HP FB794 Aftermarket UV Ink for HP Scitex FB550 & FB750

HP FB794 Aftermarket UV Ink

HP FB794 is the UV-curable ink platform engineered for the HP Scitex FB550 and HP Scitex FB750 flatbed printers — production UV machines running rigid-substrate work across sign shops, P-O-P printers, exhibit and trade-show shops, and industrial graphics shops in Florida and the Southeastern US. Our aftermarket HP FB794 UV ink is print-tested for color match and printhead compatibility on these flatbed presses, supplied on an inquiry basis to B2B production print shops.

This page is a quote request page. Tell us the colors and the quantity, and our service team will reply with current aftermarket HP FB794 pricing, lead time and shipping ETA. UV ink consumption on flatbed presses is heavier than on roll-to-roll latex machines, so most FB550 and FB750 shops settle into a recurring monthly supply cadence rather than one-off orders.

Compatible HP Scitex flatbed printers — full model breakdown

HP FB794 is the current-generation UV ink platform for two production flatbed printers in HP’s Scitex lineup. The FB550 and FB750 share the same ink architecture; the difference between them is build size and throughput, not consumables.

HP Scitex FB550

The Scitex FB550 is HP’s mid-volume production UV flatbed — 1.65 m × 3.20 m bed, built for rigid-substrate work including foam board, corrugated, acrylic, PVC, wood, and direct-to-rigid signage. The FB550 runs the FB794 6-color CMYK + Light Cyan + Light Magenta cartridge set as standard. White ink is an optional upgrade via the HP Scitex FB550 White Ink Upgrade Kit; with the kit installed, the White cartridge replaces the Light Cyan and Light Magenta channels. Tampa Bay applications: trade-show graphics, retail P-O-P, architectural signage, custom packaging prototypes, point-of-purchase displays.

HP Scitex FB750

The Scitex FB750 is the higher-throughput sibling in the same 1.65 m × 3.20 m bed class — same FB794 6-color cartridge footprint, faster carriage and higher production duty cycle. Same White ink option via the FB750 White Ink Upgrade Kit. Production FB750 shops in Tampa Bay typically cycle through CMYK cartridges every few weeks at full production load; Light Cyan and Light Magenta consume slower unless the shop runs heavy photographic content. White ink consumption depends entirely on whether the shop runs White-backed translucent or White-underprint workflows.

HP FB794 cartridge SKU cross-reference

For shops searching by exact SKU, here is the HP FB794 cartridge map. Our aftermarket HP FB794 cartridges are matched to each OEM slot position on the FB550 and FB750 ink bay; the labels and packaging are our own, the print system reads them as the correct slot.

Color / function	OEM HP SKU reference	Volume	Aftermarket replacement
Cyan	G0Y93A	3 L	Aftermarket HP FB794 Cyan
Magenta	HP FB794 Magenta	3 L	Aftermarket HP FB794 Magenta
Yellow	G0Y95A	3 L	Aftermarket HP FB794 Yellow
Black	HP FB794 Black	3 L	Aftermarket HP FB794 Black

Buyers who arrive searching for a specific SKU — for example “G0Y93A cyan FB794” or “G0Y95A yellow” — land in the right place. Tell us the SKUs you’re ordering in the form and we’ll confirm aftermarket fit before quoting.

HP FB794 vs HP FB250 — which one your Scitex actually uses

The single most common HP Scitex flatbed ink mix-up is FB794 vs FB250. They are both 3-L UV-curable cartridge platforms for HP Scitex flatbed printers, but they target different machine generations. Here’s the clean breakdown:

• HP Scitex FB500 — HP FB250 only. Earlier-generation flatbed; uses the FB250 platform (CH216A through CH221A SKU range).
• HP Scitex FB700 — HP FB250 only. Same earlier-generation FB250 ink architecture.
• HP Scitex FB550 — HP FB794 primary, HP FB250 cross-compatible. The FB550 ships configured for FB794, but HP-published compatibility documentation confirms FB250 inks can be mixed with FB794 on the same FB550 press.
• HP Scitex FB750 — HP FB794 primary, HP FB250 cross-compatible. Same cross-compatibility as the FB550.
• HP Scitex FB950 — HP FB250. Production-class flatbed using the FB250 platform.

If you run a fleet that includes both FB500/FB700 and FB550/FB750 machines, this cross-compatibility is operationally important — you can standardize on FB250 across the fleet (one ink line, simpler stocking), or run FB794 on the newer machines and FB250 on the older ones. Most Tampa Bay flatbed shops we supply settle on one platform per press to keep color consistency tight; cross-compatibility is the fallback for stock-out events, not the daily SOP.

If you’re unsure which platform your machine is configured for, our UV flatbed service team can confirm by serial number and ink-system configuration before we quote. See our HP FB250 ink page if you also run FB500, FB700 or FB950 machines.

