What is Smyth-Sewn Binding?<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Smyth-sewn binding gets its name from David McConnell Smyth, inventor of one of the first book-sewing machines in 1868. This binding method involves sewing groups of pages, called signatures, together with thread. The sewn signatures are then attached securely to the hardcover casing, creating a highly durable and high-quality book. Smyth-sewn binding is regarded as the premium standard in offset printing, especially for hardcover books.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
