Recovering Neugebauer colorant reflectances and Ink-spreading curves from printed color images

Roger Hersch, Thomas Bugnon

Spectral reflection prediction models, although effective, are impractical for certain industrial applications such as self-calibrating devices and online monitoring because their calibration requires specific color-constant calibration patches. Using the ...

Synthesis of authenticable halftone images with non-luminescent halftones illuminated by an adjustable luminescent emissive layer

Roger Hersch, Julien Alexandre Andres

A method and computing system are proposed for producing an authenticable security device with two sides. The verso side is covered with an adjustable luminescent emissive layer formed by invisible luminescent ink halftones and possibly a UV absorbing prin ...

Spectral Prediction of Juxtaposed Halftones Relying on the Two-by-two Dot Centering Model

Roger Hersch, Vahid Babaei

In a color reproduction workflow, spectral prediction models are useful for establishing the correspondence between colorant sur- face coverages and resulting printed halftone color. Spectral predic- tion models enable calculation of the color gamut and es ...
