adjusting histogram for printing

| Hi,
I have loads of pictures for which I have to adjust the histogram as my
printing factory told me that the range of the histogram should be
between 10% and 90%. What does that mean in Photoshop CS (8.0)? We tried
the shadow/highlight dialogue: black clip and white clip but the
histogram still shows dots between 0% and 100% and it shows white lines
in between and is lower then the original one.
Thanks for your help,
Achim

| that is weird because I was told you should never move the white and black
points or you lose data from both highlight and shadow areas. So unless you
want less detail in your images I don't get it.

Open 'Levels' and move the two sliders underneath 'Output Levels'
inwards so that the output levels become 25 and 230.
