What is offset printing?

Offset printing is a method of mass-production printing in which digital book files are converted into film negatives that are used to etch the pages of a book into custom metal plates. After ink is added to the plates, large rollers pick up the ink from the plates and then transfer it to paper. Offset printing is commonly used in traditional publishing, allowing authors to print their books in bulk. Typically we use Print-On-Demand (POD) fulfillment, where books are printed one at a time after each book order is placed.
