Hi Everyone -

Can immersion silver be used as an etch resistant? I currently use
Ferric Chloride.

The reason I ask is that I flood my boards with copper, and the toner
is a bit starved trying to print large blocks of solid black. If I used
negative printing and a etch-resistant plating, this problem would go
away (I hope)!

Thanks
