Ink-jet printing methods and systems providing improved image durability

A method for printing durable ink-jet ink images, comprising steps of:

• a) applying a cationic fixer composition to a media substrate;
• b) jetting an ink-jet ink composition onto the fixer composition that has been applied to the media substrate, said ink-jet ink including an anionic colorant;
• and
• c) jetting an anionic polymer overcoat composition onto the ink-jet ink composition that has been jetted onto the fixer composition.

A durable printed image, comprising:

• a) a media substrate;
• b) a cationic fixer composition jetted on the media substrate as a first printed layer;
• c) an ink-jet ink composition jetted on the fixer composition as a second printed layer, said ink-jet ink including an anionic colorant;
• and
• d) an anionic polymer overcoat composition jetted on the ink-jet ink composition as a third printed layer.
