Nij

I'm not exactly sure I was testing the overprinting in the context you are
referring to, but I did overprint my "blacks" with good results on an 1160
with EAM. Perfect registration with a VISIBLE doubling of density. But in my
tests I really limited the overprinting to about 95-100% tonal densities,
through masking.

I still recommend others try this for those images that really demand a deep
black, especially broad areas which contain few details.

My limited testing (3-4 prints; not enough to be truly meaningful) showed
this to be a very viable technique, at least in the way I applied it, though
it is quite a bit more time and ink consuming, so not practical for everyday
work.
