Vector Vs Png For T Shirt Printing – tshirtprintlondon.co.uk

The file format you submit can make or break your print quality — here's the real difference between vector and PNG files, and which one you should be sending us.

1. What a Vector File Actually Is

Vector files (AI, EPS, SVG) store your design as mathematical shapes and paths rather than pixels, meaning they can scale to any size — from a small chest logo to a huge back print — without losing any sharpness.

2. What a PNG File Actually Is

A PNG is a raster image made of a fixed grid of pixels. It looks sharp at its original size but becomes blurry or pixelated when scaled up significantly beyond that size.

3. Why Scalability Matters

A logo that looks crisp as a small website icon can look rough and pixelated once printed at 12 inches wide — this is the single most common quality issue we see with PNG submissions.

4. When a PNG Is Actually Fine

A high-resolution PNG (300 DPI+ at the actual intended print size) prints perfectly well for most jobs — vector isn't mandatory, just ideal, especially for photo-realistic designs that can't be vectorized anyway.

💡 Pro Tip

If you only have a small logo pulled from a website, don't assume it's unusable — send it to us and we can often trace it into a clean vector file.

Format	Scales Without Quality Loss	Best For
Vector (AI/EPS/SVG)	Yes	Logos, text, embroidery
PNG (300 DPI+)	No	Photo-realistic, full-color art

Key Takeaways

Vector files scale to any size without losing quality.
PNG files are fixed-resolution and can blur when scaled up too far.
A high-resolution PNG works fine for most standard print jobs.
Vector is especially important for embroidery digitizing.
Low-resolution website logos are the most common quality issue we see.

Yes, our design team offers vector tracing services.

No, a high-resolution PNG works fine for most jobs.

It was likely a low-resolution PNG scaled beyond its original size.

At least 300 DPI at the actual intended print size.

Not typically — high-resolution PNG is the right format for these.

Yes, vector files are strongly preferred for embroidery digitizing.

Send it anyway — we'll assess if it's usable or needs recreation.

Not directly, though poor files may need cleanup work first.

Yes, we can provide both formats after cleanup or recreation.

Vector files are usually AI, EPS, or SVG; PNG and JPG are raster images.
