Re: [Digital BW] Epson Exhibition Fiber paper white shift at -1.6

2012-04-30 by Phil

Is it possible to translate the test into something easily 
understandable. For example:

In 3 months/6 months/1 year/3 year/10 years/30 years/100 years/300 
years/1000 years, the prints with this paper using an Epson ink will 
yield into:
no image change/10% fading/30%/50%/100% (no image)/paper disintegrate/etc.

Thanks,
Phil
