Hi! a wesite that I want to use to get some black and white prints done says

" It is important to check your files feature a full range of tones and that blacks really are 100% K despite how they appear on the screen. If your blacks are only 90% K your prints will look flat. "

So I'm using CS3 how do I know if my blacks are 100% K.

Many thanks
