I created a printing process which can print shipping labels using the beet based ink.
Beets contain a protein called Betacyanin which can be made to denature and change color when heated. These printed packaging labels are created by coating paper in a formulation of the beet ink I developed. I printed the text using the kind of thermal printer used in most retail receipt printing. Currently, thermal printer paper contains BPA; a chemical linked to a staggering number of health problems including cancer, and has already been removed from products like baby bottles. Beet based thermal ink represents an all natural alternative for receipt printing.
