Can you show the original image you are trying to trace?
Often for this kind of images the master image is a black-and-white drawing, saved as a 1-bit-image. The CS6-tracing doesn't do well with this kind of bitmaps. Better to scale it down a little (or resample), don't sharpen too much (if at all) and then have a grayscale image to trace.
You cannot get the live-trace-module into CS6.
I can't show the original as it is a HUGE file, 10000 pixels wide. I scan as high as my scanner will go. And that 10000 is shrunk down already so as not to exhaust my RAM. Below is a smaller version, but yes it is a b/w drawing but on a colour scan. It's been treated using Levels in Photoshop to remove the grey/blue colour of the paper, but nothing else.
I can see round the edges of the black in Photoshop that there are bits of colour, mainly reds/yellows. What do you think I need to do to it to help it trace better?
Actually, I'll throw in my Image Trace settings too, so people can see what settings I'm currenty trying... I got the Threshold directly from Comic Art in CS5.5.

A small portion of that huge file would suffice.
Your scaled down image looks like you raised the contrast to make it very hard. Image trace is better at guessing than it is at tracing images that leave no doubt.
10000 Pixels sounds like very huge. Scale it down, don't sharpen and leave it as greyscale. That way you can set a very high "Paths" setting without getting every singe pixel traced.
Do I use the original scan, but in greyscale? As in, without playing with the Levels/Contrast.
Just converting the file to greyscale won't help. ou need to resample it. There needs to be anti-aliasing around the edges or even a silght blur.
Got round to trying it out today, and my new trace is better than the one I first showed. It's a lot closer to the CS5 trace, so it's certainly the way I need to go with my scans now. Thanks!
