You guys are a tough crowd ;-)

Ernst: <SNIP... What I did miss in the test is comparing it with "untreated 
Bockingford paper", the watercolour paper you can get in art supply shops . 
Especially when Andrew writes in his conclusion: " It excels in areas where 
prints will be handled, and the "embedded in the paper" feel is a unique--and 
if I might say "IRIS inkjet" look that I remember from using uncoated papers 
with that technology over the years " I would have thought that buying some 
plain Bockingford would have made this test more meaningful.>

Possibly, but I'm not into uncoated fine art papers for inkjet; can't speak 
for Andy.


<I fear it isn't the revolution in inkjet technology as it was presented in 
the PMA report.>

I disagree. Impregnated infusion "coatings" may be the wave of the future. 
That report also mentioned impregnated films and fabrics, which I also saw. 
Time will tell.


Robert: <SNIP... I think this process is only for dye inks.  The only 
application that I could imagine is for dye inks for watercolor images... 
but, once again pigmented inks on another paper would be better for this 
application as well because of longevity....>

Not understanding what you're saying here. The inventor (Edmunds) is claiming 
*increased* longevity on *any* paper the process is applied to. Maybe hard to 
believe, but that's what he's saying.

I'm saying the paper performs terribly with pigmented inks.  I couldn't
possibly imagine using it for anything with pigments.  It is extremely
unlikely, and I say this as a former pigment chemist, that this process will
have any influence on longevity in 100% pigmented inks.  Its possible that
with dye hybrid inks that there may be an improvement...but that depends
completely on the dyes being used.

I've talked with Edmunds on several occasions.  His test results for dye
inks were decent from what I remember, but not on par with what's possible
with pigmented inks.  Now for many applications dyes may be ok...and this
paper...or more specifically, the enfusion process...may be great.
Personally I can't imagine using the Bockingford Inkjet for anything...but
then again I don't print watercolors...but as I said...if it was on a smooth
paper and really did get 60 years...there would certainly be some uses.
