In the 244th issue of the Graphic Arts Society Monthly, I published the article "3W of RFID and New Opportunities in the Printing Industry", which attracted the attention of the industry. Nearly on September 9-15 this autumn, the Chicago Printing and Paper Processing Exhibition will showcase and give lectures on RFID samples and technologies for further introduction.
In general, RFID The emergence of RF tags in the industry has caused a lot of heat waves, and is considered a possible alternative to bar code, providing the printing industry with a potential new product and market. In fact, RFID is not only a new label that can replace barcodes, it will bring amazing improvement in the management efficiency of shopping malls, supermarkets, warehousing and logistics. Don't say anything else, the regular shelf or warehouse inventory of labor and money can be saved, which can save the owner how much labor expenditure, while the consumer to the supermarket to buy goods, push the full car of the purchase to checkout When you have a mouth, you don't have to queue up to pay for it. How convenient it is! It is no wonder that not only the printing industry, but the whole society is concerned about the adoption of RFID technology. But this "probability" has not yet become a universal "reality." Because RFID has some problems in technology and application that need to be explored and improved.
I learned from sporadic reports that the conductive inks used in RFID have been developed by Flint Ink and have been designated by its Precisia subsidiary for its application development, in conjunction with the packaging and printing industry. Karthy Marx, head of marketing at Flint Ink, believes that “development from technology to market applications is a reasonable and necessary process” and says: “We don’t know what else we should know.” That’s her One of the main reasons for participating in the organization of RFID lectures at the Chicago Show this fall.
Kleper, a professor at the Roche Institute of Technology (RIT) in the United States, believes that RFID is a good development opportunity for printers. However, the printing of RFID antennas is only in the initial stage of the knife, and the printing process requires skill and high set. Quasi-precision is more stringent than general merchandise printing requirements. In this regard, S.Zaccone, president of Graphic Solutions International, said more specifically: “When printing with conductive inks, overprinting accuracy and ink coverage are key to success. For flexo: register within 5 mils Even if it is good, but the RFID chip surface is generally only 20mils, but there are 4 to 10 bonding points, each point takes up about 2mils position, that is: the overprint accuracy can not exceed 1mil, which is the limit of offset printing ink resolution There are many limits on the resolution of translucent conductive inks. Moreover, RFID chips must have a full registration requirement of 2-3 layers, which is not simple. And sometimes the wafers are good, but they are printed. There may be pinholes in the antenna that may fail during use.
For printers, RFID is certainly a new business opportunity, but it is also a question that printers should consider making decisions when they only invest in RFID chip antenna printing or in conjunction with processing equipment such as wafer mounting. It must be investigated and discussed in conjunction with the market and the consignor.
Conductive inks contain more silver, which is not only a cost issue, but a larger problem is recycling in the future to avoid environmental pollution as much as possible. With the promotion of the application, the more recycling measures need to be considered.
Therefore, RFID, it is not easy to say that it is not easy to love you!
