AI Technical Summary
Technical Problem
Existing laser anti-counterfeiting technologies are complex to manufacture, costly, and easily counterfeited, making it difficult to effectively protect the security of goods.
Method used
Hydrogel random laser labels are prepared using inkjet printing technology. Random lasers are generated by the disordered dispersion state of the hydrogel medium. The authenticity of the labels is determined by combining neural network model recognition or vibration frequency recognition method.
Benefits of technology
It achieves the uniqueness and anti-counterfeiting of labels, avoids counterfeiting, quickly and accurately identifies the authenticity of labels, reduces production costs, and is suitable for mass production.

Abstract
本申请公开了一种随机激光标签的制作及防伪方法，用于制作随机激光标签，并利用该标签实现防伪的应用。本申请方法包括：将一定质量的丙烯酸、丙烯酰胺、聚丙烯酸钠、纤维素、金纳米棒以及聚乙二醇双丙烯酸酯、2‑羟基‑2‑甲基苯丙酮和荧光染料混合均匀，得到水凝胶前驱体溶液；然后将所述水凝胶前驱体溶液注射到喷墨打印系统的储液瓶中，通过喷墨打印的方式制作标签图案；打印完成后再利用紫外固化的方式使所述水凝胶前驱体溶液交联，完成水凝胶标签的制作；最后利用泵浦光照射水凝胶标签，通过光谱仪读取标签辐射的随机激光光谱中所含波峰的波长信息，利用不同水凝胶标签所携带波峰的波长信息不同且无法仿制的特性，实现标签的防伪应用。
