  • Systems and methods for varying dye concentrations
    Patent number: 7971984
    Abstract: Systems and methods for varying dye loads. A fluid ejection apparatus includes a reservoir and an assembly. The reservoir stores ink with a first dye load and the assembly receives the ink with the first dye load from the reservoir. To obtain ink with higher dye load, the assembly evaporates a portion of the liquid solvent in the ink to obtain ink with a higher dye load.
    Type: Grant
