Sublimation Printing in Kampala
Ever seen a full-colour sports kit where the print seems to be part of the fabric — no edge, no peeling, no cracking? That's sublimation. Here's the quick version, then the deep version if you want it.
⚡ In 30 seconds
- What it is: Heat turns solid dye into gas that bonds into polyester — no ink layer on top.
- Why people love it: Full-colour, all-over prints. Never fades, cracks, or peels.
- Best on: Sports kits, cycling jerseys, mugs, caps, phone cases, metal plates.
- Not great for: 100% cotton. Sublimation requires polyester.
- Pricing in Kampala: Custom mugs from UGX 25,000; sports kits from UGX 45,000.
- Minimum order: 1 piece for mugs. 10+ for all-over sports kits.
- Turnaround: 2–5 working days.
Is sublimation right for you?
Yes — choose sublimation if...
- • Your garment is polyester or poly-rich
- • You want full-colour, photo-quality prints
- • You need all-over edge-to-edge coverage
- • You're printing sports kits, cycling jerseys, esports jerseys
- • You're branding mugs, caps, mousepads, phone cases
- • You want a zero hand-feel print
Skip sublimation if...
- • Your garment is 100% cotton (use DTF instead)
- • You need white ink on dark fabric
- • You want neon or metallic colours
- • You need prints on nylon, leather, or wool
- • You're printing 1 piece on a mixed-fabric item

How sublimation actually works
Imagine if the ink became part of the fabric instead of sitting on top of it. That's sublimation.
A solid dye is printed onto special paper. Then heat (around 190°C) turns that solid dye directly into a gas — it skips the liquid stage entirely. The gas penetrates the polyester fibres and locks in. When it cools, the dye is permanently fused inside the fabric. You can't feel it, because there's nothing on the surface.
The whole thing happens in three simple stages:
Print the transfer
Your design is printed mirrored onto special sublimation paper using disperse-dye ink.
Apply heat
Heat press at ~190°C turns the solid dye into gas. It penetrates the polyester.
Peel the paper
The dye has already bonded into the fabric. Nothing left on top — the print IS the fabric.
That's why sublimation prints feel like nothing. Because there's literally nothing on the surface — the colour is inside the fibre.
Why people in Kampala choose sublimation
Never fades. Never cracks.
The dye is inside the fibre. Nothing to fade, nothing to peel.
Full-colour, all-over prints
No colour limit. Cover the entire garment edge to edge with no visible border.
Zero hand feel
You can't feel the print at all. Stretch the fabric — the print stretches with it.
No setup fee
Unlike screen printing, there's no screen-making cost. Small runs are economical.
Great for hard surfaces too
Mugs, phone cases, metal plates, ceramic tiles — perfect for corporate gifts.
Photo-quality detail
Complex designs, gradients, and photos reproduce beautifully.

The science — why it works
Sublimation is a phase change from solid to gas — bypassing liquid entirely. This happens at approximately 180–200°C. The dye penetrates softened polyester fibres and bonds into the polymer structure. Once cooled, the dye is permanently locked inside.
Polyester compatibility
| Material | Polyester % | Works? |
|---|---|---|
| 100% Polyester | 100% | ✅ Perfect |
| Poly-rich blend | 65%+ | ✅ Good |
| 50/50 Cotton-Poly | 50% | ⚠️ Faded, vintage look |
| 100% Cotton | 0% | ❌ Doesn't work |
| Polymer-coated items | Coated | ✅ Perfect |
The process — step by step
1. Design prep: CMYK color mode, 300 DPI, mirrored. Colors look duller before transfer and vibrant after.
2. Print the transfer paper: Sublimation ink (disperse dyes) on special transfer paper, at 720–1440 DPI. Dry for 15–30 minutes.
3. Heat press setup: 180–200°C, 40–60 PSI, 30–60 seconds for flat substrates.
4. Transfer: Face-down transfer paper + heat + pressure. Dyes vaporise, penetrate, bond.
5. Peel: Hot peel (immediate) for speed; cold peel (wait 30–60s) for fine detail.
6. Post-press: Optional second press without paper to smooth surface.
Substrate temperature & time chart
| Substrate | Temp | Time |
|---|---|---|
| Polyester fabric | 190°C | 40s |
| Mugs (coated) | 180°C | 180s |
| Caps | 190°C | 45s |
| Metal plates | 190°C | 60s |
| Ceramic tiles | 200°C | 300s |
| Wood (coated) | 190°C | 60s |
Colour limitations
Sublimation has a smaller colour gamut than DTF or screen printing. Hard-to-hit colours:
- Pure reds — tend to shift orange
- Deep blacks — come out dark grey without heavy deposit
- Neon greens — impossible to reproduce accurately
- Metallic gold — impossible (no metallic pigment in sublimation ink)
Common problems and fixes
| Problem | Cause | Our Fix |
|---|---|---|
| Faded print | Low polyester %, low temp, short time | Poly-rich fabric, adjusted temp/time |
| Ghosting | Paper moved during press | Tape paper down, cold peel |
| Yellowing | Overheating, scorching fabric | Lower temp, shorter time |
| Mug cracks | Thermal shock | Cool gradually, no cold water |
| Uneven colour | Uneven pressure | Level press, check gauge |
Sublimation vs DTF vs Screen printing
| Factor | Sublimation | DTF | Screen |
|---|---|---|---|
| Fabric | Polyester only | Any | Any |
| Colours | Full CMYK | Full CMYK + white | 1–4 typically |
| Hand feel | Zero | Slight | Slight to thick |
| Setup fee | None | None | Per colour |
| Best for | Sports kits, mugs | Small runs, cotton | Bulk, bold |
Wash & care
- Wash inside out at 30–40°C
- No bleach or fabric softener
- Tumble dry low or hang dry
- Iron on reverse — never direct on the print
