This standard only specifies the quality requirements for the anti-counterfeiting characteristics of thermal color-changing anti-counterfeiting inks. Therefore, it needs to be used together with the relevant requirements (such as the reduction and display of various printing methods such as lithography, gravure printing, silk screen printing, etc.) during testing. This standard was proposed by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China. This standard is under the jurisdiction of the National Anti-counterfeiting Technical Committee. The basic units of this standard are: the Anti-counterfeiting Product Quality Supervision and Inspection Center of the Ministry of Public Security, Beijing Zhongbiao Guoan Technology Co., Ltd., and the drafters of this standard are: Yu Xiaoping, Liu Shubin, Wang Shuzi, Yue Yuhua, Gao Lisheng GB/T18752—2002
Thermosensitive anti-counterfeiting ink is a new product in a series of anti-counterfeiting inks. This standard is formulated to standardize the product quality of thermal anti-counterfeiting inks and put forward the requirements for anti-counterfeiting characteristics, so as to facilitate future quality supervision. The applicable temperature range specified in this standard exceeds the appropriate temperature range of 330°C specified in TGB/T17004-1997.
This standard describes the anti-counterfeiting properties of thermal sensitive anti-counterfeiting oil display and the characteristics of oil penetration as two parts, with the focus on the anti-counterfeiting properties of thermal sensitive anti-counterfeiting oil display. The requirements for the characteristics of the oil itself are not further specified because the characteristics of the oil itself can refer to the corresponding current national standards and inspection bases for the printed version.
