Alternative Downloads for Custom CTB Files

Once you have downloaded or created your monochrome.ctb file, you must place it in the specific directory where AutoCAD looks for plot styles.

AutoCAD offers two primary plot style systems: CTB (Color-Dependent) and STB (Named Plot Styles). Most users and firms in the US and Canada use CTB files because of their simplicity. They are based directly on the 256 standard AutoCAD Color Index (ACI) colors. STB files are more flexible but complex, allowing you to assign plot styles by layer or object name, regardless of color.
