The Brother STe-141 tape black on transparent has been developed as a masking tape. In combination with an electrochemical process, this is used to etch marks on the underlying material. Liquids such as inks or specialty etching chemicals will print through the tape, thanks to the thermal printing technique of the P-touch labelling machines. This tape is used for direct and permanent marking and provides long lasting and legible results. The Brother STe-141 tape is 18mm wide and 3 metres long.
