Homebrew PCBs

result of steadtler RED 1:1 mixed with denatured alcohol on alu can be 
seen at:
<http://stud4.tuwien.ac.at/~e0225977/pub/alu_staedtler.jpg>

the X you see are textmode X,
on the left i printed a solid red vertical stripe in a second run.

I'm not sure how to interpret it, any ideas?

I used the yellow head, one or more jets are clogged.

Should i use the black head? has more nozzles and all are clear says the 
test head print.

it is a 720DPI printer, and a 1200DPI scan.

looking forward to discussion.
