The Imaging Society of Japan

The image quality after printing the emulsion-containing ink on paper was found to be decreased as the amount of emulsion in the ink, that is, the number of particles in the droplet was larger, or as the particle size was increased. On the other, the image quality was higher when Tg of emulsion was higher. In addition, it was found that the product of the spreading area of ink droplets indicating the interaction with paper and the glossiness was a new index for predicting image density. Regarding the fixing property, it was found that when the amount of emulsion was the same as or larger than that of colorant, the entanglement of the polymer landed on the paper was thought to be improved and the fixing property was enhanced.
