"Vector", "pixels", "300 dpi"… these words come up as soon as files are mentioned — and no one really explains them. Here, jargon-free, is what a vector file is and why it's the key to a sharp jersey, whatever its size.
A pixel image is a grid of small coloured squares. Enlarge it and the squares become visible: the "staircase" effect. A vector file, by contrast, is described by mathematical shapes — it stays perfectly sharp, whether it's 3 cm or 1 metre.
On a kit, the same crest can be tiny on the chest and printed large on the back. With a vector file, you can enlarge or shrink it endlessly without ever losing sharpness. A pixel image, by contrast, degrades as soon as you stretch it — blurry outlines, staircased edges.
That is exactly what sublimation requires: clean flat areas and sharp outlines, embedded in the fibre of the fabric.
The same vector path, resized — always sharp.
AI, EPS or vector PDF. Sharp at any size, usable directly, from a small crest to a full-surface design.
A PNG at 300 dpi minimum can work in some cases. Below that, the artwork will need to be redrawn.
Blurry logo, low resolution or an AI visual? Our studio le vectorise — reconstruit en fichier net et exploitable.
Colours: send them as Pantone ou CMYK, never in RGB (made for screens, it varies from one display to another). See colours & Pantone →
Not sure your file is vector? Drop it here: we'll give you an instant first verdict. It's a guide; our studio always confirms on receipt.
Midjourney, DALL·E, ChatGPT, Stable Diffusion… these images are an excellent source of inspiration, but they are not vector files: their colours are not calibrated and their details do not hold up to textile printing. Our studio fully recreates them as vector artwork before manufacturing.
You don't need to be a graphic designer to get a great-looking kit.
Send it to us: we'll tell you whether it's usable, and if not, we recreate it as vector artwork. Made in Europe, from a single piece.
