Abstract

Today, ICC profile is the de-facto standard for color reproduction between different color devices in the digital printing industry. However, there is a problem for pure black color reproduction while using a CMYK profile due to the transformation of black color based on spectral data in the profile. The black color is usually printed in gray instead. This paper addresses this problem, presents a Black Point Compensation (BPC) method and provides experimental results. The method can significantly improve the quality of black reproduction, and has been successfully implemented in a commercial color management software.
