Offset printing, which has been around for a long, long time (since the mid 1870s), is based on the proposition that oil and water do not mix, and that if you draw on a custom printing plate with a greasy substance like ink, and then flood the non-image area with water (in a precise ink/water balance), ink will adhere to the image area and be repelled by the water in the non-image area. The ink can then be printed on a press blanket and from the blanket to a paper (or other) substrate.
