I have a text box with both Black and one other color mixed in the paragraph. I also have other objects on the drawing, some black, some color. I'm trying to export this as a TIFF to my commercial printer. They requested 2 TIFF's, one with only the black on it and one with only the color on it, along with registration marks for alignment. Is there any way of exporting only objects that are black (or any particular color)? Is there another way to "skin this cat"?
