Homebrew PCBs

Hi All,
I painted copper clad PCB with different ink colors,
it seems most etch resistant is yellow  and second is
magenta. I also applied combinations of 3 colors to
generate black and black blue. The losers are black
and blue. The combination of three colors is also etch
(Ferric Chloride) resistant. I will upload the scanned
image of the board Files > Epson_inkjet_Volkan folder
Most probably I will use magenta+yellow combination
since yellow is not so easy to see on copper.
