Sublimation ink is a dye-based ink that turns into gas when heated to 190-200°C — bonding directly with polyester fibers at the molecular level. The print becomes part of the fabric, not a layer on top. It is used on polyester fabrics, coated metals, ceramics, and poly-coated hard surfaces like mugs and phone cases. The result: vibrant, permanent prints that will not crack, peel, or fade.
| ✓ Works Well | ✗ Does Not Work |
|---|---|
| 100% Polyester fabrics | 100% Cotton |
| Polyester blends (min. 60% polyester) | Silk, wool, nylon |
| Poly-coated mugs, phone cases, aluminum panels | Uncoated natural surfaces |
| Coated ceramic tiles, keychains, MDF | Dark-colored fabrics (use DTF instead) |

INKBANK sublimation ink delivers 4-5 color fastness after 100+ industrial washes, transfers at 200-220°C in 35-60 seconds, and is batch-tested for color consistency across 40,000 tons of annual production. Here is what that means for your production line:
Color Consistency
Spectrophotometer-verified per batch
ΔE < 2.0 between production runs. Your 50th order matches your first. No color drift during long print runs.
Printhead Safety
Nano-filtered to D90 < 250nm
Tested on 500+ devices across Epson, Kyocera, and Ricoh platforms. No nozzle dropout after 48-hour idle.
Batch Documentation
QC data sheet with every shipment
Viscosity, surface tension, particle size D50/D90, pH, and color density. Full traceability from production batch to your door.
Multi-Substrate
One formulation, many products
Sportswear, flags, home decor, promotional gifts, signage, and poly-coated hard goods. Fewer SKUs, simpler inventory.
A supplier's website can claim anything. These five questions separate a manufacturer from a middleman. A real manufacturer answers them before you finish asking.
| Ask the Supplier | What a Real Manufacturer Answers |
|---|---|
| "Can I see your R&D lab — live on video?" | "Here is a link. Our lead chemist will walk you through." If they hesitate, they do not have a lab. |
| "Send me the QC data sheet for the batch my sample came from." | PDF arrives in 10 minutes: viscosity, surface tension, particle size D50/D90, pH, color density. Five parameters, one page. |
| "How many test printers do you own? Which printhead models?" | "We run 500+ devices — Epson I3200/I1600, DX5/DX7, Kyocera KJ4, Ricoh GEN5/GEN6, Konica 1024i." A number under 20 is a red flag. |
| "What are your certification numbers? Can I verify them online?" | Numbers provided immediately — verifiable on oeko-tex.com and the ZDHC Gateway. If they will not give you a certificate number, the logo on their site is decoration. |
| "Can you reference a customer in my region?" | "We supply a sportswear manufacturer in [your region] producing [X] garments/month since [year]." Even anonymized, it proves they ship where you are. |

Not sure whether to use pigment or sublimation? The table below covers the key differences. Still uncertain? Read the full DTF vs DTG vs Sublimation comparison →
| Feature | Pigment Ink | Sublimation Ink |
|---|---|---|
| Best for | Cotton, blends, paper, wide range | Polyester fabrics & poly-coated hard goods |
| How it works | Pigment particles sit on fabric surface | Dye turns to gas → bonds into the fiber |
| Color vibrancy | Rich colors, excellent longevity | Vibrant & saturated on polyester |
| Wash fastness | Good — withstands normal washing | Excellent — color becomes part of the fabric |
| Hand feel | Slight texture on fabric surface | Zero hand feel — ink is inside the fiber |
| Heat requirement | Air dry or low-heat cure | Requires 190-200°C heat press |

INKBANK ultra-high concentration sublimation ink costs USD 0.08–0.15/m² depending on coverage and printer settings. The concentrated formula covers 1.5× more fabric per liter than standard sublimation inks, reducing total ink cost by 30–40%. At 80–120 m² per liter coverage, this is the lowest per-square-meter cost among all digital textile ink types.
INKBANK sublimation ink is formulated for Epson i3200, Epson S3200, Kyocera KJ4A, Kyocera KJ4B, and Ricoh Gen5 industrial printheads. Each formulation is tuned to the specific head's viscosity and jetting frequency requirements. Free compatibility testing is available — send your printhead model for a custom ink recommendation within 48 hours.
Yes. INKBANK sublimation ink is certified OEKO-TEX ECO PASSPORT (chemical safety for textiles) and GOTS 7.0 (Global Organic Textile Standard). These certifications meet EU textile brand requirements and eliminate customs friction for European importers. Full REACH compliance and ZDHC MRSL Level 3 certification also apply across all INKBANK ink lines.
INKBANK sublimation ink has a 12-month shelf life when stored in sealed containers at 5–35°C away from direct sunlight. Dye-based sublimation inks naturally degrade more slowly than pigment-based inks. Every shipment includes a batch-level Certificate of Analysis with viscosity and particle size data. Once opened, use within 3–6 months depending on printer environment.
Last updated: June 2026 | INKBANK R&D Team | 50+ patents. 16 labs. 500+ test devices.
