as well as book trimming and basically any and all other operations that occur after the book got printed as a stack of pages from an industrial laser printer.
Does this involve some sort of manual work? Are the machines involved expensive to buy? Are there large maintenance expenses for keeping these machines running after they are bought (as in the case with industrial laser printers) or do they usually just work without problems?
Is it important for the machines to work with books of a fixed length or can we assemble batches of books with 200 pages and 300 pages in the same production line without any expensive adjustments? Let’s assume fixed page size for all batches.
Are any of the supplies used, e.g. maybe glue, expensive? Or is the production cost almost entirely dependent on the cost of machine time?
Also, are there any “modern” non-industrial but sufficiently productive methods of book assembly? E.g. are there industrially produced kits that could be used to bind books using relatively primitive tools by trading off labor for capital? Could you let’s say bind a book in 30 minutes of work using some such “low wage man’s binding” method?
