[Abstract]:Radio Frequency Identification (Radio Frequency Identification.RFID) technology has been widely used in commodity packaging, transportation, logistics traceability and so on. At present, the common printing methods of RFID label are etching, flexography, screen, etc. Among them, etching printing is not environmentally friendly, environmental pollution is serious, and the production cycle of flexo and screen printing is long. Ink jet printing is controlled by computer to transfer the functional ink directly to the substrate, which has the advantages of high accuracy, high speed, good conductivity and wide range of materials. Therefore, it is the research trend to use RFID tag antenna in inkjet printing form and jet printing on substrate. In this paper, the RFID tag antenna is printed by ink-jet printing with non-granular conductive ink, and the process of printing RFID tag antenna by inkjet printing is explored. The main research content is to measure and optimize the existing non-granular ink, select the ink with excellent conductivity and high stability, and use IJDAS300A inkjet printer to spray the RFID label antenna on the modified poly (ethylene terephthalate) base material. Based on the systematic analysis of the factors that affect the label quality, the process parameters of jet printing RFID label are determined by orthogonal experiment, and the label antenna of jet printing is encapsulated. It is used on the clothes tag to realize the function of following the goods in the logistics. The conclusions are as follows: the stability of the ink can be improved effectively by adding the surface active protectant PVP to the non-granular conductive ink. At 20 鈩，
