My 100% black swatch is showing as gray in the swatches palette. It won't let me alter the swatch, although it is showing 0% C, M, Y, and 100% K so I shouldn't have to. Everything in my book is printing gray including the crop marks. I've gotten new printer cartridges and checked every possible area for color I can think of, to make sure no tints are set to below 100%. I even checked "print text as black" in the printer set-up box. Any ideas? I'm desperate.
