Abstract
A printing system is disclosed. The printing system includes a printer controller to receive optical density (OD) measurement data corresponding to application of a halftone pattern using ink on a medium in a printing system and calculate a predicted OD versus normalized ink coverage relationship for the printing system based on the received OD measurement data.
Claims19
A non-transitory machine-readable medium including data that, when accessed by a machine, cause the machine to:
- receive optical density (OD) measurement data corresponding to application of a halftone pattern using ink on a medium in a printing system;
- and
- calculate a predicted OD versus normalized ink coverage relationship for the printing system based on the received OD measurement data, wherein the predicted OD versus ink coverage relationship is calculated using Weibull distribution function parameters.
A printing system comprising:
- a printer controller to receive optical density (OD) measurement data corresponding to application of a halftone pattern using ink on a medium in a printing system and calculate a predicted OD versus normalized ink coverage relationship for the printing system based on the received OD measurement data, wherein the predicted OD versus ink coverage relationship is calculated using Weibull distribution function parameters.
A method comprising:
