Dear Claude, (and others)
Here in the Division of Zoology at the University of Nebraska State
Museum we are just beginning the use of computer generated (HP LaserJet
5L and 6L) labels on Byron Weston Resistall Index card stock in our fish
collection and other alcohol-stored (60-70% EtOH) vertebrates. The
LaserJet printers heat the paper and toner to about 392oF for 0.1
seconds on typical paper. We're running this heavy card stock through
and it too does not bond well in that limited heating environment. So,
what I've done is take an old Commercial 210M Dry Mount Press (very
similar to the one in University Products Archive Quality Materials
catalog) and crank up the heat (gauge is messed up but I'm probably
around 250-300oF) and heat press the tags in between paper towels for
one to two minutes. We are really having great luck with the print
staying on the tag with a scratch test but only time will tell in the
fluid. For insurance we are still hand-writing the catalog number in
india-type ink on the label too.
Side note. This old Byron-Weston Resistall we are using is acidic.
But by soaking the labels overnight in tap water we get a pH test to
Write me, please, with comments or questions.
