Digital Business Cards

If they want to print double-sided 10000 menus glossy paper they use digital printing for it? is it fast enough and how much their costs of ink that the wholesale price? they also use paper rolls or sheets for this?

For the volume they would most like to use a printing press. Most use a paper roll and cut to size.
I'm not sure what the cost would be ink, however, when I look at quantities of 10,000, I pay about $ 0.04 per unit.

No, if you need to print 10000pcs you should use a professional printing machine, it is faster than the digital printer, digital printer can take weeks of time to print all professionals, but the machine n 'needs only about 3-5days.I would recommend the automatic equipment printing of our business, it will cost more than USD8000 if you need to print parts of frequency, or we can provide the print service, it will only cost you $ 0.03/pc whether to print 10000pcs We are a professional printing service and manufacturer of PVC cards with multiple sets of automatic processing machine.Just contact me if you any interesting.My email: leeou1990@hotmail.com
