The use of advanced printing technology gives new life to RFID technology to force the printing industry and the electronics industry more closely together. This makes the RFID tags to printers, printing materials and equipment suppliers to raise the new demand. In the mean time, it also opens a new product line, a new profit growth and new markets. Because the passive RFID tag printing of "conductive ink" when its printed materials need to use the high price of silver. This leads the RDIF tag cannot reduce the cost. This study used true-experimental research method by using the screen printing. The different size of the halftone dots is used to adjust the amount of conductive ink to save the amount of conductive ink reach RFID tags cost down. But still maintain the communication effectiveness of RFID, and then further accelerate the market development of RFID tags. The experiment used the different printing resolutions, different papers and different halftone dot sizes (dots and dots must be connected without breaking). After screen printing is completed, put the strap IC chip onto the RFID tags and measure the effective distance of the RFID tag. The results of the research: is smaller print resolution, the higher the amount of conductive ink; the larger the print halftone dot size (the closer to the line art) the better reading distance. However, the amount of ink and use the reading distance must find its place point. The saving of the ink becomes meaningful and significant. Therefore, we do believe that by changing the halftone dot size is a feasible solution and the cost of the RFID tag can be reduced. Furthermore, by using the same RFID antenna design, the use of different dot sizes should be have different distances of the RFID tag for the different end applications.
