Abstract
A produce (e.g. fruits and vegetables) marking system is used to etch the skin of a piece of produce with an identifying mark. The first embodiment of the system uses a laser to emit a high intensity light beam to form the identifying mark. The second and third embodiments of the system use a dot matrix printer head. In the second embodiment, the pins of the printer head directly contact the produce skin to etch an area of the skin to form the identifying mark. In the third embodiment, a thermally conductive ribbon member is placed between the printer head and the produce. The pins of the printer head impact the ribbon member thereby forming a hot spot on the ribbon member, which in turn, etches the skin of the produce to form the identifying mark.
