I did a quick test of Johnson’s Baby
Oil with a sheet of Costco Kirkland Glossy ink jet paper (aka Ilford Gallerie Premium
Glossy Inkjet paper) and a digital negative printed on Clear Print Vellum.
The Costco paper was printed with an Epson
1280 printer with OEM dye inks and the Clear Print Vellum was printed with an Epson
2200 using OEM Ultrachrome inks. Neither paper showed any ink bleeding.
The Costco paper did not turn translucent
except at the edges of the paper. I then peeled the backing off and re-immersed
the paper in baby oil. It did turn translucent then, however I had a difficult
time peeling the RC backing evenly and the peeled paper looked splotchy.
For the record the Costco paper base (without
oiling and peeling) has an ortho log density of 0.73. Quite suitable for making
negatives for silver gelatin printing, however the UV density of the unoiled Costco
paper base was 2.90, not suitable for actinic processes.
The un-oiled UV log density of the Clear
Print Vellum is 0.70 and the ortho density read 0.18. I tested the Clear Print
vellum last year for digital negatives (using BL tubes) and found that the
printing time to be extremely long to get a faint image for traditional
cyanotype. Perhaps I will retest it soon with my new NuArc 26K to see if it
works any better.
The oiled Clear Print vellum is drying now
so I can’t report anything about the performance of it with Johnson’s
Baby Oil. Maybe next week.
I may test the Epson Enhanced Matt paper to
get an idea of how it works.
P.S. MIS traditionally doesn’t reply
to e-mails so if you need product information call them.

Details - Dyes versus Pigments?
And on that note, I'll
make another attempt to steer back to the original question that started this
thread: is there an advantage of using dye inks over pigment inks
for paper negatives? I'd test it myself, but while the pigment ink cartridges
on the Epson 7600 I have recently acquired are mostly full, the yellow is empty
and God forbid Epson would allow me to print anything without yellow.
Ahh, but if some kind soul would print a postage-sized print with Ultrachrome
inks and smear a little baby oil on it to see what happens - well, I would be

I think bleeding may
depend more on the ink than on oil vs wax. I've
used exclusively dye inks and have had no problem with bleeding with
either oil or wax.
