Hi Lee !
David Tobie told You one way about how to do it.
Here are the background informations and perhaps another way:
Any normal printer which print on paper cannot print for backlit in
comparable quality because of following facts:
The light falling on the print will be filtered by the colors on the
paper, reflected by the paper and then on the way back filtered a second
time. This effect makes the right density of colors on paper-prints. For
example print Your picture on a paper an with the same setttings on a
clear film. Then put the clear-film in contact on the same blank paper You
used for the print and both, the paper-print and the film-paper sandwich
look nearly the same. Put the film on a display-light it will look much to
bright with low contrast.
In the classic photography the clear- and trans-display-film emulsions
have twice as much silver and color and have to be developed three times
longer than the paper emulsions to get the same brilliant look like the
paper-prints.
Do You know DayNight-posters? These posters are printed on special double
coated paper or white foil and mounted in a backlight display. At day the
sunlight will be reflected normally by the paper. At night the poster will
be illuminated from the display. To get the right brilliance for the
colors in display mode the same picture, only in black&white, is printed
at the backside of the poster.
Perhaps this may be a way to get brilliant prints by mounting two backlit
materials, one with the color-picture, one with the black&white, face to
face together. Test it !
