Description
Genuine Fujifilm DX400W Black Ink Supply (250ml) — Part No. 16820995. Black is the channel that anchors every print the Frontier DX400W produces. It handles shadow depth, fine detail rendering, neutral density, and the overall contrast structure of an image. While it may deplete more slowly than Pink or Yellow in portrait-heavy environments, its quality has an outsized effect on the perceived sharpness and tonal depth of every single print — making genuine, on-spec Black ink non-negotiable for professional output.
Why Black Ink Quality Defines the Perceived Sharpness of Every Print
It's easy to think of Black ink as straightforward — after all, black is black. In professional photo printing, that assumption is where problems start. The DX400W's Black channel is responsible for more than just dark areas in a frame. It sets the maximum density point that the printer's tone curve is built around, controls how shadow detail is separated from pure black, and determines the crispness of fine lines and text.
Off-spec Black ink — whether from a third-party supplier or an incompatible formulation — shows up in ways that are immediately visible to trained eyes: shadows that block up rather than holding detail, a slight color cast in what should be neutral grays, and an overall softening of perceived image sharpness even in areas that have nothing to do with black ink directly. This happens because the DX400W's ICC profiles and tone curves are calibrated around the density and neutrality characteristics of genuine Fujifilm Black ink specifically.
Genuine Black ink (16820995) delivers the maximum density, neutral tone balance, and flow consistency the DX400W was designed for — in every print, every time.
Key Benefits
- Maximum shadow density and detail — Engineered to reach the full Dmax the DX400W is capable of, ensuring deep, rich shadows that hold fine detail rather than blocking up.
- Neutral tone balance — Genuine Fujifilm Black ink is formulated to be truly neutral, preventing the warm or cool color casts in gray areas that off-spec inks commonly introduce.
- Present in every print — Unlike specialty channels that dominate specific print types, Black contributes to virtually all images — making its consistency critical across high-volume production runs.
- Protects your printhead — Genuine Fujifilm ink maintains optimal viscosity and flow, reducing clog risk and costly service calls on high-precision inkjet heads.
- High-capacity 250ml soft pouch — Less frequent replacements in busy lab environments; eco-friendly design uses approximately 49% less plastic than rigid cartridges.

Frequently Asked Questions
The Black channel sets the maximum density point that the DX400W's tone curve is built around. When Black density or neutrality is off-spec, the printer's shadow separation changes — fine details in dark areas lose definition, and the overall contrast structure of the image softens. This is perceptible across the entire print, not just in areas that appear black.
Yes. This is one of the most common symptoms of third-party or incompatible Black ink in the DX400W. Neutral grays are produced by a precise balance of all six ink channels, but the Black channel anchors that balance. An ink that isn't formulated to the correct density or neutrality shifts the gray point warm or cool — a problem that is difficult to correct through profiling without affecting other colors.
In standard portrait and event photography environments, Black typically depletes more slowly than Pink, Magenta, or Yellow. However, it is used in every print, so it depletes steadily. In fine art, monochrome, or black-and-white printing workflows, Black consumption increases significantly relative to the color channels.
No. Replacing a depleted genuine Fujifilm Black pouch with a new genuine pouch of the same part number (16820995) does not require ICC profile changes or printer recalibration. The ink is formulated to match the factory calibration exactly.
Yes. Part number 16820995 is the current genuine Fujifilm Black ink supply for the Frontier DX400W series in the 250ml pouch format.
