Why Do Colours Look Different on a Printed Shirt Than on Screen?

Printed shirt colours differ from your screen for the same reason all print does — screens emit RGB light, printing uses CMYK ink — plus two garment-specific factors: the fabric colour underneath and the fabric type both shift the result. On a coloured or dark shirt, ink interacts with the base; on textured fabric, colour reads differently than on smooth paper. Bright blues and neons drift most.

What shifts garment colour

Factor	Effect
RGB → CMYK	Vivid blues, greens, neons dull
Shirt base colour	Ink over colour ≠ ink over white (underbase helps)
Fabric type	Texture and absorbency alter appearance
Print method	Sublimation, DTF and screen render colour slightly differently

Getting brand colours right on garments

Supply the CMYK breakdown (or a Pantone reference), not just a hex code or a screenshot. For critical brand colours — a company uniform that must match the van and the website — ask for a printed proof on the actual garment before committing the run. Screen matching a Pantone is most precise; DTF and DTG work in CMYK.

The dark-shirt factor

On dark garments, colours only look true because of the white underbase printed first. Without accounting for it, that bright red goes muddy. It's why the same file can look different on a white tee and a navy one.

Realistic expectations

Print gets you very close, not pixel-identical to a glowing screen — that's physics, not a fault. A proof removes surprises for anything where colour is business-critical; for a fun event tee, close is fine.

FAQ

Can you match my exact brand colour? Very closely with CMYK/Pantone values and a proof — screen printing matches Pantones best. Why did my logo blue turn purple-ish? Classic RGB-blue-to-CMYK shift; supply CMYK values to control it. Do you offer printed proofs on garments? For critical colour matches, ask — worth it before a big run.
