Is there a way to convert 4-Color Blacks(Rich Blacks) to 100% Black? For example today I got a file that was CMYK 4 Color however the blacks in the PDF file were not 100% Black is there a way to convert the 4 Color Blacks to 100% black in Acrobat? I don't want the whole PDF to be Greyscale. I still want the color but I want to specifically target the 4 color blacks and turn them to 100% black. Can this be done? I am using Acrobat 8.
