RFID antenna printing is a very precise printing process. Due to the trajectory printed and the spacing between tracks, the precise shape size directly determines whether the antenna can work properly as required. Rotary screen printing is a very effective printing method for RFID antennas, and is the only printing method that can print thick ink onto the surface of a material, and the thickness of the ink can be from several micrometers to 300 micrometers. In fact, this kind of printing method can also realize the continuous printing of printing patterns, which can be connected once to get the precise appearance pattern, and is quick and accurate.
With more than 40 years of experience in rotary screen printing and continuous technological updates, STORK PRINTS can provide comprehensive technical solutions for RFID antenna printing. Rotary screen printing has become the key to all major RFID antenna processing methods, including corrosion, plating, and direct printing. In the following ways, the screen printing method of rotation plays a crucial role:
A Corrosion method Printing anti-corrosion coating to copper base layer
B Plating method Print plating catalyst ink before plating
C Direct printing method Directly printed conductive ink forming antenna

Accuracy STORK's RSI unit has a printing accuracy of +/- 0.1 mm, making it possible to achieve the accuracy of the coil. Even in very fine HF coils, the spacing and thickness between 15 μm and 25 μm can perform perfectly. STORK can provide printing widths of 10 inches, 16 inches, 20 inches and 24 inches respectively.
Speed STORK's rotary screen system proved to be able to achieve stable printing of fine antennas at speeds exceeding 30 meters/minute, and the output can be as high as 50,000 antennas/hour.
The achievement of stable accuracy and speed is achieved by electroplating a pure metal nickel screen plate. The plate structure of the hexagonal honeycomb structure can make the ink transfer smoothly, and its stable structure can also increase the stability of the operation of the printing press. This means that printers can achieve high-efficiency and low-cost operation while ensuring high-quality antenna printing.
Lifespan STORK's rotary screen printing achieves the best control over material costs. Its rotary screen printing plates can achieve a printing life of 500,000 meters and can be reused up to 15 times.
Special drying and curing systems are necessary for the drying and curing of RFID antennas. With professional experience, STORK designed and manufactured a drying and curing system specifically for RFID antenna printing, which ensures stable RFID antenna printing.
