Description
Genuine Fujifilm DX400W Sky Blue Ink Supply (250ml) — Part No. 16821030. The dedicated Sky Blue channel in the Frontier DX400W's 6-ink system is what separates a flat, oversaturated blue sky from one that looks real. This 250ml pouch is engineered exclusively for the DX400W dry lab and is the only ink that can reproduce the smooth, grain-free tonal transitions that cyan alone cannot achieve.
Why Sky Blue Is Not the Same as Cyan
The Fujifilm Frontier DX400W uses a proprietary 6-color ink system that adds Sky Blue (SB) and Pink as two extended gamut channels beyond the standard CMYK set. Sky Blue handles the light-toned blue spectrum — the areas where cyan at reduced density would print with unwanted grain or hue shifts. The result is smoother skies, softer water reflections, and cleaner highlight transitions in outdoor and portrait photography. If you're printing without genuine Sky Blue ink, you're not getting the output the DX400W was designed to produce.
Key Benefits
- Eliminates grain in light blue zones — Designed specifically for sky gradients, water, and soft backgrounds where standard cyan would introduce noise or color casts.
- Precise color matching — Formulated to Fujifilm's ICC profile specifications for the DX400W, so your color management stays accurate out of the box.
- Protects your printhead — Genuine Fujifilm ink maintains optimal viscosity and flow properties, reducing the risk of clogging and expensive service calls.
- High-capacity 250ml soft pouch — Reduces replacement frequency in busy photo labs, studios, and event printing environments; eco-friendly design uses approximately 49% less plastic than rigid cartridges.
- Drop-in installation — Designed to be recognized immediately by the DX400W's ink management system with no recalibration required.

Frequently Asked Questions
Third-party inks are not formulated to Fujifilm's viscosity or color specifications for the DX400W. Using them can cause printhead clogs, color inaccuracies, and may void your service agreement. Genuine Fujifilm ink is the safest and most cost-effective choice long-term.
Cyan is a primary CMYK color used across the full tonal range. Sky Blue is a lighter, extended-gamut channel that handles soft blue highlights — areas where cyan at low density would appear grainy or slightly off-hue. The two channels work together but serve different parts of the color space.
The DX400W's ink management system tracks remaining ink levels and will display a low-ink alert on the operator panel before the pouch is fully empty, giving you time to order a replacement without interrupting production.
No. Genuine Fujifilm DX400W inks are pre-calibrated to work with the printer's factory ICC profiles. No additional profile configuration is needed when replacing with the same genuine ink.
Yes. Part number 16821030 is the current genuine Fujifilm Sky Blue ink supply for the Frontier DX400W series in the 250ml pouch format.
