Direct Pattern Control Halftoning of Neugebauer Primaries

Area of Science:

• Image Processing
• Color Science
• Printing Technology

Background:

• Halftoning is crucial for digital printing.
• Matrix-based halftoning faces challenges in co-optimizing multiple colorants.
• Increasing colorants complicates matrix selection and control.

Purpose of the Study:

• To present a novel halftoning method for multi-colorant printing.
• To overcome the complexities of co-optimizing matrices in traditional approaches.
• To simplify the halftoning process regardless of the number of colorants.

Main Methods:

• Utilizing a halftone area Neugebauer separation pipeline.
• Specifying local Neugebauer Primary use at each pixel.
• Employing a single halftone matrix for all colorants.

Main Results:

• Demonstration of a simplified halftoning process.
• Effective halftoning achieved irrespective of the number of colorants.
• Provably complete plane dependence of the resulting halftones.

Conclusions:

• The Neugebauer separation pipeline offers a robust solution for multi-colorant halftoning.
• This method simplifies complex co-optimization challenges.
• The approach ensures consistent and high-quality halftone reproduction.
