Samples printed with Series R4900 and R6000 ribbons using a BradyPrinter™ THT Model 300X Thermal Transfer Printer. Labels printed using a 3:1 ratio barcode with a 5 mil narrow X dimension bar. Test was conducted at room temperature after 24 hour dwell. Testing consisted of 5 cycles of 10 minute immersions in the specified chemical reagent followed by 30 minute recovery period. Samples rubbed 10 times with cotton swab immersed in test fluid after final immersion.
