Anti-channel conflict code-spurting printing ink and its preparation method

Abstract

The invention relates to an anti-channel conflict code-spurting printing ink and its preparation method. The invention firstly provides a code-spurting printing ink. Weighed according to the gross weight of the code-spurting printing ink, it is composed of the following raw materials of: by weight, 0.1-0.8% of a colorless organic fluorescent coloring agent, 2-10% of an organic solvent soluble dye, 1-10% of polymer resin and 80-90% of an organic solvent. The invention also provides a preparation method of the above code-spurting printing ink. The code-spurting printing ink provided by the invention remains properties and functions of a common printing ink, and is also endowed with a certain anti-channel conflict, anti-tamper and anti-counterfeit hiding performance, thus effectively hitting counterfeiters, increasing difficulty in counterfeiting to a large extent and avoiding further forgery. Simultaneously, according to the code-spurting printing ink, plain code and secret code jet printing can be realized only with an inkjet printing machine. Therefore, it is not necessary for manufacturers to increase new inkjet printing machines for secret code jet printing, thus greatly simplifying production process and saving production cost.

Description

technical field [0001] The invention relates to a code-jet printing ink and a preparation method thereof, in particular to a code-jet printing ink for preventing cross-selling and a preparation method thereof, and belongs to the field of printing ink for a code-jet machine. Background technique [0002] On the surface of the packaging of food and medicine, there are numbers, English letters or Chinese characters printed by inkjet printers. These information generally exist in the form of barcodes. They clearly indicate the production date and also imply the production batch of the product. Detailed information such as times, production equipment, place of delivery and sales place. The existing coding process is to spray clear codes, that is, information recognizable under visible light, which is convenient for consumers to identify. [0003] Due to the vast territory of our country and the difference in living standards, for some commodities, there are large differences in ...

AI Technical Summary

Problems solved by technology

[0007] 1. Since the inks used by the two cannot be printed by the same inkjet printer, it is necessary to use different inkjet printers to print the dark code and the clear code, which will increase the production cost

[0008] 2. Due to the aesthetic requirements of the product packaging, the available printing positions are limited, and sometimes it cannot meet the requirements of printing clear and dark codes at different positions: the clear code is represented by a black barcode or digital code, usually in white or close to white product packaging Spray printing on the background color, good recognition and detection effect; the secret code emits light and color under the irradiation of fluorescent lamp, and the recognition and detection effect is good on the surface with a single background color

[0009] 3. Code detection will increase production costs: Code detection requires fluorescent lamp equipment to be added to the production line to detect the printing effect of codes, and additional stations, equipment and testing personnel are required on the production line, which greatly increases production costs

[0010] 4. The collection of secret code information needs to be installed on the production line with additional camera equipment equipped with fluorescent irradiation, as well as software related to plain code and secret code information, which increases production costs
