Sasan Gooran Digital Halftoning •  High quality Iterative FM Halftoning •  Dependent Halftoning

•  Using dot-off-dot as much as possible, which reduces the color noise

•  Reducing Ink consumption

•  Hybrid Halftoning •  Combining AM and FM (FM highlights and shadows)

•  Useful for Flexography

•  Second generation FM halftoning •  Building threshold matrices by an iterative technique

•  High speed, high quality

Daniel Nyström •  Colorimetric and multispectral image acquisition

•  Calibration and characterization of an image acquisition system

•  Aim: combining spatial resolution with accurate color measurements

•  Microscopic color measurements

•  Measure and characterize color prints on microscopic level

•  Separating physical and optical dot gain

•  Halftone color reproduction models

Mahziar Namedanian

PaperOpt – Modeling of the Paper Optical System from Components to finished prints

•  Mid Sweden University

•  Innventia

•  Karlstad University

•  Linköping University

•  Halftone modeling and model verification

•  Separating physical and optical dot gain

•  Ink behavior and dot gain for different paper grades

•  Optical dot gain for different halftone dot shapes

Yuan Yuan Qu •  Color prediction models

•  Color Prediction Model based on CIEXYZ using an effective coverage map (using 3 characterized dot gain curves based on CIEXYZ values)

•  Spectral color prediction model

•  Colorant separation for multicolorant printers (CMYKcy)

•  Estimation of the surface structure of Paper •  3D surface estimation of newsprint from microscopic images

Shahram Hauck

Automated CtP Calibration System

•  Trapping formula based on reflectance spectra

•  ΔEab value instead of a percentage value

•  Surface effect and Ink penetration taken into account

•  Method to determine register variation

•  Simple but effective model using spectrophotometry tool

•  The results are close to those of Image processing tools, which are expensive
