We have been using Pelikan No. 50 Special Black India Ink for our wet
specimen labels for eons (since before I started here in 1967). This ink is
no longer available and the replacement, Koh-I-Noor No. 50 Special Black may
be water proof but is not alcohol proof.
I checked the inks tested by Steve Williams (Williams & Hawks, 1986.
Inks for documentation in Vertebrate Research Collections. Curator
29/2:93-108) and found many had different (new) product numbers and most
were not satisfactory. We are currently using Hunt Speedball Super Black
India Ink (product number 3268, now 3338). It seems to be very slow drying
(2 minutes plus) and still bleeds.
I have tried several Koh-I-Noor waterproof inks, no joy. Ditto Higgins
and Rotring. Some look good but wipe right off the label after a short
immersion (lack of abrasion resistance).
Our overworked conservationist has suggested that the problem is my
label paper (100% rag Linen Record). I am waiting to try a sample of
Resistall high rag paper. I have noticed that many colleagues are using
acetate drafting film for alcoholic labels. These seem to be okay for
casual labels, but I like to run my labels through a laser printer, then add
archival information in a permanent ink.
If anyone out there has suggestions, please reply.
