<P>PROBLEM TO BE SOLVED: To provide an inkjet image having smudge resistance and durability as well as a favorable optical density. <P>SOLUTION: The first inkjet pen contains inkjet ink comprising the first liquid vehicle, a pigment color of 0.5 wt% to 6 wt% and a colloid suspension that contains 0.2 wt% to 15 wt% anionic or neural latex. The second inkjet pen contains a fixer composition comprising the second fluid vehicle of an effective amount and a cationic polymer of 0.2 wt% to 15 wt%, for example, poly (vinyl pyridine) salt, polyalkylaminoethyl acrylate, polyalkylaminoethyl methacrylate, poly (vinyl imidazole), polyethylene imine, polybiguanide and polyguanide. When applied to the substrate, a durable image of the smudge resistance with respect to the inkjet ink is generated by surface printing or basic printing of the above fixer composition. <P>COPYRIGHT: (C)2004,JPO
