The digital ceramic printing technology uses ceramic materials tprint out the digital image and requires establishing the program for color management through the effective operation of the digital equipment, optimal ink property and interchangeability among materials. This study eliminates the ZnO or the case of reaction between the ink and glaze found in the previous study and replaces it with CaO-based frit to complement the problem. The color management of the digital ceramic printing consists of 4-channel inks including the blue, hot-pink, yellow and black for the ceramic process in the Create a New Mode phase. The output density in a single channel is optimized by the ink restriction, linearization and ink limit to confirm the excellent color phase and the stable color mix is reproduced under 200% of the ink output density. Besides, in this study, the ink volume of the hot-pink and yellow inks was increased to 100% with the color loss and weak color force under the low output density to confirm the output density of the ink mix and the profile of 2 conditions was established. The output image with the application of 2 profiles shows stable reproduction under the optimal output density and the color gamut expansion. The image with the maximum volume of the hot-pink and yellow shows difficulty in identifying fine tone change due to the strong contrast. Therefore, it is thought that the profile considering the color and tone of the output image should be applied to reduce the color losses. Therefore, the color control through the 4-channel (blue, hot-pink, yellow, black) inks shall expand the color gamut by setting up various profiles depending on the color and tone and applying the standard spot color like green, red, purple and orange.
