Staedtler makes an ink refill, 485 23sar-9 ink. There was a post
around 6 years ago recommending it for plotting to PCB use:
http://eeshop.unl.edu/pen.txt(Carl Quies, who suggested it, does not seem to be around anymore on
the net, or in Missisauga (near Toronto) where he used to be)
The Staedtler support person in Canada told me that "I have heard of
people using this ink for different things. I honestly do not know
about circuit boards. Officially it is used for glossy plot surfaces."
The guy who recommended it for PCB's recommended using a plotting pen
with a grooved tungsten-carbide ball. If I can find a suitable
drafting or technical pen I will try this ink out, a bottle is only $7
Can.
