SEE BELOW

 

Sleeves were printed with R6000 Series, R4300 Series, R6400 Series and Brady 356126 thermal transfer ribbons, allowed to dwell 24 hours prior to shrinking on appropriate sized wires and testing.  Testing was conducted at room temperature and consisted of 5 cycles of 10 minute immersions in the specified chemicals followed by 30 minute recovery periods.  After the final immersion,  the samples were removed from the test fluid and the printed image rubbed 10 times with a cotton swab saturated with the test fluid. The rating scale below shows the effect to the quality of print for each sample.

 

Unless otherwise noted, there was no visible effect to the printed image prior to rubbing for the above ribbons.
