The clean(est) way of tracing is your recreating the artwork with the Pen Tool, using the image as an underlying locked object.
Uploading an image (using the Camera icon to avoid queueing) might help the helpers.
You can try uploading your art to this website: http://vectormagic.com/home Like any tracing or vectorization process, certain elements/shapes/etc. work better than others. If you are in need of near perfection results, there is only one way to accomplish this... recreate the art.
It's funny that about the time I decide to get on one of these forums, I figure something out. Redrawing this artwork (actually tracing with the pen tool) is really out of the question as we're talking major freehand ink drawing. I've thought about that, but doubt my client would pay for that sort of effort. ANYWAY... I believe I found the tool hiddin in Illustrator CS -- the "Live Trace" feature, which works pretty much like good ol' Streamline, but I'm still monkeying with it. I think I'm on the right track now.
Appreciate any tips anyone can offer regarding this feature as well as colorizing line work once it's traced (I reckon with "Live Paint" feature). Working on this but having issues.
Take that, Jason.
You will probably need some cleanup after Live Tracing; among the options are Object>Pat>Simplify and Add Anchor Points. If you post an image, you will get suggestions.
There are a few ways of colourizing; the neatest one is the use of closed paths. You may colour both fill and stroke (or use fill/no stroke or stroke/no fill).
