The production of these books as pictured requires one of our two automatic case makers. The book has been perfect bound before “casing in.” We had an additional score 3/4 of an inch on the back cover from the spine. We could not case it in on our casing in machine, the book is much thinner than the hard stiff spine. In this situation we took the finished perfect bound book, full surface glue the inside the front of the hardback case and then we formed a gusset pocket and glued it full surface, inside the back, cover of the case. We then inserted a product of red folder. When closed it looks like a hardback case bound book. It is reasonably durable functionable for something like this please call us.
