So we back. Before we left, I printed same image with MIS UT inks on tree
different papers (Tetenal, Forte, EAM) with same settings for printer plus
one with Epson OEM black ink only on EAM paper. Than I taped them on window
facing south west side. I taped them that half of image was exposed to Sun
and other was hidden. It was very hot and sharp sun for the past two weeks.
This was kind of simple heavy fading test.
So after two weeks of direct sun exposing I have all four prints here in
front of me. Epson OEM inks on EAM are terrible! Black is completely
brownish. And even not that is very light brownish almost gone.
First, just comparing yellowing of paper. Epson EAM yellowed the most, but
it is not very visible when you compare with non exposed part of image as
paper is not extremely white in its own. Comparing it with real white paper
give you feeling how much yellow is it.
Tetenal and Forte are very very close with Tetenal be little more yellow
than Forte, which is the best. It is important to say that yellowing is
visible but only in very good light. I did comparison outside in bright
cloudy day around lunch time. Yellowing all papers is very close to each
other, with EAM being the worst and Tetenal and Forte very close to each
other.
MIS UT inks have no visible fading on any paper. If I do not count
yellowing of the paper and try to compare changes of inks on the border
between sun exposed part to hidden part, I can not see any difference.
Conclusion, If I have paper which do not yellow (probably paper which do
not contains whiteners) I woudn't observe any changing in pictures. Maybe
Hahnemuhle PhotoRag is the one. To be tested this week, hopefully.
