Start with the artwork and substrate
Decoration is a material process, not a visual filter applied to a mockup. The same graphic can behave differently on a cotton T-shirt, a textured fleece and a lightweight polyester jersey. Before choosing a method, identify the fabric, artwork dimensions, colour count, fine details, expected order pattern and acceptable surface feel. Include the likely care routine and whether repeat orders must match an earlier batch.
Ask a supplier to explain the constraints of the exact combination. Minimum line thickness, small lettering and colour reproduction depend on the equipment, consumables and substrate. Universal numerical rules are rarely a substitute for a representative test. Where an identity has fine details, use an approved production variant rather than allowing a supplier to simplify the mark without review.
| Method | Often useful for | Check before approval |
|---|---|---|
| Screen printing | Repeated graphics with controlled ink colours | Opacity, registration, curing and hand feel |
| Embroidery | Compact marks with a stitched finish | Digitisation, density, puckering and small text |
| Dye sublimation | All-over graphics on suitable polyester | Fabric compatibility, colour and panel alignment |
| Heat-applied transfers | Names, numbers and flexible artwork changes | Adhesion, migration, stretch and press marks |
Screen printing needs controlled preparation
Screen printing deposits ink through a prepared mesh. It can produce a deliberate, consistent appearance, but the result depends on more than the chosen colour. Ink system, mesh, underbase, print order and curing conditions all influence opacity, edge quality and feel. Dark garments may need an underbase, which can change both the visual result and the thickness of the print.
Review separations and registration where colours meet. Ask how the supplier checks that the ink has been cured according to its technical requirements. A dry surface is not proof of a correctly cured print. Test a finished example through the agreed care routine, and inspect cracking, loss of adhesion and colour change. Keep the approval tied to the specified garment rather than to an unrelated sample shirt.
Embroidery requires a stitch interpretation
An embroidery machine does not use a vector logo as a complete stitch plan. Digitisation determines stitch types, order, density, underlay and compensation. A supplier may need to adjust very small lettering or narrow gaps, but those changes should be approved as an identity decision. Ask for a stitch-out on comparable material and then review a sample on the intended garment.
Look for puckering, unstable edges, excessive stiffness and uncomfortable backing. Check the reverse as well as the face. A dense mark that looks impressive on a cap may be unsuitable for a lightweight jersey. Record the approved thread references and stitch file revision so the next run does not rely on a loosely named file or a remembered machine setting.
Sublimation and transfers solve different problems
Dye sublimation uses heat to transfer dye into a compatible substrate, commonly suitable polyester. It can support extensive graphics without the same surface layer as a conventional print. However, base fabric, colour management and heat processing still affect the outcome. For cut-and-sew garments, check artwork alignment across panels and remember that seams interrupt the visual field.
Heat-applied transfers cover several technologies, including cut film and direct-to-film transfers. They are not interchangeable materials. Confirm compatibility with the garment, the required application conditions and any restrictions on fine detail or stretch. Polyester dye migration can alter light-coloured decoration, sometimes after the initial application. Evaluate the actual combination over an agreed observation period rather than approving only the moment it leaves the press.
Turn a good sample into a repeatable standard
Create a short approval record with the garment reference, artwork revision, decoration dimensions, position, colour references and sample identifier. Record agreed care tests and the specific changes that would trigger another sample. A new fabric colour, a different transfer material or a substituted thread may affect the result even when the artwork remains unchanged.
Define how production will be inspected. Check representative sizes and placements, not just the most accessible item in a carton. Separate measurable defects from subjective preferences, and agree how discrepancies are reported before the batch is dispatched. Retain an approved reference for future reorders. A signed proof controls the information on a page; only a suitable physical reference demonstrates the finish you are asking production to repeat.
