Radio Frequency identification is the newest method of identification to be applied to organizations and products. RFID tags are printed with unique labels printers and encoders.
While there are numerous designs, standards and protocol that might be adopted for printing these tags, a set of hassle free suggestions can be delineated that would encompass the best practices in the field. Wise label printers and encoders use a media program with an RFID inlay, which is a mixture of a chip and an antenna. This is usually implanted inside the material of the label. The use of radio frequency transmission by the printer enables the RFID encoder inside it to write the data on the tag. The transmission focuses only on the location of the tag inside the label, even though the graphics, text and the barcodes get printed in the customary manner.
Some of the tips to make printing of tags hassle cost-free include:
Choice of Media is essential since it have to match in with the printer and application. This is imperative for RFID tags given that they characterize minimal interference, have a huge reading variety, and give data integrity. These traits are possible only with smart labels of the best high quality. The intelligent label has to be able to transfer information precisely and accurately while guarding the inlay and avoiding interference of any sort.
Chip position must match the Printer and Encoder: Companies needing smart labels need to be conscious of their inlay needs, designs and frequency of their applications. The media they select have to be aligned to the model of the encoder and printer so that the encoding approach is smooth. The media provider has to preserve in thoughts the specifications of the printer while designing wise labels and printers carry a list of the designs they support.
Sensible labels must not use foil or metal-primarily based labels given that they interfere directly with RFID. They limit its range of operation and also impede the encoding procedure.
Liquids also interfere with the functioning of the RFID technique. They tend to absorb RF signals and stop them from becoming study. The adhesives put on label media are a liquid supply, attracting water, which once again leads to issues of performance efficiency. Hence synthetic media and laminates are preferred because they do not absorb water.
Smart media labels operate within a wide temperature variety and this have to preferably be kept among –51 and +95 degrees centigrade.
Electro static discharges have to also be restricted and their risk increases at greater altitudes with low humidity levels. ESD tends to adversely have an effect on sensible label performance, and for that reason protection need to be supplied from it.
The selection of a printer must be made right after taking into consideration their deliverables and preference have to be provided to printers possessing versatile error settings so that external intervention is not constantly essential each and every time a issue arises and can be resolved by adjusting the settings.
Printer placement at a affordable distance from other RF items also helps to improve efficiency of the printer.
Success of the encoding approach would be larger if the printer could perform tag high quality checks at two levels, when just before receiving the information and subsequent soon after the information has been written on the chip to guarantee its accuracy. The goal behind this is to assure appropriate alignment of the label edges so that the tag can be completely encoded.
Printers have to be programmed to retry encoding soon after a failed attempt since frequently a second try is effective. If on the other hand, the printer concerns a warning soon after a failed attempt, this may possibly lead to wastage and reduce the yield rates.
Damaged labels have to not get printed and should as an alternative be stamped with a “void” message and segregated from the ones ready to be printed.
RFID systems need to adopt potent printers, which can be programmed to situation warnings about persisting troubles rather than have to be switched off. A shut down can trigger a different set of difficulties.
Optimum placement of the label is important, and this should be away from liquid and metal.
If all these methods are followed and checks carried out prior to the program becomes functional, printing RFID smart labels would certainly turn into hassle free for a lengthy, long time.
