Litho-Offset Printing offsets ink from metal plates to a rubber blanket (cylinder) to the paper. Of course before the metal plate is produced, the artwork will be transferred to a CMYK film output before being transferred to the metal plates which usually is usually made from aluminium. This is the most common printing process today; it can be thought of as the workhorse of the industry. Most books, magazines or newspapers are printed using this process. These are for large quantities and longer turn-around time.