Symptom-driven entry — when shops actually order HP FB794

Most HP FB794 buyers don’t arrive because they’re shopping ink. They arrive because an FB550 or FB750 hit a UV-supply event. The most common entry points:

• Color-out on a production rigid run. A specific color (often Magenta or Yellow first on saturated retail P-O-P or architectural signage) drops below the printer’s low-ink threshold mid-job. Flatbed shops typically backstop a full cartridge per CMYK color; recurring monthly supply prevents this entirely.
• White ink degradation. White ink has a 6-month manufacturer shelf life — half the color ink window — and pigment settling in unused White cartridges is a real failure mode. If your White output is showing density loss, head-to-substrate inconsistency, or banding on White-underprint jobs, the cartridge age and agitation discipline are the first things to check before the printhead.
• UV printhead clogs. UV ink cures on light, including stray ambient light reaching the printhead nozzles during long idle periods. Clogs are mostly a maintenance and idle-time issue, not an ink-quality issue — but contaminated or expired cartridges accelerate clog frequency. If clogs are increasing, check the cartridge stock-rotation discipline.
• Banding on rigid substrates. Banding is usually printhead-side or substrate-handling-side, not ink-side, but failing ink shelf life can contribute. If banding persists after printhead service, our UV flatbed repair team can diagnose before you order more ink.
• White Ink Upgrade Kit installation. If you’re adding White ink capability to an FB550 or FB750, this is a natural moment to validate aftermarket FB794 supply across the full cartridge set. Quote both standard CMYK and White in one inquiry.
• Switching from FB500/FB700 to FB550/FB750. Existing FB250 stock works on the FB550/FB750 thanks to cross-compatibility — but for color consistency on a single press, most shops standardize on FB794 once they’re on the newer machine. Talk to us before you stock the transition.

Aftermarket HP FB794 vs OEM HP FB794 — the honest read

UV flatbed shops evaluate ink switches more carefully than roll-to-roll latex shops because UV ink chemistry interacts with substrate adhesion, cure profile, and printhead longevity. Here’s the read we give every FB550 / FB750 shop evaluating a switch:

• Color accuracy. Our aftermarket HP FB794 lots are color-tested against the OEM HP UV color gamut. Print-tested delta-E typically falls within production-acceptable range for retail P-O-P, architectural signage, exhibit graphics, and rigid-substrate sign work. For brand-color-critical packaging prototypes or Pantone-tight retail brand work, we recommend test prints on your specific substrate before committing to a recurring order.
• Printhead compatibility. The FB550 and FB750 use a piezoelectric inkjet head specifically tuned to the FB794 UV ink rheology. Our aftermarket FB794 chemistry is matched to the printhead’s drop-volume targeting and firing characteristics — viscosity, surface tension, and pigment particle size all spec to the OEM range.
• UV cure profile. The FB550 and FB750 UV cure lamps are tuned to the FB794 photoinitiator package. Aftermarket FB794 lots use a matched photoinitiator system so cure energy and lamp dwell-time settings stay at OEM defaults; substrate adhesion test results stay consistent.
• Chip programming and slot reporting. Aftermarket FB794 cartridges carry compatible chip programming so the FB550/FB750 reads them as the correct slot and reports ink levels normally. The cartridge bay treats them the same as OEM cartridges.
• Cross-compatibility with FB250 stays intact. If your shop runs a mixed FB250/FB794 stocking pattern, aftermarket FB794 stays cross-compatible with FB250 on the FB550/FB750 — same HP-published compatibility envelope.
• ICC profile compatibility. Aftermarket FB794 is ICC profile compatible with standard HP Scitex UV media profiles. Most shops run existing substrate profiles unchanged; for tighter color-critical work, a one-time re-profile against a fresh aftermarket lot tightens delta-E further on the specific substrates that matter most.
• Cost-per-square-foot on UV. UV ink price-per-square-foot is the line item that gets attention on a production flatbed — heavier coverage and rigid-substrate consumption add up faster than roll-to-roll latex spend. Aftermarket FB794 materially moves that number. Exact figures depend on your monthly substrate volume and coverage profile, which we’ll size in the quote.

Shelf life and storage — UV ink-specific handling

UV ink has tighter shelf life and storage requirements than latex or eco-solvent ink. The discipline matters because expired or improperly stored UV ink fails in ways that look like printhead problems but aren’t.

• Color cartridge shelf life: 12 months from date of manufacture (OEM reference, matched on aftermarket lots).
• White cartridge shelf life: 6 months from date of manufacture — half the color window. White pigment settles faster and the photoinitiator system degrades faster on White formulations.
• Storage temperature: 5–40°C, cool and dry. Hot Florida storage rooms during summer are a real risk — UV cartridges left in non-climate-controlled storage above 40°C lose shelf life rapidly.
• Light exposure: UV ink is photoinitiator-based; ambient UV light (including indirect sunlight through windows) can pre-cure ink in cartridges over time. Store cartridges in original packaging until use.
• Cartridge agitation: White cartridges in particular need pre-use shaking to redistribute settled pigment. Follow HP’s published agitation procedure before seating a fresh White cartridge.

Stocking discipline for production flatbed shops: FIFO the bulk supply bay so the oldest cartridge feeds first. Don’t over-stock White — 6-month shelf life means buying more White than you’ll use in 6 months is wasted spend.

Recurring supply cadence for FB550 / FB750 production

Production FB550 and FB750 shops in Tampa Bay typically settle into one of three supply patterns:

• Monthly recurring CMYK + quarterly Light + White on-demand. Full CMYK monthly; Light Cyan and Light Magenta on a slower quarterly cadence; White ordered on-demand when a White-workflow job is committed. Best for shops with consistent rigid-substrate output and occasional White jobs.
• Six-week recurring full set. Full 6-color CMYK + Lc + Lm every six weeks. Best for shops with predictable but not daily flatbed production.
• Monthly White-workflow shops. Shops running steady White-underprint or White-backed translucent work cycle White at the same monthly cadence as CMYK. White’s 6-month shelf life sets the ceiling — don’t carry more than 5 months of White stock at the shop.

Note your typical monthly substrate volume or square-footage in the inquiry form and our service team will quote the right cadence sized to your output.
