Abstract
A method of imaging an imprinted substrate on a printing press is provided. The method comprises sensing light reflected by the substrate using a contact image sensor to produce data representative of the imprinted substrate. The substrate has been imprinted with different colors at a plurality of printing units of the printing press. Each printing unit comprises a plate cylinder. The method further comprises storing the data representative of the imprinted substrate in a memory.

A method of imaging an imprinted substrate on a printing press, comprising:
- sensing light reflected by the substrate using a contact image sensor to produce data representative of the imprinted substrate, wherein the substrate has been imprinted with different colors at a plurality of printing units of the printing press, each printing unit comprising a plate cylinder;
- storing the data representative of the imprinted substrate in a memory.
A method for imaging an imprinted substrate on a printing press, comprising:
- illuminating a portion of the substrate which has been imprinted with an image at a printing unit of the printing press, the printing unit comprising a plate cylinder;
- sensing light reflected by the imprinted substrate with a plurality of elements, wherein each element senses light reflected by a corresponding region on the substrate to produce data representative of the corresponding region printed on the substrate, wherein a dimension of each element is substantially equal to a dimension of the corresponding region printed on the substrate;
- and
- storing data representative of the image imprinted on the substrate a memory.
A system for imaging an imprinted substrate on a printing press, the system comprising:
- a light source configured to illuminate a portion of the substrate which has been imprinted with different colors at a plurality of printing units of the printing press, each printing unit comprising a plate cylinder;
- a contact image sensor configured to sense light reflected by the substrate to produce data representative of the imprinted substrate;
- and
- a memory configured to store the data representative of the imprinted substrate.
The system of claim 21, wherein the processor is configured to generate ink key control signals based on the ink color error.
The system of claim 20, wherein the processor is configured to detect color registration based on the comparison.
A system comprising:
- a plurality of elements, wherein each element senses light reflected by a corresponding region on an imprinted substrate on a printing press to produce data representative of the corresponding region printed on the substrate, wherein a dimension of each element is substantially equal to a dimension of the corresponding region printed on the substrate, wherein the substrate has been imprinted with an image at a printing unit of the printing press, the printing unit comprising a plate cylinder;
- and
- a memory configured to store the data representative of the imprinted substrate.
