We investigated water-based ink-jet inks which fix quickly on plain paper. Ink-jet inks have liquid components which evaporate slowly to prevent the print head nozzles from clogging. The fixing time of these inks is too long for printing on plain paper. Inks cannot penetrate paper which contains a sizing agent, which increases the paper's resistance to liquids. The most widely used sizing agent is rosin. We attempted to shorten fixing time by including in the ink, a component for dissolving rosin. The glycols used in the ink are useful because they evaporate slowly. We determined the relationship between the solubility of the ink for sizing agents, rosin, and the time needed for fixing and penetration. The higher the solubility of a glycol for rosin, the faster the penetration of the ink containing it. Hexylene glycol dissolves rosin over 70 wt%, and ink containing over 15 wt% hexylene glycol penetrated plain paper within 5 seconds.
