The waterborne pigment red 122 dispersions with different particle size were prepared by phase separation technique, and follow prepared the inkjet printing inks. The effects of particle size on absorbance and the crystal of pigment were measured, and also the color properties of textile which printing using these inks. The results showed that the absorbance was the lowest and printing performance the pigmented ink with particle size 110.8nm was the best among these three pigmented inks. The K/S values of printing cotton fabrics showed that the pigmented ink with small particle size could import cotton fabrics much higher color depth. The rubbing fastness of cotton fabrics printed by the pigmented ink with particle size 110.8nm was superior to the other pigmented inks.
