Variable-information coding applications on product packaging are becoming more and more common. Those seemingly simple and even monotonous graphics, one-dimensional codes, two-dimensional codes, and digital codes, are occupying our world. Variable-information coding carries product traceability, Logistics management, anti-counterfeiting, interactive marketing and other extremely important missions enhance the function and value of product packaging. The small box coding technology of Kirui Technology, which has grown up with the implementation of the electronic drug supervision system, has been developed in the drug supervision coding market, but it is no longer limited to this market. It is suitable for all kinds of packaging boxes and other codes. Cardboard products are assigned codes, such as clothing tags, tickets, product ID cards, staff listings, promotional cards, etc., and are perfectly embodied in a series of products. Arnoldjet provides more coding technical solutions and high-quality and comprehensive technical support and services for the printing and packaging industry. Arnoldjet Inkjet Technology first started with coding equipment, with the concept of creating a precision printing machine, lean design, selected accessories, and meticulous workmanship, creating a highly reliable and stable equipment, which makes the positioning accuracy and repeatability of the printing code. The positioning accuracy is reliably guaranteed. The focus of variable information coding is not only the coding equipment. Because we are well versed in the drawbacks of software systems and coding equipment that are not in the same home, we have developed our own software system with great effort to achieve the best results on the production site. In the same batch and different batches, automatic identification and skipping of ineffective codes such as repeated codes, wrong codes, garbled codes, etc., and there is no need to exit the printing program during the temporary shutdown, so there is no waste of coding; at the same time, variable data printing Smaller steps precisely control the size of the ink droplets to obtain an excellent printing density with a critical ink volume, and the density adjustment is close to stepless.
