Embodiment Construction

[0030] Regarding the characteristics and practical operation of the present invention, the preferred embodiments are described in detail as follows in conjunction with the accompanying drawings.

[0031] First please refer to figure 1 , is the flow chart of making the information variable barcode disclosed in the present invention. This method first determines the information A and B to be displayed in two different temperature ranges (below normal temperature T1 and above high temperature T2, T1≤T2), and at the same time determines the α ink that can develop color below normal temperature T1, and the information that can be displayed on high temperature T2. colored beta ink. Then calculate the barcode a of information A and the barcode b of information B. The same part S1 and the different part S2 of barcode a and barcode b are calculated. At the position where the information variable barcode is to be placed, place ordinary ink at the position of the "bar" in the p...

Abstract

The invention discloses a barcode (the barcode also can be called a mixed barcode) with changeable information and a manufacturing method of the barcode with the changeable information. The barcode with the changeable information can display different information in different temperature ranges and is characterized in that two barcodes with different information contents are arranged at the same position simultaneously, and multiple barcodes can respectively display different information in different temperature ranges. By the adoption of normal printing ink and temperature-change ink in a combined mode, the barcode with the changeable information and the manufacturing method of the barcode with the changeable information enable the barcode technology to have the functions of environmental temperature sensing and information content changing according to different environmental temperatures, and can increase the information capacity of the barcode technology and improve the anti-fake capacity of the barcode technology.

Description

technical field [0001] The invention belongs to the technical field of barcode coding and production, and relates to a method for making barcodes with variable information, in particular a technique for placing barcodes with different information at the same position by using common ink and multiple temperature-variable inks in combination. Background technique [0002] Bar code technology has been applied in various fields of social life. The more popular barcodes now include: one-dimensional barcodes and two-dimensional barcodes. A barcode is a mark composed of a set of regularly arranged "bar-empty sequences" and corresponding characters. "Bar" refers to the part with low reflectance to light, and "empty" refers to the part with high reflectance to light. The data composed of these bars and spaces expresses certain information, and can be read by specific equipment and converted into binary and decimal information compatible with computers. The current barcode technolo...
