300 DPI equates to 3.33 mils/dot. that makes a 10 mil trace all of 3
dots wides. On a 600 DPI device, that would be 6 dots. 1200 DPI -
12. Of course using a magnifying glass one can clearly see that the
dots aren't exactly round. Its not suprising to me 300 doesn't do it
for fine traces. If it were me, 1200 DPI.
I use an inkjet and then a copier. My printer has 1440 DPI resolution
and the copier is an "analog" device so its resolution is about the
size of the toner particles (probably effectively less). no problem
with 10 mil traces.
