Technical Field

[0001] The invention relates to the field of paper printing indentation processing, and in particular to a paper printing indentation processing technology. Background Art

[0002] Paper printing creasing processing is an important method of post-printing processing. It aims to form grooves or lines at specific positions on paper printed products that are easy to fold, thereby facilitating subsequent folding, forming and other processes.

[0003] In the traditional paper printing creasing process, paper positioning and calibration are usually done manually, which is not only time-consuming and labor-intensive, but also prone to errors, resulting in deviations in the creasing position. In addition, the pressure and depth during the creasing process often rely on the operator's experience and feel to adjust, which is difficult to achieve precise control, thus affecting the quality and consistency of the creasing. At the same time, the traditional creasing process is often limited to a single creasing texture and cannot meet the market's demand for diversified and personalized creasing effects.

[0004] Therefore, we made improvements on this and proposed a paper printing indentation processing technology. Summary of the invention
