Zebra 3007810 Thermal Label - Permanent Adhesive - 51 mm Width x 25 mm Length - 2700 / Roll - Rectangle - Thermal Transfer - Polypropylene - 8
Thermal transfer involves the thermal print head elements (dots) heating the backside of a thermal transfer ribbon to melt and transfer the compounds on the front side of the ribbon to the label. Print head life in direct thermal printing applications is significantly reduced when compared to thermal transfer printing applications. Generally speaking, a company should anticipate direct thermal print heads providing an expected lifetime of 25% - 50% of a thermal transfer print head. As an example, if a company is printing 10 million, six inch long labels per period with an expected thermal transfer print head life of 4 million inches, they would expect to replace the print head 15 times. If the same application were direct thermal, they would expect to replace the print head 30 – 60 times. Depending upon throughput volumes, the cost differential may be significant and has to be considered in any evaluation.
