Digital BW, The Print

Jimbo, The color of the light is quite important in silver printing. Multi
contrast papers react quite differently to different color light. Graded
paper also can change based on color of negative; see pyro. The addition of
multi contrast printing a while back in silver gelatin printing was a great
advantage to photographers that chose to alter local contrast in the
darkroom during printing rather than through the use of colored filters
while shooting and film and developer combinations during process. Green
light produces flat prints, while blue increases contrast. ( Magenta (high)
and Yellow (low) in opposite terms of light).

Eric,
Right now lets have my comments be thoughts only as I'm not far enough along
with the "Green" negs but I'm in it now up to my neck that's for sure..
I feel the green is significant only in respect to how it functions with UV
light.. conventional negs work with visible light so shades of black are
probably just fine I would think..
I have two printers I'm playing with... an Epson 4800 and a Canon IPF 9000
but presently I'm mostly focused on the 4800.. What I'm noticing is that the
greens seem to have a better level of shaded transparency then does just
black inks.. Probably due to the pigments used.. I started out with just
Black and cyan on the 4800 but since have really changed the recipe.. I'm
using all three blacks both cyan's and yellow in a B&W environment in Studio
Print using only 6 shades in the 8 shade environment.. I have yellow as
shade 3 and have adjusted the densities of the cyan's to get me to what is a
shade of green that blends visually quite well with the blacks.. I'm still
tinkering with the mix but think I'm about as far as I should go with this
concept ..so I need to try it and see what I get.. The negs look quite good
to my inexperienced eye. So we'll see. Anyway for conventional silver prints
using visible light as a the light source I don't think green would matter..
but it would be easy to validate that simply by making a neg both ways and
see what results came out the other end.
