The lithographic DVD printing process involves making a metal printing plate which is curved around a roller. The basic principle at work with this process is that printing ink and water do not mix. The printing plate surface is treated in some areas so that it attracts ink, the remaining areas are treated to attract water and not ink.

The result is a printing plate that can be introduced to ink which only adheres to it where required. The ink on the printing plate is transferred or “offset” to another roller which has a rubber blanket wrapped around it. The rubber blanket roller applies the ink to the DVD which is held firmly in place in a metal jig on the machine bed.
