Vector vs pixel artwork
Pixel (raster) images
Made of tiny coloured squares. Photos, screenshots, JPGs and most PNGs are pixel images. Enlarge them too far and they become blurry or blocky.
Vector artwork
Made of mathematical lines and shapes rather than pixels. A vector logo can be scaled from a business card to a billboard and stay perfectly sharp. Vector files describe exact outlines, which machines can follow.
Why signage needs vectors
- Cut vinyl lettering – the plotter cuts along the lines in the file.
- 3D letters and routed shapes – cutting machines follow the outlines. See 3D signage.
- Large prints – vectors stay sharp at any size.
- Colour accuracy – vector files make it easy to set exact brand colours.
For photographic prints, a high-resolution pixel image is fine. It is logos, lettering and shapes that need vectors.
Which files are usually vector
- AI (Adobe Illustrator)
- EPS
- SVG
- PDF – if it was exported from design software with vector content (a PDF can also just contain a pixel image)
- CDR (CorelDRAW)
Files that are usually not vector: JPG, PNG, GIF, BMP, a logo pasted into Word or PowerPoint, and images from websites or social media.
How to check your logo
- Open the file and zoom in a long way. If the edges stay crisp, it may be vector; if they go blurry or blocky, it is pixels.
- Ask whoever designed your logo for the original vector file. Designers and printers who worked on your branding often have it.
- Check old print jobs: whoever printed your business cards or signage may have a vector version.
If you only have a JPG
Do not worry. A pixel logo can be redrawn as a vector by a designer. It is a one-off job that pays off every time you order signage, vehicle graphics or print. Ask us about this through our sign design service. Once you have a vector logo, keep it safe and share it with every supplier.
