PDF print quality

Check out your .CTB (or .STB?) pen-control settings in the plot dialog. If you have not applied any, you'll get color output by default. If the PDF-making driver is set to B/W or grayscale, you'll get washed-out B/W or gray images wherever you've used light colors.

PDF Export

I missed the key word "export" in your post, sorry.
I just tried the Export, and I didn't see where I had control over color vs black-white output. My output was a color PDF file. From there, if I wanted B/W, I would probably set my printer driver to change color to b/w, usually this is possible. If there is a better way to control Export settings that don't appear on the dialog, I hope someone will come here and say so! :shock:

My previous response assumed you were using PLOT, not the export process. Using plot, you can go to (probably any) Windows-configured printer driver, and have more control over colors and pens via the plot dialog. I suggest PDF995 or Adobe Acrobat itself for that.
