摘要：
Dispersibility of thickener is constant for every lot and viscosity difference is little. Fine bubbles existing in the thicker in ink follower are removed. A step of homogenizing the thickener at any temperature within a range of 40° C. to 130° C. is included. Preferably, a step of homogenizing the thickener at any temperature within a range of 100° C. to 130° C. is included.
