It was very hard to remove the dykem between DIP pads and the plotter scratch shows up as low resolution lines with dykem between them.  The pens worked better... for me anyway.  Good luck.

Thanks.

I had thought I might experience 'drag' causing the plot(scratch) to
be erratic so I had decided to get an etch resist pen in ready for
when it comes, I found that I can buy (WHS uk) sharpie's but only in
blue or black, or a twin pack of black and red.

I bought a blue and a black.

I have seen advertised that a staedtler lumocolor (permanent) will
work, but could not find one.

....Just done a quick test, black worked better than blue but looked
like it was a thinne coating(?) and my cheapo 4 for a £/$ cd pens
worked just as well!
