Optical density monitoring mechanism

At least one computer readable medium having instructions stored thereon, which when executed by one or more processors, cause the processors to:

• receive first ink deposition data representing an output ink amount versus a first input digital count for each of a plurality of color planes in a first halftone design;
• receive second ink deposition data representing a second output ink amount versus a second input digital count for each of the plurality of color planes in a second halftone design;
• generate first optical density (OD) response data for each of the plurality of color planes based on the first ink deposition data, wherein the first OD response data represents a first OD value versus the first input digital count for the first halftone design;
• generate second OD response data for each of the plurality of color planes based on the second ink deposition data, wherein the second OD response data represents a second OD value versus the second input digital count for the second halftone design;
• determine whether a difference between the first OD response data and the second OD response data exceeds a predetermined threshold;
• and
• transmit a signal upon a determination that the difference between the first OD response data and the second OD response data exceeds the predetermined threshold.

A method comprising:

• receiving first ink deposition data representing an output ink amount versus a first input digital count for each of a plurality of color planes in a first halftone design;
• receiving second ink deposition data representing a second output ink amount versus a second input digital count for each of the plurality of color planes in a second halftone design;
• generating first optical density (OD) response data for each of the plurality of color planes based on the first ink deposition data, wherein the first OD response data represents a first OD value versus the first input digital count for the first halftone design;
• generating second OD response data for each of the plurality of color planes based on the second ink deposition data, wherein the second OD response data represents a second OD value versus the second input digital count for the second halftone design;
• determining whether a difference between the first OD response data and the second OD response data exceeds a predetermined threshold;
• and
• transmitting a signal upon a determination that the difference between the first OD response data and the second OD response data exceeds the predetermined threshold.
