Logo File Formats: What Your Artwork Needs to Print Right
Vector vs raster is the difference between a logo that scales clean and one that prints fuzzy. Here is what every format does, when each is fine, and how a bad file gets fixed.
A vector logo is drawn with math, so it scales to any size with perfectly clean edges; a raster logo is a grid of pixels, so it blurs and stair-steps when enlarged. That is the entire vector vs raster question, and it is why decorators ask for vector files like AI, EPS, SVG, or vector PDF before production starts.
The good news: you do not need to be a designer to send usable art. Learn what the formats mean, check what you have, and let an art team close whatever gap remains.
What Is the Real Difference Between Vector and Raster?
Vector files store shapes as curves and points, which a machine can redraw at business card size or banner size with identical crispness. Raster files store a fixed grid of pixels; enlarge them and software must invent pixels, which reads as blur. Decoration equipment such as screen burners, embroidery digitizers, and laser engravers all trace shapes, so they want curves, not pixels.
Which File Format Is Which?
Six extensions cover nearly every logo file a buyer will ever send.
| Format | Type | Best Use | Watch Out |
|---|---|---|---|
| AI | Vector | Master logo source file | Needs Illustrator to open |
| EPS | Vector | Sharing with any shop | Old previews look rough |
| SVG | Vector | Web and cutting machines | Confirm fonts are outlined |
| Either | Proofs and print handoff | Only vector if saved that way | |
| JPG | Raster | Photos, quick previews | Compression adds artifacts |
| PNG | Raster | Web logos, transparency | Fixed resolution limits size |
When Is a JPG or PNG Actually Fine?
Raster art is not the enemy; low resolution is. Photographic methods such as DTG, dye sublimation, and full color plates print raster images all day when the file is big enough: aim for 300 DPI at the final printed size. A 4000 pixel wide PNG can print a sharp 13 inch design, while the same logo saved at 400 pixels cannot.
What If You Only Have a Low-Res Logo?
Most buyers only have whatever file marketing left behind, and that is workable. Sparta’s art team redraws logos into clean vector artwork as part of the ordering process, then sends a free design proof so you approve the rebuilt art before production. Send the biggest file you have plus any brand colors, and the redraw handles the rest.
How Should You Hand Off Artwork?
- Send the source. AI, EPS, SVG, or a vector PDF beats a screenshot every time.
- Outline the fonts. Converting text to curves keeps typefaces intact on any computer.
- Name your colors. PMS numbers keep brand color exact across methods and reorders.
- Skip the resize. Send art at full quality and let the shop scale it to the placement.
Frequently Asked Questions
Check the extension first: AI, EPS, and SVG are vector formats. For a PDF, zoom far in; vector art stays crisp at any magnification while raster art pixelates.
Auto-trace tools handle simple, clean marks, but professional results usually come from a manual redraw. Complex logos are rebuilt curve by curve to stay faithful to the original.
About 300 DPI at the final printed size is the standard. A logo printing 10 inches wide should be roughly 3000 pixels wide.
Screens mix light as RGB while printing mixes ink as CMYK or PMS, so some vivid screen colors shift on fabric or metal. Naming PMS colors keeps the output predictable.
Policies vary by shop. At Sparta the art rebuild and the design proof are part of the quote, so you see final artwork before committing to anything.
Not Sure What File You Have?
Attach whatever artwork exists to a quote request, and the art team will confirm it, rebuild it if needed, and proof it free.
