To save time for mass printing and encoding applications, RFID Printers are created to serve both as an encoder and the verifier for all tags that passes through. The unit reads and then encodes the tags with the new information and re-reads the tags before they are released. This is so that it verifies the tags accurately and has the correct new information.
On average an RFID printer depending in the printer’s speed and label size, an RFID printer prints approximately 20 labels per minute. Due to its high accuracy, RFID printers are quick and efficient and therefore prints for applications such as supply chain, manufacturing, transportation, logistics, retail and healthcare.
There are two types of printing; Direct Thermal and Thermal Transfer. The Direct Thermal uses less frequency in RFID application this is due to the paper naturally degrading over time because it is open to heat and sunlight.
What are the perks for using Direct Thermal?
Well, since there is no need to purchase for printer ribbon, Direct Thermal printing is cheap. However as for Thermal Transfer, it heats the ribbon and therefore it melts and transfers it in the form of the preferred pattern.
The most common printing method used in RFID labels are the Thermal Transfer and this is due to its lifespan on printed media. Also, another perk that adds to this is the possibility of gaining the materials and additionally coping with the environment such as the temperature and light. However, the cons for Thermal Transfer is the cost of regaining the printer ribbon.
As for Thermal Transfer printing, ribbons are crucial and it can be bought for a reasonable price. There are several types of ribbons available such as Wax Ribbon, Wax/Resin Ribbon and Resin Ribbon.
Wax Ribbon is used in applications without abrasion or chemical exposure. However, Wax/Resin Ribbon is used in applications that may encounter moderate abrasion and exposure to chemicals. It can also be used where the UL certification is required. Resin Ribbon uses synthetic and polymer materials. It can also be used in UL certification.
