Part 8: Advanced Customization – Screening & Dithering
A great Monochrome CTB doesn't just turn everything black; it creates depth.
-
Screening (Fade): This reduces the ink density. For example, setting Screening to
50%on Color 8 will print as a light gray. Use this for:- Property lines
- Topography
- Referenced drawings (Xrefs)
- Notes that should not compete with geometry
-
Dithering: This scatters dots to simulate shades of gray. Turn this ON for screened colors (to make gray look smooth). Turn it OFF for solid black lines to keep them razor-sharp.
Pro Tip: Create two CTBs: Monochrome_100.ctb (for final issue, no screening) and Monochrome_50.ctb (for working drawings, where xrefs are screened to 50%).
Why Use a Monochrome CTB?
Even if you want a black-and-white drawing, simply switching your printer settings to "Grayscale" often isn't enough.
- True Black: A Grayscale setting might try to print Yellow as a light shade of grey. A Monochrome CTB forces Yellow (and all other colors) to print as 100% pure black K-ink.
- Line Weights: Most standard Monochrome CTB files are configured to assign line weights based on color. For example:
- Colors 1-9 (Standard colors) might print with varying widths (heavy for walls, light for details).
- Colors 250-255 (Greys) might print as "Screened" (dotted or lighter black) for shading.
