John will tend to bang the drum, but, then, he has a great product, and
the inks are UK made I'm told. With a bulk system the cost is a
fraction of OEM cart's.
AFAIK Permajet use MIS inks from the USA, [this could be incorrect info
tho].

I guess Lyson's would too, to be fair.

I wouldn't say Lyson have <mastered> what I prefer to call Illuminant
metameric greybalance shift, it's not bad though. Unlike the 2000P.
Even the 2100 has it.
Just in case anyone wants to know:
[the <feature> often incorrectly termed <metamerism> (<metamerism> is a
term which, when used correctly, describes a different, but arguably
related, occurrence in colour matching. The best example I've read of
this [thanks Rudy Vonk] is of the woman who buys matching shoes and
handbag under shop florescent lights and finds they are not a match at
all under daylight.), that's a <metameric pair>, sometimes alike,
sometimes not .
In printing (especially on inkjets) the term <metamerism> is often
misused to describe a feature of some inks and / or papers, which shows
up as tonally localised shifts in gray balance, when prints are viewed
under differing illuminants. We're now calling this <illuminant
metameric greybalance shift>, since it's the lightsource that changes
the single object [the print] - the reference, neutral image is
imaginary [so we don't have a <metameric pair>, we never did].

yes
I had a fine time with a client who found it impossible to get rid of
bronzing problems.
Perhaps that's cured now.
Bronzing does seem an issue for ink manufacturers, Fotonics bronze on
some non matte stock, and even the 1290 with Epson inks can bronze on
Epson paper. The 2100 bronzes badly on their own premium semimatte.
Bronzing is not nice.
So I guess the advice is to see the ink you're considering on the paper
you like - printed on the correct printer [hardware and drivers can
influence] - before buying into it.
