A monochromatic binary printer model at the cluster level defined by the halftone frequencies is presented in this paper.
The halftone process using a cluster halftone screen creates halftone structures with aligned clusters within halftone cells
tiled to fill the image plane. Each halftone cell, or each tile, can be treated as a "primary color", which can be calibrated,
or macroscopically measured, from a corresponding halftone pattern. The cluster-based printer model estimates the
average color of a halftone pattern containing different halftone cells using a modified Neugebauer spectral
(colorimetric) color mixing model incorporating the Yule-Nielsen effect. A method based on the proposed clusterbased
printer model for quickly and accurately characterizing the complete tone reproduction curve (TRC) for multicenter
halftone screens is also described with the experiment result.
