A visual guide for Pronto Reprographics customers.
If you’ve ever sent your logo to a print shop and been told it’s “too low resolution” or “not print ready,” there’s a good chance the problem was the file type — not the logo itself. The solution in almost every case is a vector file. Once you understand what a vector file is and why it behaves differently from a regular photo or image, you’ll never have a blurry logo problem again.
First, Let’s Talk About Regular Images (Raster Files)
Most images people work with every day are called raster files — JPEGs, PNGs, and GIFs are all raster files. A raster image is made up of a fixed grid of tiny colored squares called pixels. Think of it like a bathroom tile floor — it looks smooth from across the room, but get close enough and you can see the individual tiles.
The problem with raster files is that they have a fixed number of pixels. When you try to make them bigger, the software has to guess what goes between the existing pixels and fill in the gaps — which results in that familiar blurry, blocky look. Once a raster image is created at a certain size, you simply cannot make it significantly larger without losing quality.
So What Makes a Vector File Different?
A vector file doesn’t use pixels at all. Instead of storing a grid of colored squares, a vector file stores mathematical instructions — essentially a set of equations that describe shapes, lines, curves, and colors.
For example, instead of storing thousands of pixels that make up a circle, a vector file just stores the instruction: “draw a circle at this location, with this radius, filled with this color.” When you need to print it larger, the software just recalculates the math at the new size — and the result is always perfectly sharp. Always.
This is why a vector logo can be printed on a business card and then blown up to cover the side of a building — and look identical at both sizes. The math scales. Pixels don’t.
A Simple Way to Picture It
Here’s an analogy that makes vector vs raster click for most people:
| A raster file is like a photograph printed on paper. Enlarge it and it gets blurry. You can’t change it without reprinting. A vector file is like a stencil with instructions. Make it any size you want — it always comes out perfectly clean. |
Vector vs Raster — Quick Comparison
| Vector | Raster (JPEG/PNG) | |
| Scale to any size | ✅ Yes — always sharp | ❌ No — gets blurry |
| Editable text & colors | ✅ Yes | ❌ No |
| Small file size | ✅ Usually | ⚠️ Depends |
| Best for logos | ✅ Yes | ❌ No |
| Best for photos | ❌ No | ✅ Yes |
| Print ready at any size | ✅ Yes | ⚠️ Only at correct DPI |
What Do Vector Files Look Like? Common File Extensions
You can usually tell if a file is a vector by its file extension — the letters after the dot in the filename.
Here are the most common vector formats:
| Extension | Full Name | Created In | Notes |
| .AI | Adobe Illustrator | Adobe Illustrator | The gold standard for logos and artwork |
| .EPS | Encapsulated PostScript | Illustrator, CorelDRAW | Universal vector format, widely accepted |
| .SVG | Scalable Vector Graphic | Illustrator, Inkscape, Web | Great for web and modern print workflows |
| Portable Document Format | Almost any program | Vector-based PDFs print beautifully | |
| .CDR | CorelDRAW | CorelDRAW | Common in sign shops; export as EPS/PDF |
Important note about PDFs: Not all PDFs are vector files.
- A PDF can contain either vector artwork or raster images — it depends on how it was created.
- A PDF exported from Adobe Illustrator will be vector.
- A PDF made from a scanned document or a photo will still be raster.
When in doubt, send us the original source file along with the PDF.
Why Print Shops Ask for Vector Files
Now that you know what a vector file is, here’s why we specifically ask for them at Pronto Reprographics:
1. We print at many different sizes
Your logo might appear on a business card today, a poster next month, and a banner next year. A vector file handles all of those without any quality loss. A JPEG does not.
2. We can edit colors if needed
Vector files keep your design elements separate and editable. If your logo needs to print in all-black for a one-color job, or if we need to adjust a color for a specific ink or substrate, we can do that cleanly with a vector file. With a JPEG, colors are baked in and can’t be separated.
3. Lines and text stay razor sharp
This is especially critical for blueprints, technical drawings, and anything with fine lines or small text. Vector lines never get soft or blurry regardless of the output size or resolution of the printer.
4. It saves you money and time
When we receive a low-resolution raster file, we have to contact you, wait for a replacement file, and delay your job. Sending a vector file upfront means your job goes straight to print with no back-and-forth.
How Do I Get a Vector Version of My Logo?
This is the most common question we get after explaining vectors. Here’s what to do depending on your situation:
If a designer created your logo
Ask them for the original source file in .AI or .EPS format. Any professional designer should have this. It’s your logo — you have every right to request the original files you paid for.
If your logo came with your business registration or franchise
Contact your corporate office or franchise support team and ask for a vector version of the logo. Most established brands maintain a brand asset library with vector files available.
If you only have a JPEG or PNG
You have two options. First, a graphic designer can manually re-trace your logo and recreate it as a vector — this is called vectorization or logo redraw, but it can be expensive. Second, there are automated tools like Adobe Illustrator’s Image Trace feature that can sometimes convert simple logos automatically, though results vary. We can point you in the right direction if you’re not sure.
If you’re creating a new logo
Make sure your designer delivers the final logo as an .AI or .EPS file from day one. This should be standard practice — if a designer won’t provide vector source files, that’s a red flag.
What If I Design Things Myself in Canva?
Canva is a popular tool and it’s great for many things — but it has an important limitation when it comes to vector files. Standard Canva accounts only export PNG and JPEG files, which are raster formats.
Canva Pro subscribers can export SVG files for simple designs, which is a vector format. However, Canva’s SVG exports can sometimes have limitations with complex designs or embedded fonts.
Our recommendation for Canva users:
- For documents, flyers, and posters: export as PDF Print at the correct final size. This gives you the best quality Canva can offer.
- For logos: Canva is not the ideal tool for creating logos that need to scale to large print sizes. Consider having a graphic designer create your logo in Illustrator if wide-format or large-format printing is in your future.
- When in doubt: send us what you have and we’ll tell you honestly whether it will work for your specific job.
Quick Cheat Sheet — Vector File Do’s and Don’ts
| ✅ DO send .AI, .EPS, .SVG, or vector PDF files for logos and artwork ✅ DO ask your graphic designer for original source files ✅ DO design at the actual final print size when using raster tools ✅ DO send photos as high-res JPEGs or TIFFs (photos don’t need to be vector) ❌ DON’T send logos as JPEG or PNG files if you have a vector version ❌ DON’T screenshot a logo from a website and send that as your file ❌ DON’T assume a PDF is always vector — check how it was made ❌ DON’T resize a JPEG to be larger and assume it will print well |
Not Sure What File Type You Have? We’ll Check It for You.
Just send us your file and describe what you’re trying to print. We’ll take a look and let you know right away whether it’s print-ready, needs adjustments, or needs to be recreated as a vector. We’d rather spend two minutes reviewing your file than have you unhappy with the result.
