Dear Harry,
This format was fairly common in the nineteenth century, especially after the introduction of lithography made it possible to recreate the 'look' of a manuscript page. Ulrike Stark has written a bit on this (see Empire of Books) as has Graham Shaw ("The Introduction of Lithography and its Impact on Book Design in India"). Shaw characterizes lithography as making possible the "mass production" of manuscripts. I think there are some other things to be said about that but certainly some communities did see lithography as a way to mass produce copies of sectarian works in the form with which they were familiar.
All best,
Tyler
