Reply To: Placing Word Doc Text as CMYK

After the text is placed in InDesign, Swatches->Add Unnamed Colors. There may be an RGB black in the Swatches Palette. Delete and replace with the Black swatch. Window->Output->Separations Preview->Uncheck Black to see if there is any built black. Your black text should be 100% Black (No Cyan, Magenta, Yellow).

The fact that your printer is asking for this is an indication that they are a good printer and care how your work looks!
