The CMYK to CMYK mapping preserving the black channel is a method to solve the problem in standard ICC color management that lacks the capability of preserving the K channel for printing CMYK contents. While the method has been successfully used for digital commercial printing, limitations and areas for improvement are found. To address these problems in generating CMYK re-rendering tables, an alternative method is developed. The K usage and total ink usage are optimized in a color separation step. Instead of preserving the K channel globally, it preserves K-only gray contents and maps other colors by optimizing the print quality and ink usage. Experiments verify that the method significantly improves the print quality.
