RE: Colorized Negs for Gum
In fact many black ink have a good uv blocking effect. but when we make
digital negative we should remind that we work with transparency which do
not absorb ink as paper does. So using the most UV blocking combination of
ink which at the same lay down less ink is a good thing to find. As at high
inkinng we may loose reslotion due to the absorption time.

Hi,
as I understand it, colorized negatives are mainly used for the uv
blocking effect of certain inks, especially when using processes with long
tonal range (palladium...)? With gum printing (short range) you will
normally get enough uv blocking with grayscale negatives (printed with
black only or with all inks mixing the grayscale) from almost any inkjet
printer.

Hi all,
If anyone is printing digital negative for gum, are you using colourized negs?
If so can you tell me what negs, printer, color combination, print
setting your using?
Thanks
Jacek
