Martin,

keep in mind that I am not complaining about "fade" or "warming" overall, 
which we have learned to live with. It's this nasty separation of just the black 
ink going brown and lighter than surrounding tones that makes the whole print 
ready for the trash.

Admittedly, hanging uncoated, unframed prints is supposedly against archival 
procedure and hence really meant as an "edurance test". But with the 
Sundance inks, I have prints left exposed to the elements for over a year and 
they have warmed and (I am sensing) faded a bit, but never separated into 
this solarized look.  And it only took 2 months for it to happen with the PTs.



Didn't you stick a PT print in a window at one point or

Yes I did and still do and took another look today: I don't see the same 
bronzing out I saw in the big prints. The areas of black are small but don't 
seem affected. This was a print from an 1160 made with beta carts of WT-PT 
on EAM and exposed to similar light as the big prints - in fact for much longer. 
They were printed using the piezo plug-in. 

Could there be something else going on? The 7000 prints used sealed 7000 
carts bought from inkjetmall. All of them exhibit the same bronzing out, there is 
no difference from early to later prints. The printer was flushed using flush 
carts also from IJM - everything was done by the book. Do we have a bad 
batch theory here?

Yes.


If the Sel-PT with the FS-K

I think I will need to test that combo immediately and send the PT black carts 
and bottles back to IJM for refund. Too bad; I had high hopes - despite the 
early warnings from Paul - about the PTs. 

Too good to be true, I guess.
