Use 100% K for the text color when you desire 100% K text. If in doubt, use the color editor to check your text.
The screen shot is from Acrobat showing 100% K text. The "sampling cursor" in Acrobat is highlighted in light yellow.
Take care, Mike
Edit to add...there is also a Pantone color showing in this screen shot because I was reusing a saved sample file for someone else...
