Cartridge Clustering for Improving Tone Prediction Accuracy in Calibration for Color Electrophotography
Abstract:The variation of supplementary components, such as cartridges, has been observed to have an impact on the color electrophotographic (EP) process. The preliminary study shows that the cartridge variation affects the calibration sensor mapping which predicts colorimetric tone reproduction (CTR) values on printing media as a function of internal sensor readings from halftone patterns printed on the printer transfer belt. This paper presents the result of the data-driven study to identify the cartridge patterns and further improve the tone prediction accuracy in calibration of EP platform. First, the constrained hierarchical clustering method was applied to generate a variety of cartridge groups according to the characteristics on the sensor mapping. A new sensor mapping model including a cartridge clustering module was proposed not only to compensate for environmental and consumable conditions, but also to consider cartridge variation. The experimental results show that overall accuracy of the sensor mapping can be improved by ∼ 40% on average after considering the cartridge factor.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
