"Digital printing" means a printing method which includes, but is not limited to, the electrostatic process of transferring ink or toner to a substrate. This process may involve the use of photo imaging plates, photoreceptor drums, or belts which hold an electrostatic charge. "Digital printing" is also defined as a process of transferring ink through a print head directly to a substrate, as is done with ink-jet printers.
"Offset printing" means lithography, flexography, gravure, or letterpress. "Offset printing" involves the process of transferring ink through static or fixed image plates using an impact method of pressing ink into a substrate.
