Well, that's a very positive spin to put on the matter. I would translate the
Lyson people's statements into plain words like this: "when we developed
this product we ignored the problem of metamerism".

Of course, if Lyson sold the ink with a warning about this (perhaps "this
ink is suitable only for prints to be viewed under 5000\ufffdk lighting")...
