Vector vs. Raster Graphics: Facts, Myths and Legend
Posted by Scott Beardsley on 20th Oct 2025
When it comes to creating printed materials—whether it's custom signage, promotional items, or branded merchandise—understanding the difference between vector and raster graphics can save you time, money, and a lot of frustration. Let's break down what you need to know.
What Are Raster Graphics?
Raster graphics, also called bitmap images, are made up of tiny colored squares called pixels. Think of them like a mosaic—when you zoom in close enough, you can see all the individual tiles that make up the picture. Common raster file formats include JPEG, PNG, GIF, and TIFF.
Imagine this: Take a photo with your phone of your logo painted on a wall. That photo is a raster image. It looks great at the size you took it, but if you try to blow it up to billboard size, it becomes pixelated and blurry because you're essentially making those tiny squares bigger.
Best Use Cases for Raster Graphics:
- Photography - Product photos, team headshots, event images
- Web graphics where file size matters and dimensions are fixed
- Social media images that won't be resized beyond their original dimensions
- Digital presentations and screen-only content
What Are Vector Graphics?
Vector graphics are built using mathematical formulas that define points, lines, curves, and shapes. Instead of being limited to a fixed number of pixels, vectors can scale infinitely without any loss of quality. Common vector formats include AI (Adobe Illustrator), EPS, SVG, and PDF (when created properly).
Imagine this: Your logo as a vector file is like a recipe rather than a photograph. The file contains instructions that say "draw a blue circle here, a red line there, and this specific curve connecting them." No matter what size you need, from a business card to a 10-foot banner, the computer follows those instructions perfectly.
Best Use Cases for Vector Graphics:
- Logos and brand marks that need to appear on everything from pens to building wraps
- Typography and text especially for signage and large-format printing
- Icons and illustrations with clean lines and solid colors
- Vehicle wraps and building graphics
- Custom printed promotional items like tent covers, table throws, and gift boxes
The Canva Myths
Canva has revolutionized design accessibility, and we appreciate that! It's made creating attractive graphics possible for everyone. However, when it comes to professional printing, Canva has some significant limitations:
The Export Problem
Canva primarily exports to raster formats (PNG, JPG) or a flattened PDF. While Canva does offer PDF and SVG downloads, these files often:
- Flatten text into images rather than keeping them as editable vectors
- Embed low-resolution images that look fine on screen but fail in print
- Convert vector elements into raster graphics during export
- Create files that can't be easily edited by professional print software
Resolution Restrictions
Even at Canva's highest quality settings, exported files may not meet professional print standards for large-format applications. That design that looks perfect on your screen at 72 DPI will show obvious quality issues when printed at the required 300 DPI.
Color Mode Mismatch
Canva works in RGB (screen colors), while professional printing uses CMYK (print colors). This means the vibrant blue you see on your monitor might print as a different shade entirely. Professional design software allows precise CMYK color management.
Limited Bleed and Trim Setup
Professional printing requires bleed areas (extra image extending beyond the cut line) and crop marks. Canva doesn't provide the precise controls needed for these technical print requirements.
Font Embedding Issues
Custom fonts in Canva often get converted to images or outlines that can't be adjusted, making last-minute text changes impossible and sometimes creating unexpected print quality issues.
Why Vector is Legendary
When you're working with a print agency like VOX, we almost always request vector files for one critical reason: scalability without quality loss. Here's why this matters:
1. Infinite Scalability
Your logo might need to appear on a business card (2 inches wide) and on a 10x10 tent cover (120 inches wide). A vector file handles both perfectly. A raster file? The business card might look okay, but that tent will showcase every pixelated edge.
2. Crisp, Clean Lines
Vector graphics produce razor-sharp edges and text, even under magnification. This is essential for maintaining your brand's professional appearance across all printed materials.
3. File Size Efficiency
A vector logo file might be just a few kilobytes, while a raster version at print resolution could be several megabytes. This makes vectors easier to store, share, and process.
4. Easy Color Adjustments
Need your logo in a different color for a special promotion? Vector files make color changes simple and precise, which is crucial when matching specific Pantone colors for brand consistency.
5. Print Resolution Independence
Raster images need to be at least 300 DPI (dots per inch) for quality printing. Miss that mark, and your print will look fuzzy. Vectors don't have this limitation—they're always print-ready at any size.
The Bottom Line
Choose RASTER when:
- You're working with photographs
- Content is digital-only
- You need realistic textures and complex shading
Choose VECTOR when:
- Creating logos or brand elements
- Designing anything that might be resized
- Preparing files for professional printing
- You need text to remain sharp and editable
