Analysis of the packaging box coding scheme.

When formulating a packaging box coding scheme, it is necessary to understand several issues such as the coding requirements of the packaging box, the coding method, and the materials of the packaging box. Then, based on these coding requirements, a perfect packaging box coding scheme can be developed. Coding requirements: mainly refers to the content of coding, the main content is divided into fixed data and variable data. Fixed data mainly refers to text, bar code and graphics that will not change in all stages of the product. Variable data refers to product batch, time and production date, product shelf life and other information. With the widespread use of two-dimensional codes, variable two-dimensional code information is also regarded as variable data. Printed variable one. Coding method: At present, there are many ways to achieve coding on the packaging box. According to the working principle of the inkjet printer, it can be divided into contact coding and non-contact coding. The typical representative of contact coding is to use labels to identify products. The label can be printed outside the production line, and then the printed label can be manually pasted onto the packaging box by hand. The advantage of label coding and marking is that it can provide high-quality coding effects, and the two-dimensional code and barcode marking have obvious advantages. The disadvantage is that the label printing process is cumbersome, requires more manual operations, and the production efficiency is low. The typical representative of non-contact inkjet is to use inkjet printers to directly print on the packaging box. Suitable models are high-resolution inkjet printers, large-character inkjet printers, and thermal foam inkjet printers. Both high-resolution inkjet printers and large-character inkjet printers use non-contact inkjet coding methods to achieve identification, and use appropriate models according to the coding requirements. High-resolution inkjet printers are generally suitable for adsorptive and semi-absorptive materials, and the achieved inkjet effect is close to that of printed matter, with a resolution of 300dpi. Therefore, the advantage of the two-dimensional code inkjet is more obvious. The working principle of the large-character inkjet printer is the pressure valve type, and the coding effect is mainly dot matrix font. The advantage is that the coding speed is fast and the coding efficiency is high. Thermal foaming inkjet printer (TIJ) is also known as high resolution inkjet printer. The accuracy of the inkjet code is high. The resolution of the two-dimensional code and barcode identification can reach 600dpi, the inkjet effect is clear, and the two-dimensional code can be identified. With a rate of over 99%, it is a real two-dimensional code inkjet printer. In terms of the materials of the packaging boxes, there are many material classifications, such as corrugated packaging boxes, laminated packaging boxes, etc., according to different materials, the models to choose from are not the same.
