How to Download and Use an AutoCAD Monochrome CTB File

A Monochrome CTB file is a plot style table for AutoCAD that forces all plotted objects to print in black (or a single color), regardless of their on-screen color. This is commonly used for construction drawings, plans, and any deliverable that must be printed in true black-and-white. This article explains what a Monochrome CTB is, why and when to use it, where to get one, and how to install and apply it in AutoCAD.

Troubleshooting Tips

  • If the monochrome CTB file is not listed in the Plot Style Manager, ensure that it is located in a directory that AutoCAD can access.
  • If the drawing is not plotting in monochrome, check that the monochrome CTB file is selected in the Plot dialog and that the plot settings are configured correctly.

By following these steps, you should be able to download, install, and use a monochrome CTB file in AutoCAD to print your drawings in black and white.

Applying Monochrome CTB consistently

  • Set as default in templates: Open your drawing template (.dwt), set Monochrome.ctb in the Page Setup Manager for relevant layouts, then save the template.
  • Use Page Setups: Create and save page setups that use Monochrome.ctb and import those setups into other drawings.
  • Batch plotting: When publishing multiple drawings, ensure Page Setups or the Plot dialog specify Monochrome.ctb to maintain consistency.

3. Trusted third-party CAD resource websites
