Thanks guys!

I did the test I referred to earlier. I'm going to attempt to post it here. (haven't posted any attachments yet). I ran it on the Metalgraph Plus. I used color mapping in the driver to set up 10 squares-1/2 x 1/2 and ran them at the associated speeds and power at 400dpi and 600dpi. The results are pretty evident that on my machine I got a better result with this particular material at 600dpi and slower speeds, higher power.
