Description

Technical Field

[0001] The invention relates to infrared detection technology, in particular to an infrared invisible function detection device for ink. Background Art

[0002] Invisible ink, also known as colorless fluorescent ink, is an ink that is colorless or nearly colorless under normal lighting conditions, but fluoresces or changes color under specific ultraviolet or infrared light. The following are some common applications of invisible ink:

[0003] Anti-counterfeiting printing: Invisible ink is often used in anti-counterfeiting printing, such as banknotes, passports, ID cards, tickets, certificates, etc. By adding invisible ink to printed materials, anti-counterfeiting measures can be added to improve the security of certificates and tickets.

[0004] Product packaging: On the packaging of some high-end products, such as alcohol, medicine, cosmetics, etc., anti-counterfeiting logos or specific patterns are printed using invisible inks to help consumers distinguish the authenticity and prevent the emergence of counterfeit and shoddy products.

[0005] Labels and stickers: Invisible ink can be used to make various labels and stickers, such as product labels, logistics labels, warranty labels, etc. These labels will show hidden information such as production date, batch number, serial number, etc. under specific light.

[0006] Security marking: In some occasions where security marking is required, such as documents, archives, important items, etc., invisible ink can be used for marking. These marks can only be seen under certain conditions, playing a role in confidentiality and security.

[0007] Art and Design: Invisible ink is also used by some artists and designers to create works with special effects, such as invisible patterns, fluorescent paintings, etc., to increase the creativity and interest of the works.

[0008] Print quality inspection: In the printing process, invisible ink can be used to inspect the quality of printed products. By adding invisible marks or patterns to the printed products, specific equipment or methods can be used in the subsequent inspection process to check whether the printing quality meets the standards.

[0009] When using the existing infrared invisible function detection equipment for ink, the staff is required to manually align the carrier carrying the invisible ink and then perform infrared spectral scanning. When the carrier position is uncertain, the spectral signals collected at different positions are different, which will reduce the repeatability and consistency of batch scanning. The uncertainty of the carrier position will cause changes in the spectral data, thereby increasing the difficulty of data interpretation and analysis, especially when performing large-scale scanning and comparative analysis. In addition, the uncertainty of the carrier position will lead to uncertainty in the position of the data finally presented by the scan, affecting data comparison and observation.
