摘要: Current color-printing technologies may use three or more inks, e.g., CMY, CMYK, CMYKcm, CMYKGO, CMYKRGB. When the number of inks exceeds three, there is usual color-management one-to-many mapping problem. Because spectral properties many modern are optimized for maximum color gamut and in some cases, black ink not be used pictorial images, prints have poor constancy. Changes lighting dramatically change balance, particularly neutrals. An algorithm was developed multi-ink printing which problem overcome by selecting combinations with best constancy between illuminants F11 D50. The tested using a pigmented-ink inkjet proofing printer. CMYKGO color-separated this were compared generic ICC profile CMYKcm prints. CMYK common to both new improved significantly.
