Hi Hellena !
I cannot directly reply to your question
since my HP B9180 uses 8 different Vivera ink cartridges.
I looked at your printer manual on line to read what they say about the
choice of inks combination
you will find info at page 28 /154 of the pdf manual; in England, you are
considered as Zone 2 for the compatibility of cartridges.
If I were you, what i would do would be to make some tests with different
combinations, using the test page functiunalities; see
If you make these tests on your transparent substrate, you will be in
capacity to analyze the way the different inks settle on your film and to
compare the opacity of various combinations.
Before doing these comparisons, do not forget that for producing good
digital negatives on transparent film, you will have to choose probably a glossy
photo surface as the printer media type setting. On my Hp 9180, i use
the following setting : HP advanced paper , Glossy.
I do not know which method of producing diginegs you are using; I use the
PDN system from Mark Nelson and in fact, opacity of black inks is not really an
issue since the calibration tests are founded on UV blocking colored inks and
negatives are "color negatives" ( different colours according to each alt
process)
Hope it may help you,
Bon courage, Hellena,
Cheers from france
