Hi everyone,

I wonder if someone knows what kind of tonal scale (range) one can expect with gum printing when using a certain number of exposure for the same print???

I assume density will build up, thus increasing the range between the white of the paper and the darkest areas. I suspect also that these multiple exposure are not linearly additive meaning that if I get a density of say 1.0 somewhere on the first exposure I wont get 2.0 with the next exposure.
