Vector or Raster? Why Your Logo File Format Decides Your Print
By The Velocity Wear Team
A brand asks for its logo on a hoodie, sends a PNG pulled from its own website, and is told it cannot be used. This feels obstructive and it is not — the file genuinely does not contain the information the process needs, and no amount of software will invent it.
The actual difference
A raster image is a grid of pixels. It has a fixed amount of information and enlarging it spreads that information over more space, which is why an enlarged logo looks soft and why the edges go stepped.
A vector file is a set of mathematical descriptions — this curve, this fill, this shape. It has no resolution, because it is instructions rather than pixels. Rendered at 2cm or 2 metres it is equally crisp, which is exactly what you need for a design going onto a chest print, a cap and a hang tag.
Why processes care
- Screen printing separates a design into one screen per colour, and separation works from defined shapes with hard edges. Vector gives that directly.
- Embroidery has to be digitised into stitch paths, and a digitiser working from clean vector outlines produces a far better result than one interpreting a blurry raster edge.
- Cut vinyl needs an actual cut path, which is a vector by definition.
- DTF is the tolerant one — it is a printing process, so it can work from raster provided the resolution is genuinely sufficient at final size.
Which files are which
Vector: AI, EPS, and PDF when it was actually created as vector. SVG. Raster: JPEG, PNG, GIF, and most TIFFs.
The trap is PDF, which can contain either. A PDF exported from a vector program is vector; a PDF containing a photograph of a logo is a raster image in a PDF wrapper. If you are unsure, zoom in a very long way — vector stays sharp indefinitely, raster goes to blocks.
If all you have is a JPEG
This is extremely common, particularly where a logo was made years ago by somebody no longer contactable. There are three routes.
Ask whoever made it for the source file, which is worth doing first because it takes an email and often works. Have it redrawn as vector, which is a straightforward job for a designer and gives you an asset you will use for the life of the brand. Or, if the raster is genuinely high resolution at final print size, print it with a process that tolerates raster — DTF will take it.
What does not work is running it through an automatic tracing tool and hoping. Auto-trace produces wobbly curves and stray points that look acceptable on screen and reveal themselves at 30cm across on a garment.
Outline your text
One specific thing that causes real problems: if your artwork contains live text and the recipient does not have that font, it will be substituted silently and your logo will arrive in a different typeface. Convert text to outlines before sending — it turns letters into shapes and removes the dependency entirely.
Keep an editable copy for yourself, obviously, because outlined text cannot be edited back into text.
Build the asset once
A brand that invests once in a proper vector logo — full colour, one colour, reversed for dark grounds, and a simplified version for small sizes — never has this conversation again. Every print, every embroidery, every label and every tag comes out of that one set of files.
It is a few hours of a designer's time and it pays back on the first production run.
