Description
Genuine Fujifilm DX400W Cyan Ink Supply (250ml) — Part No. 16821004. Cyan is one of the four CMYK foundation channels in the Frontier DX400W's 6-ink system and one of the most versatile. It contributes to blues, greens, neutrals, and shadow tones across virtually every type of photography. In the DX400W specifically, Cyan works in close partnership with the dedicated Sky Blue channel — handling the saturated end of the blue spectrum while Sky Blue takes over in the lighter, more delicate tonal ranges where standard cyan would produce grain.
Cyan and Sky Blue: How the DX400W Handles Blues Differently
Standard 4-color CMYK printers rely on Cyan alone for the entire blue spectrum — from deep ocean tones all the way to a pale afternoon sky. The limitation is that Cyan at low density becomes grainy and slightly greenish, which is exactly where light sky and water tones live. Landscape and travel photographers printing on standard CMYK systems know this problem well.
The Fujifilm Frontier DX400W resolves it by adding Sky Blue (SB) as a dedicated sixth channel alongside Cyan. Cyan handles the rich, saturated blue range — deep sky, ocean water, dark foliage shadows, and the blue-toned shadows in portraits. Sky Blue takes over in the lighter register — pale skies, soft water highlights, clean backgrounds, and any area where diluted Cyan would introduce visible grain or an unwanted green cast.
This means Cyan on the DX400W is precision-tuned for its specific portion of the color space. Genuine Fujifilm Cyan ink (16821004) is formulated to hold up its half of that partnership accurately — keeping deep blues rich and saturated while staying in balance with the Sky Blue channel across the full gradient.
Key Benefits
- Accurate blues, greens, and neutrals — Cyan contributes to a wide range of mixed colors beyond pure blue: forest greens, teal tones, cool-neutral shadows, and gray balance across the entire print.
- Optimized for the Cyan/Sky Blue dual-channel system — Genuine ink maintains the precise color handoff between Cyan and Sky Blue that the DX400W's color engine is calibrated for.
- Critical for landscape and outdoor photography — Deep skies, water, and foliage all depend heavily on Cyan channel accuracy for rich, saturated output.
- 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
Cyan handles the saturated, mid-to-dark blue range — rich skies, deep ocean tones, foliage shadows, and cool neutral shadows in portraits. Sky Blue handles the lighter, softer blue register where Cyan at low density would appear grainy or slightly greenish. Together they give the DX400W a far smoother and more accurate blue gradient than any standard CMYK system can achieve.
Cyan is a primary subtractive color that participates in almost all color mixing. It combines with Yellow to produce greens, with Magenta to produce purples and cool reds, and with both to produce a wide range of neutral and shadow tones. An off-spec Cyan shifts all of those mixed colors simultaneously — which is why accurate Cyan ink is fundamental to overall print quality, not just blue reproduction.
Third-party inks are not formulated to Fujifilm's specifications for this printer. Off-spec Cyan is a common cause of green casts in neutral tones and color fringing in blue-to-sky gradients — problems that are difficult to correct through profiling alone. Genuine ink is the lower-risk option over the life of the printer and printhead.
No. Replacing a depleted genuine Fujifilm Cyan pouch with a new genuine pouch of the same part number (16821004) does not require ICC profile changes or printer recalibration. The ink is formulated to match the factory calibration exactly.
Yes. Part number 16821004 is the current genuine Fujifilm Cyan ink supply for the Frontier DX400W series in the 250ml pouch format.
