DTG vs Sublimation: Which Is Right for Your Custom Apparel?

Question: Should I use DTG printing or sublimation for my custom apparel in South Africa?

Answer: The decision is straightforward once you know your fabric: 100% polyester → sublimation. 100% cotton → DTG or screen. Polyester blends → DTF (not DTG or sublimation). That single fact resolves 90% of printing method debates.

The Fabric Type Rule#

Fabric Type × Design Type = Right Method

<AcademyQuote>There is no such thing as a universal best printing method. The "best" method depends entirely on what garment you are printing — and the fabric composition is non-negotiable.</AcademyQuote>

DTG vs Sublimation: Side-by-Side Comparison#

How Sublimation Works#

Sublimation is a chemical process where heat and pressure cause solid dye particles to become gas and bond directly with polyester fibres. The ink becomes part of the fabric rather than sitting on top of it.

The Sublimation Process#

1. Design is printed in mirror image onto sublimation transfer paper using sublimation inks
2. The printed paper is placed against the polyester garment
3. A heat press applies 180–200°C with significant pressure for 30–60 seconds
4. The heat causes the sublimation inks to turn from solid to gas
5. The gas penetrates the polyester fibres and bonds permanently
6. The paper is removed — the design is now part of the fabric

Why Sublimation Requires 100% Polyester#

The chemical bonding only works with polyester fibres. On cotton, the gas dissipates into the air or bonds improperly — resulting in faded, washed-out prints that feel stiff. Sublimation on cotton is a recipe for disappointment.

<AcademyProTip>When sourcing garments for sublimation, specify "100% polyester" explicitly to your supplier. Some "sports" or "activewear" garments may be 65/35 blends — which will not sublimate properly.</AcademyProTip>

When Sublimation Excels#

Sportswear and Activewear This is sublimation's natural home. Polyester sports jerseys, running tops, cycling shorts, and gym wear are almost always sublimation-printed. The prints:

• 1Do not crack or peel, even with heavy stretching
• 2Remain vibrant after hundreds of washes
• 3Allow full-print designs (the whole garment can be decorated)
• 4Weigh almost nothing (no ink layer on top of fabric)

Vivid, Full-Colour Designs on White or Light Polyester Sublimation produces the most vibrant full-colour prints possible on polyester. If you want photographic-quality prints, all-over garment designs, or complex colour gradients on polyester — sublimation is the answer.

SA Sportswear Market Context South Africa's sportswear market — from amateur soccer clubs to corporate running events — is enormous. Sublimation dominates because:

• 1Team kit requires multiple colours and sponsor logos (no screen setup needed)
• 2Full-print designs create premium perceived value
• 3The durability matches the physical demands of SA sports
• 4Bulk orders (20–50 kits) make sublimation cost-effective

How DTG Works#

DTG (Direct-to-Garment) uses modified inkjet technology to spray water-based inks directly onto cotton garments. The ink soaks into the fibres, similar to how a tattoo inks skin.

The DTG Process#

1. Garment is loaded onto the printer's flatbed
2. Pre-treatment may be applied to dark garments (white underbase)
3. The DTG printer deposits ink directly onto the fabric surface
4. Ink is cured (typically with a heat press or conveyor dryer)
5. The print is complete — soft-hand finish on cotton

Why DTG Prefers Cotton#

Cotton fibres are porous and absorb water-based inks readily, producing a soft, comfortable print. The cotton fibres themselves become part of the image — the print feels like it is part of the garment.

When DTG Excels#

Cotton T-Shirts with Full-Colour Designs DTG is the default choice for printing photographs, complex full-colour illustrations, or detailed designs on cotton. No screen setup means even a single shirt with a complex design is economically viable.

Small Orders (1–20 Units) DTG has no per-screen setup cost, making it ideal for small runs of fully customised garments. You can print 5 unique designs on 5 shirts each — at the same per-unit cost as 25 identical shirts.

Retail and Premium Garments The soft hand feel of DTG makes it popular for boutique, fashion, and premium apparel brands. The print does not have the heavier texture of screen print, which is important for fashion-forward designs.

The Mixed Fabric Problem: DTF#

What about polyester/cotton blends? Neither sublimation nor DTG works well on them. The solution is DTF (Direct-to-Film) — a transfer printing process where the design is printed onto a special film and then heat-pressed onto any fabric type.

DTF: The Universal Transfer Method#

DTF prints work on:

• 1100% cotton ✓
• 2100% polyester ✓
• 3Cotton/poly blends ✓
• 4Nylon ✓
• 5Acrylic ✓
• 6Dark garments ✓

DTF has a slight plastic-like feel that diminishes with washing, but it is the most versatile apparel printing method available.
