Generally the consideration for your print job depends on a few factors. If you require large quantity printing, offset printing provides better cost advantages compared to digital printing. In fact, the more you print, the cheaper the price on a per piece basis. This is because most of the sunk cost is in the setup fee of the “plate” used in offset printing, this one-off sunk cost drops on a per piece basis when averaged out over a large number of prints from the same plate.
Offset printing also allows a large variety of different paper types to be used with different finishes depending on your creative needs.
For customers who are particular about the quality of the colours in your print job, offset printing offers a more superior colour output due to the differences in printing technology.
