Hi All,<br>
<br>
I was intrigued by Mark O'Brien's comment (Hi Mark)! I have learned
(and taught) just the opposite: do NOT use inkjet & bubblejet
printers because the letters readily dissolve in EtOH (and I've
witnessed that). In the case of simply xeroxed labels, the letters
readily life off the paper. As for laser printers, it has been my
experience (and, alas, I'm old enough to have had a lot of
experience) that as long as the heat is sufficient, the plasticized
carbon will generally NOT lift off the paper. I am looking at EtOH
laser-printed labels that were printed more than 25 years ago and
have been in 80% EtOH since - they look "good as new." <br>
<br>
I also concur with Paul's observation:<br>
<br>
<font color="#330099">We have noticed in the last few years that
modern laser printers seem to be using less heat, and thus are not
bonding inks as tightly, especially into thicker paper stock.</font><br>
<br>
For this reason, we now - as a matter of protocol, immediately take
printed labels from the laser printer to a drying oven where we heat
them for at least several hours (which not infrequently becomes over
night as forgetful minds work). In any case this has served us
well. We now generally use Bright White, acid free, 65 lb. archival
quality paper. This weight just falls into the "cardstock" category,
but I find somewhat "lighter" 100% cotton paper - <i>circa</i> 32
lb. worked well, too.<br>
<br>
Great - and very important - topic!<br>
<br>
Cheers, <br>
<br>
