A question that people seem to have lately is why is some printing more expensive than other printing? I believe that a few things come into play when this is asked.
First thing is that the price may depend on the paper you want to print on. Like the weight, and grain, and size of the paper will or could make the pricing more in printing if the paper you choose to print on is more than the standard piece of paper.
Next could be the size of what you want printed, it could be more expensive if you want to print some thing that is twenty pages rather than something that is ten pages.
Finally the amount of colors that you want printed on your piece. Say you want something printed with ten different colors, that could cost more than printing something with just three different colors.
These are just a couple of things to keep in mind when thinking about print something with a print shop, than rather at home. I say that because if you print at home it is cheaper because you are using cheaper paper, and not getting the best product that you could be getting if you spent a little more money on it.
