Description

Technical Field

[0001] This utility model relates to the field of offset printing, specifically to a real-time detection and feedback device for the suitability of offset printing inks. Background Technology

[0002] Offset printing for cigarette boxes is a printing process that specifically refers to the method of transferring the image and text on a printing plate to the cigarette box packaging using a rubber blanket. During the printing process, the image areas of the printing plate are oleophilic, absorbing ink; while the non-image areas are hydrophilic, repelling ink and absorbing moisture. Therefore, when the printing plate comes into contact with the blanket, the ink from the image areas is transferred to the blanket, and then from the blanket to the cigarette box packaging, thus completing the printing of the image and text.

[0003] In offset printing of cigarette boxes, a real-time offset ink suitability detection and feedback device is used. This device integrates multi-parameter sensors and an intelligent control system to dynamically monitor and automatically adjust key indicators such as ink viscosity, color, and drying speed, thereby optimizing printing quality and reducing production waste. In existing technologies, the sensor components of real-time offset ink suitability detection and feedback devices are fixedly connected with bolts. When a sensor component is damaged and needs to be disassembled and replaced, it is cumbersome and inconvenient. Therefore, those skilled in the art have provided a real-time offset ink suitability detection and feedback device to solve the problems mentioned in the background art. Utility Model Content
