Digital BW, The Print

In answer to the original question, my strong advice is avoid Lyson
SG 
at all costs. 

If you follow a thread of mine from a few weeks ago ("Lyson Small 
Gamut - Shifting Green") you'll see why. With a pit in my stomach, I 
have been busy recalling 120 prints of mine - both sold and given
away 
- from around the country - in the last two weeks - and ALL of them 
have shifted green from their original sepia hue. I now have to 
reprint all of them. Some were over a year old, some were only six 
months old. All were framed under glass, printed on either Lyson 
Standard fine art, or Hahnemuhle German Etching. (The lead chemist at 
Lyson in the UK told me that they DID amend the coating for the 
Standard Fine Art).

A couple of friends using SG have had the exact same problem.

Just stick with MIS over Lyson whatever you do. Yes, you have far
less 
range in the tinting, the foolish reason I went with SG to begin with 
- but with the metamerism and shifting tones, so what. 

Also, the Epson Ultrachromes on the 2200 using OPM/IJC works 
fantastically too. No metamerism like MIS and real-looking sepia.

In my opinion, Lyson should be run out of business. I've even noticed 
my large-format Iris prints done with Lyson quadtones are a touch 
greener a year and a half after being printed (my large format prints 
are now done sing MIS on a 7500 and look fantastic.)

I'm even worried about using Lyson Print Guard still - has anyone had 
bad experience with that affecting the prints furhter down the line?
