I have looked into arts cow for printing. Most of the boards I have done seem to large for them to be a good price point. I did find one online printer. Mimeo. They were the cheapest I could find for my situation. They print 36"X48" posters. They have a %50 off your first order discount up to $1000. So I ordered two posters with two boards(printed my La Citta, Primordial Soup, La Citta score track, Vinci,and Full Metal Planete) on each. With shipping it came to around $37.00. Making it $9.25 a game board. That was the best price I could find. The paper is a non glossy thin type. Not the best but with Plexiglas over them they look quite elegant and inviting. I had to call them and use their tech support for such large files but overall I was satisfied with what I received. Without the discount it would not be cheap enough.
I don't think I want to know about Brazilian Bootleg versions of my game but I sure like this. So corrugated, so cardboard, dammit, why print such a beautiful board on...
