Inkjet printing methods and inkjet ink sets

This invention describes a way to print with inkjet printers using multiple inks that appear to be the same color and darkness but are chemically different. These distinct inks are precisely blended together inside the printer before being jetted onto the paper. The claims specifically focus on using pigmented, oil-based inks that share the same colorant and have a barely perceptible color difference, potentially varying in properties like surface tension.

Why it matters: Filed before advanced microfluidic control systems were common. The ability to precisely mix inks with different functional properties on-the-fly, while maintaining consistent color, is now more relevant for specialized printing applications.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedCustom ink mixing hardware, fluid control, software logic.
