Description

TECHNICAL FIELD

[0001] The utility model relates to printing technical field, especially a clamp and printing equipment. BACKGROUND

[0002] With the development of printing technology and the improvement of people's aesthetic demand, the appearance design of books has become an important part of the publishing industry. The traditional book decoration method mainly focuses on the beautification of the cover and the illustration, while the decoration of the book mouth (the side opposite to the spine) is relatively less. In order to improve the overall aesthetic feeling and collection value of books, people begin to explore the method of adding decorative patterns at the book mouth.

[0003] The direct jet hidden book mouth process emerges as the times require, which combines digital direct jet technology with hidden book mouth drawing in bookbinding, bringing a new visual experience to the appearance design of books. This process prints patterns or texts on the book mouth (i.e. the cutting edge part of the book) through digital direct jet technology, and uses special processing methods to make these patterns or texts invisible under normal conditions, and only appear under certain conditions (such as book bending). This process not only improves the appearance and artistry of books, but also provides new possibilities for book anti-counterfeiting and personalized customization.

[0004] However, in the actual direct jet hidden book mouth process, in order to make the patterns or texts on the book mouth appear under certain conditions, the book needs to be kept in a curved state during the printing process so that the book mouth can be fully unfolded. However, the existing book bending tool has many problems in the process of use, such as complex operation, unstable book bending effect, and large damage to the book, etc. These problems seriously affect the implementation efficiency of the process and the overall quality of the book.
