In some cases the color balance of original data cannot be reproduced on inkjet media.This is the result of a difference between the original dot size and the dot size on the media. It is thought that one reason for this difference is the interaction between the ink and media, which is the dot forming processes such as ink droplet impaction, spreading and penetration.The coating layer of microporous inkjet media for photo printing consists mainly of pigment, binder, and a cationic ink fixative agent. The influences of these components on the dot formation were investigated.As a result, the color balance was determined by the dot size of each color ink, and a close relationship between the dot size and the ink penetration was observed. The cationic demand was the major property difference in each color ink, thus the amount of ink fixative agent was the determining factor.
