There have been random cases of the incorrect ribbon being sent to users by Alpha Systems and I suspect this is what happened in your case.  This does indeed lead to print sloughing off the media in alcohol.  However, we have not had any issue with our labels using SDR ribbon in 17 years in multiple collections here at KU.  The labels have stood up to all conditions without any issue – no fading, no cracking, no yellowing, no print sloughing in multiple solutions – 70% and 95% ethanol, conc. and 4% formalin and glycerin – fatty, oily specimens of fish, herps as well as invertebrates.  Unlike any other printing medium, the spun bound polyester has also been subjected to commercial, professional aging tests that justify its use in alcoholic solutions.  I have however had numerous issues with dot matrix, ink jet and laser printed labels of various kinds over the 17 years that I have been involved with fish collections.

To me, this seems like a lot of additional effort (not to mention the
fact that this technology is on its way out and ever harder to
maintain) to produce labels that are inferior in both quality and
longevity to those produced by thermal transfer printing on spin bound
polyester media.  The initial monetary investment may be greater but
the reward in terms of Museum quality labels that will stand the test
of time far exceeds this.

We've had thermal printer labels self-destruct when placed in ethanol
solution, with the layer bearing the printing softening such that any
friction causes it to rub off. I wouldn't consider thermal printing to
have passed the test of time just yet. ;-)
