Brief description of the bottles by marking unalterable and can be read automatically at the volee.

摘要

The method involves obtaining reading of marking by interpreting color alteration forming positive or negative image between a support e.g. bottle body (1), and a coating (2) resulting from a hardened marking (3), where the marking is read at rapid speed with strong discrimination of colors. The hardened marking obtained by cutting or deformation is unalterable nature, and combined with the coating so that the marking is read and interpreted when the marking stopped in appropriate speed, in case of deterioration of the coating and the marking is no longer read at high speed. An independent claim is also included for a hardened and optimized contrast marking comprising a coating providing a contrast with respect to a support.
