Nick,

I also think that the great divide between prints that fade and
that don't fade yet is in the used papers. Like with all other
dye inks (semi)gloss paper with a gelatine coating can be far
more compatible with the ink than matt coated papers can be.
About 25 years like Wide Spectrum and the Epson 10000 dye ink on
gelatine papers seems to be possible. That is CcMmYK ink, don't
know how long the black inks keep their density though. Don't
think that Wilhelm paid much attention to that otherwise he
wouldn't have rated Generations 4 with dye in the black so high.
Months before Wilhelm got the bad results with Fotonic on matt
Lyson papers we already had that problem, Lysonic E was no cure
as the red was really bad in colour and fading of the cmY inks
still happened, a short experience with Van Son UV dyes was as
bad. The next step was Staedtler's pigment ink but that had the
small gamut of the Roland, Mutoh etc pigment inks, not what I
wanted. Things became a lot better with Generations 4 despite the
fading (to some extent) of the black and the Lm. No gloss
printing done here so far. Epson Archival pigment had some
advantages but also some nasty effects so no reason to abandon
Generations or buy a 9500. With the arrival of Ultrachrome and
the clones there could be a reason to switch colour inks again.
I've received MIS 7600 brand together with the Ultratones that
are already in one 9000. But there are repeat orders that have to
be done with Generations.

The test you describe here has too many flaws. John Nollendorfs
of Lincoln inks (Wide Spectrum) has written me that humidity
during the life of a dye print is an important factor in fading
(and so part of the Wilhelm test) but also that he and Henry
Wilhelm suspect that humidity at that time of printing itself has
an influence on fade properties later on. All in all there are
too many conditions that have to be controlled when printing dyes
that one could say they can be nice in real test conditions but
not reliable for normal use. That is if they have to last. If
your experience is that the prints fade then there's evidence
enough, especially when it is based on the quantity of prints
that you have made.

Ernst

Ernst - I'm a big fan of Lincoln inks which I use on a gelatin paper - 
no fading yet but I've only had them for 12 months. From you email, is 
John now saying that he doubts if dyes can be useful? Emaikls I've had 
from him in the past suggest that dyes are still the best inks for a 
wide colour gamut if you can accept the 15-25 year lifespan.

Julian,

No he didn't say so. There is however a fluctuation in the
results that are hard to explain (same printer, same paper, same
settings) other than that conditions at the printing time must
have had an influence. His numbers have always been on the safe
side but he also has made it very clear that the paper has to be
compatible, like the paper you are using. His inks are based on
Ilford Archiva dye inks and when you check the Ilford site you
will see similar figures. Lincoln inks never had a list of papers
as long as Lyson shows on their fade result pages and the numbers
are easy to interprete, Lyson's numbers are not, the printer
types are mentioned but not whether they are CMYK or CcMmYK and
more like that.

It is more my conclusion that if you think about fading rates
like quoted for the Ultrachromes then you have to take much more
precautions with dyes like the right paper choice to get even
near those numbers. "That is if they have to last" was in my
message. So I just don't believe that dyes even desaturated ones
like in the SG ink can be printed on mat coated papers and get
near the 12 years quoted for the gloss. But with the fluctuations
in the results it could be that it works (so far) for someone and
not for someone else, it could work today and not a week later.
That makes printing dyes on mat coated paper unpredictable.

On uncoated rag paper there's experience with Iris and Epson CMYK
prints that indicate a longer life. The museum conservator I do
some work for hates them by the way as they are so delicate in
handling. Water being the greatest threat.

There have been messages here about an extra treatment for matt
coated papers that will give dye prints a much better life. The
Bockingford paper, FutureWales news that was on this list a few
months ago. I'm sceptic. If it is true it would be wonderful news
but I have my doubts.
When it was discussed I immediately printed with Epson dye ink a
piece of plain Bockingford aquarel paper that you can get in any
art supply store, it has to be said that it didn't print as bad
as I expected for a non inkjet paper. Next to that I printed a
piece of Hahnemuhle Aquarel inkjet paper. Both are in an eastside
window at an inch off the glass. The Bockingford did win like
more uncoated but well sized (PVA, gelatine)aquarel papers will
do with dye inks. Image quality is however lower than on inkjet
coated stock. At the time of that news I wrote that I was curious
how the treated inkjet coated and non inkjet Bockingford
compared, that test hasn't been done. I'm a sceptic.

Ernst

One of the reasons I respect John is that he is really upfront with his fade
data. Even Ilford are abit naughty in their website data. Their most
expensive printer is quoted as having the best fade results but in quad mode
only! You really need to interrogate this kind of data closely!

Hi Ernst

Wow, really? I was always led to believe, by Lyson's tech dept 
included, that matte papers like their Standard Fine Art was the wya 
to go. Hmmm....

Yes, certainly humidity can play a big factor - the only thing is
that 
I live in Southern California where the humidity is very low. So at 
time of printing, humidity was almost invariably always low.

.................

Nick - dyes work best on the gelatin-type papers. I was discussing this with
Ernst earlier and i commented that one of the reasons I have good results
with the lincoln inks is that Barcelona has a fairly high humidity (and
heat!) so the gelatin papers are probably 'pre swollen' to an extent.

I'm always amazed at how this list can ask really interesting questions when

John and Henry suspect that it is possible that gelatine coated
papers accept the ink faster when the gelatine is already a bit
presoaked by  humidity, it isn't good when magenta and cyan are
together in an oxygen loaded environment like on top of the
coating, so humidity is a good thing at that moment.

When the inks are in the gelatine coating then humidity isn't a
good thing in the long run as the magenta and the cyan ink then
stay in contact with one another and the same process continues
but at a slower rate. Ilford Archiva inks more or less and with
gelatine coated papers. Don't think that this represents your
printing but it shows that it isn't simple to predict what will
work out best. Pigment inks seem to be more stable under whatever
circumstances on whatever paper.

On the colorsync list from time to time the issue of "what is the
best ink for proofing" is discussed. One of the things mentioned
is that dye ink targets never give a stable spectro reading in
time. The colour changes not only by the fading in the long run
(which isn't an important issue in proofing) but the colour isn't
stable after 24 hours like most pigment inks will be. Another
symptom that it is more complicated than we think.
