摘要:
A method for improving the quality of printing processes involving black pixel depletion by printing composite ink in pixel spaces where a black pixel depletion process leaves unfilled pixel spaces. Black pixel depletion data are employed (for example, a depletion mask is inverted) to generate a composite printing mask which designates pixel spaces which are candidates for being filled in with a composite ink. In a preferred embodiment, edge pixels of black fill areas are excluded from the candidate pixels. In a preferred embodiment, the white pixel spaces are filled in by printing a plurality of different colored inks (e.g., cyan/magenta/yellow or cyan/magenta) within these unfilled pixel spaces. In a preferred embodiment, the composite printing mask additionally serves as an under/overprinting (UOP) map.

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.
