Force the use of 100% black ink
You can force Command WorkStation to use black ink only to reproduce text and line diagrams that were defined as 100% black in the graphics program.
When pure black is converted to the CMYK color space of the printer, small amounts of CMY inks can involuntarily be added, which produces a “dirty” looking black.
