Homebrew PCBs

food coloring:
in the initial posts here quite a while ago there is stated food coloring works.
i have none at home (see no reason for coloring the food...).
i maybe will get one if i find out where it is sold.

to the pigmens:
i once used "pigmented ink" to refill the cartridge and it also worked.
(i assume they were small enough)

regards
stefan
