Solution Overview

Problem

The CMYK color system used in digital printing struggles to accurately reproduce warm wood decors in the furniture and laminate flooring industry, particularly failing to produce shades of brown effectively, leading to insufficient color representation and high costs due to the use of specific pigments like PR254 and PY151.

Innovation Solution

A digital printing ink composition using a CRYK system with modified color components, replacing magenta with a mixture of red and yellow pigments, and using a combination of yellow and red pigments to expand the color space towards orange-red, allowing for better reproduction of warm tones without metamerism issues, and reducing costs by using alternative pigments like PY181 and PR207.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the CMYK color system is used for digital printing, then the printing process is simple and widely applicable, but the reproduction of warm wood decors and brown shades is insufficient

Engineering Contradiction:
