About copy books and offset books

The copy book is copied with the copier
of the convenience store and made.
When circulation is a little, it is convenient
because the deadline can be postponed to the very limit.
It is improper in the book with a lot of pages
because there is hand work of stopping it with the stapler.

The offset book is made by requesting it to the print shop.
You may make it to an off book when
there is a lot of number of copies because the unit price becomes cheap
if there is a lot of circulation.
Because the company binds a book, finish is beautiful.
However, you should observe the deadline strictly.
