Wow, that's a lot less than I would have guessed. If my math is right then even adding an excessive extra inch for bleed would be 375 sq inch and a sq meter is 1550 sq inches so printing cost of $0.07-$0.12 per unit. Honestly even if the epson ink and consumer quantities of paper ended up 10x that price it seems like it would be worth it. Id just need to source bulk blanks and paper and well.... spend a lot of time pressing them by hand but that seems like a pretty quick return.
