The Digital Duplicator is also known as the Copy Printer; the print process (stencil printing technology) is a wet print process more similar to the lithography/offset printing process.  In stencil printing, the images are reproduced with ink that is pushed through the microscopic holes in the master.  The Digital Duplicator process is where the image of the content we want to produce is placed on the master, which is then covered in ink and used for printing.
