Skating on the Photoshop sliders

Recently a writer to one of the DTP/Publishing lists I subscribe to was having trouble coping with instructions from a printer that detailed their pic specs as no less than 5% highlight dot, 80% max shadow, and midtones of 35 to 40%. The printer then added that this particular press might want the midtones down by another 10 or 15%.

That seems like a lot of old newspaper presses I know. Though, on second thoughts, they'd be hard pressed to hold a 4% highlight dot. My instructions on one paper were to drag both sliders in Photoshop in significantly, then drag the gamma slider across most of the way: no point in talking numbers, this was like engraving with a chainsaw -- provided you could hardly see anything on screen, there was a chance the final result would be fine.

The really amazing thing is that the final results were quite good.
