I am trying to get a monograph of a portfolio printed. All the options either require a huge upfront cost for offset printing or a cost per unit that's too high to sell the book if done with an online printer plus poor quality there. I am considering investing in a printer and K7 Carbon ink set to do the printing myself. Before I take this path, I need to have some idea of the capacity of the K7 set. Does anybody have a ballpark idea of how many 8x10 prints on average can be made from one K7 set of 125ml bottles? Thanks.
