Old school book printing

Printing a Book, Old School from Armin Vit on Vimeo.

This is a facinating video of how books were made, or maybe they are mostly still made this way? Even more impressive is the thought that newspapers did this process every day for each new edition.
Another thought I had was if you went back in time to say pre printing press times, would you be able to describe how books are made? Would you be able to describe anything beyond a simple screw press? How to bind them by hand? I certainly couldn't have described how to print the pages in the manner described in the film, let alone how exactly an digital printer does it today. Looking deeper I was surprised to find that digital printing accounts for only 9% of printing. The wikipedia page on modern printing is interesting reading as well.
