Oblique mouth making process

Normal > As the society progresses, people's consumption levels and aesthetic standards are constantly improving. In recent years, bookbinding design and production have become more and more important to the public. Special printing, special paper, special technology, special-shaped format, abound.

Normal > Because of the close cooperation with the publishing house for many years, our factory designed and developed the first book of oblique mouth in our country. The editorial teachers of the publishing house often go deep into the factory's workshop to design, research, create, and edit manuscripts in the field, using the factory's production workshop as their second studio of creation. At the same time, the factory also actively cooperates to provide the best service. In 2001 , teacher Han Jiping of the Shandong Literature and Art Publishing House proposed the idea of ​​producing skewed books. After repeated trials, we finally succeeded, and we have applied it in the book “The New Commentary on the Particular Culture of the Notes” ( shown in Figure 1 ) . This oblique book design and production is a major innovation in the history of book binding in China. This book has now been collected by the China Printing Museum. The author here talks about the book's production process and points.
