I'm trying to perform an image-trace on a bitmap artwork. The vector result will then be cut into glass, and I need to have exactly 60 colors, since we only have 60 colors of glass.
Is there a way to set up Illustrator to image-trace a limited palette of 60 colors? I've found the slider in CS6 that ranges from 2-30, but is there a way to force it to go over that?
You can simply create a color group of your 60 colors and set the Palette To Document Library then pick your 60-color color group.
You can always use
Edit > Edit Colors > Recolor Artwork after tracing to reduce colors if needed. Recolor Artwork is often a better option than trying to limit the tracing.
