Perhaps 92 for black and 290 for total would be more suitable for the stock

Geza,
There is usually more than one thing that can cause a color reproduction to
look bad. The black point target values or total ink in the shadows can be
one factor that contributes to a bad color reproduction. However, if you get
the tone reproduction (the right highlights, midtones and shadows) adjusted
to the be correct for that image and paper and on that press, you will find
that to be a big help in making the image print better.
That means you have to examine the printed image and then determine how you
would need to adjust the highlights, midtones and shadows to make the image
print better. Once you determine that then you create color separations with
those new highlight, midtone and shadow characteristics. In your case it
sounds like you need to start by reduce your midtones so you can then
increase the density of you ink without ruining the image because of too
much dot gain. By how much? You need to run a few test to see. But that is
just a guess based on your post. I am sure there are a few other factors.
Good Luck
Jim Rich
