Using EntomoLabels, you can make quite complex templates. For example, for the herbarium – the pattern is copyrighted, I only used it to check the program’s capabilities.
Download the template (without NHM logo) and see how it was made. (Right click on the link and save the template in the folder .. Templates)
labels.entomo.pl/Templates/HerbariumScale.elt
Download the template with DataMatrix code and automatic numbering and check how it works. (Right click on the link and save the template in the folder .. Templates)
