Interesting article, thanks for that may get me in the mood for printing PCB.
I thought of a modifacation to the document as i have had a lot of problems removing ink cartridge PCB so it doesn't confuse the printer. Instead you can purchace refill cartridges which i buy from
www.inkbank.com.au and fill only with one colour.
To improve resolution Inkbank also sell high res pigment inks as well.
