When preparing graphics for print, one of the most common (and important) questions we hear is:
Should this be a vector file or a raster file? or What is a vector file?
While both file types are essential in graphic design, they serve very different purposes. Understanding the difference can save you time, money, and frustration—and ensure your final printed piece looks sharp and professional.
Let’s break it down.
What Is a Vector File?
Vector files are made up of mathematical paths, not pixels. Instead of storing image information as dots, vectors use points, lines, and curves that are calculated by the software.
Common vector file types include:
- AI (Adobe Illustrator)
- EPS
- PDF (when saved as vector)
- SVG
Why vectors are great for print:
- Scalable without losing quality – Enlarge or shrink infinitely
- Crisp, clean edges – Perfect for text and logos
- Smaller file sizes for simple artwork
- Easy to edit colors and shapes
Best uses for vector files:
- Logos
- Text-heavy designs
- Icons and illustrations
- Signage and large-format printing
- Business cards, brochures, and branding materials
If it needs to be resized or reused across multiple print projects, vector is king 👑.
What Is a Raster File?
Raster files (also called bitmap images) are made up of pixels—tiny squares of color arranged in a grid. Each pixel has a fixed position, which means raster images have a set resolution.
Common raster file types include:
- JPG / JPEG
- PNG
- TIFF
- PSD
- GIF
Why raster files are useful:
- Excellent for detailed images
- Capture subtle color variations
- Ideal for photography and complex artwork
Best uses for raster files:
- Photos
- Scanned artwork
- Detailed textures or gradients
- Web images (with proper resolution for print)
The key limitation? Scaling up raster files can cause pixelation and blurriness if the resolution isn’t high enough.
Resolution Matters (Especially for Print)
Raster images rely heavily on resolution, typically measured in DPI (dots per inch).
- 300 DPI → Ideal for high-quality printing
- 72 DPI → Common for web, but too low for print
Once a raster image is created at a low resolution, it can’t truly be fixed later. Increasing the DPI after the fact doesn’t add detail—it just spreads existing pixels over a larger area.
Vector files don’t have this problem because they aren’t resolution-dependent.
Vector vs. Raster: Quick Comparison
| Feature | Vector | Raster |
| Scales without quality loss | ✅ Yes | ❌ No |
| Best for logos & text | ✅ Yes | ❌ No |
| Best for photos | ❌ No | ✅ Yes |
| Resolution-dependent | ❌ No | ✅ Yes |
| Ideal for large-format print | ✅ Yes | ❌ Risky |
Which Should You Use for Printing?
The answer depends on what you’re printing:
- Logos, text, branding, signage → Vector
- Photos, detailed images → High-resolution raster
- Mixed designs → Often a combination of both
Most professional print files use vector layouts with embedded raster images at the correct resolution.
Not Sure What You Have? We Can Help.
One of the most common issues in printing is receiving files that look great on screen—but don’t hold up on press. Knowing whether your artwork is vector or raster (and if it’s print-ready) makes all the difference.
If you’re unsure about your files, resolution, or format, our team is happy to review your artwork before printing and help you get the best possible result.
