As discussed earlier, the production methods and how the printing actually occurs makes up a large proportion of the difference between the two choices. Offset printing is far more mechanical with large machines, big rolls of paper or high production, and a heavy volume of output on each run. Digital printing focuses far more on high quality detail for smaller jobs. It works extremely well for highly customized jobs that have varying degrees of difference from one output to the next as well. A good example would be a limited run of art prints of the same image but in different variations to create a distinction between premium versions and far more common copies for lower pricing.
