Abstract:
A method, non-transitory computer readable medium and apparatus for generating a multi-layer correlation mark via a monochrome printer are disclosed. For example, the method includes setting a first scalar value of a channel of the monochrome printer, setting a second scalar value of the channel of the monochrome printer, generating a first layer of the multi-layer correlation mark at the first scalar value of the channel, generating a second layer of the multi-layer correlation mark at the second scalar value of the channel and printing the multi-layer correlation mark comprising the first layer at the first scalar value of the channel and the second layer at the second scalar value of the channel.
