What is sublimation ink and how does it work?

Sublimation ink is a dye-based ink that turns into gas when heated to 180-200°C, bonding directly with polyester fibers at the molecular level — so 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 won't crack, peel, or fade.

What fabrics can I print with sublimation ink?

Sublimation ink works best on 100% polyester and polyester-blend fabrics (minimum 60% polyester). It also prints on poly-coated hard surfaces including mugs, phone cases, aluminum panels, ceramic tiles, and keychains. It does not work on 100% cotton, silk, wool, or nylon — for those fabrics, use pigment or reactive dye inks instead.

How does INKBANK sublimation ink compare to other brands?

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.

• High color reproduction — Bright, accurate colors across polyester, coated metals, ceramics, and hard surfaces. Color consistency maintained during long production runs with minimal color drift.

• Excellent durability — Prints resist fading, peeling, and cracking through repeated washing. The ink bonds permanently with polyester fibers at the molecular level.

• Wide applicability — Sportswear, custom T-shirts, flags, personalized gifts, advertising signage, home decor, and poly-coated hard goods. One ink formulation covers multiple product categories.

• Stable batch-to-batch — ISO9001 quality management system governs every production batch. Same color on your first order and your 50th.
