Subject: Barcodes


From: Erich Kesse <bm.flp>
Date: Thursday, June 14, 1990
Information re: photocopying and computer generation of barcodes. Little
consolation here.  We haven't reliable information re: manufacture, nor
have we been able to get a systems type to knock out laser print
barcodes on "acid free" paper (though I agree this should be easy
enough, even using BASIC programming and ASCII character codes), ...
however, We have successfully photocopied barcodes onto "acid free"
paper and scanned them.

Back to laser printing: Our Herbarium has been printing labels using
laser printer and buffered papers.  Various papers, the Herbarium
reports, take the ink better than others.  All things being equal:
texture of paper, consecutive printing on various papers with the same
ink jet, etc., except for buffer, it appears as though pH of paper
affects printing.  We have yet to test pH of inks.
