Method and apparatus for preventing color bleed in a multi-ink printing system
A method for controlling color bleed in multi-color thermal inkjet printing systems. Color bleed involves the migration of coloring agents between adjacent zones in a multi-color printed image on a substrate.

| description | A method for controlling color bleed in multi-color thermal inkjet printing systems. Color bleed involves the migration of coloring agents between adjacent zones in a multi-color printed image on a substrate. To control color bleed between any two ink compositions in a multi-ink system, at least one of the ink compositions will contain a precipitating agent (e.g. a multi-valent metal salt). The precipitating agent is designed to react with the coloring agent in the other ink composition of concern. As a result, when the two ink compositions come in contact, a precipitate is formed from the coloring agent in the other ink composition which prevents migration thereof and color bleed problems. This technique is applicable to printing systems containing two or more ink compositions, and enables distinct multi-color images to be produced without the problems normally caused by color bleed. |
