>I need to print say blue at 0.4mm and green at 0.15mm.
Gary,
using color-based or named plot style tables you can have every color
(or even every object) plot exactly the way you want. This not only
includes plot color and linewidth but also many additional plot
settings. Just create your own plot style table (color-based in your
case), then edit it to make blue print at 0.4mm black, green at 0.15mm
black and so on.
