Sublimation gets oversold and misordered in equal measure. Understand the chemistry and its two hard constraints, and it becomes obvious when dye-sub wins outright and when embroidery, screen print or heat transfer is the smarter call.

How dye-sublimation actually works

In sublimation, the design is first printed with disperse dyes onto transfer paper, then heat and pressure (around 200 °C) convert that dye directly from solid to gas. The gas penetrates and bonds with polyester fibres, which open under heat and lock the colour in as they cool. Because the dye becomes part of the fibre rather than sitting on it, there is no hand-feel, no cracking and no peeling — the print cannot be felt and will not wash off. This is also why sublimation only works on polyester, or polyester-coated surfaces.

The two hard constraints

Sublimation has two non-negotiable limits, and most failed sublimation jobs ignore one of them. First, the substrate must be polyester (ideally 100%, certainly 60%+) — the dye has nothing to bond to on cotton, so a cotton tee cannot be sublimated. Second, it works by adding colour, so it needs a light base — you cannot sublimate a light design onto a dark garment, and white areas of the design are simply where the fabric shows through. If your garment must be cotton, or dark with a light logo, sublimation is the wrong method.

Where sublimation is unbeatable

When the constraints are met, sublimation does things no other method can:

For a dark cotton jacket with a two-colour logo, screen print or embroidery wins. For a polyester sports shirt with an all-over team graphic, nothing else comes close.

When to choose dye-sub

Reach for sublimation when the garment is polyester and light-coloured, the design is full-colour, photographic or all-over, and hand-feel or stretch matters — sports kit, cycling wear, performance polos, mascots, and event apparel with complex artwork. Because setup is cheap (no screens, no digitising), it also suits small runs and one-offs where screen-print setup would not amortise. Skip it the moment the spec calls for cotton, dark grounds with light logos, or a simple one-colour mark that embroidery would render more cheaply and with a premium feel.
