Got a logo that looks great on your website? Does it look crisp and sharp on your business card? It’s a start, but what many people don’t realize is that a small image, when scaled up hundreds of times, can become pixelated, blurry, and difficult to read.
To make that professional first impression, providing the correct artwork files for your sign design is the most important step.
If your sign company is asking for specific file formats, there is a very good reason for it. Providing the right files (often vector files) ensures your finished sign looks crisp, professional, and represents your brand well. In this guide, we will explain what files you need and why they are so important.
Does the Artwork File Quality Actually Matter?
Yes. If the image wasn’t created to scale, then it might look terrible when stretched to sign size. Logos designed solely for the web are often not appropriate for large-scale signage because the output size is just too drastically different.
But it’s not just the blurry fabrication that you need to worry about. Low-resolution images can lead to unexpected production delays and added costs to fix the artwork. At Landmark Sign, we want your finished sign to look fantastic. To achieve a flawless sign design that you’ll love for years to come, the process has to start with the highest quality vector files.
The Magic of Vector Files
We’ve mentioned vector files a few times now, but what exactly are they? A vector file is an image built by mathematical formulas that establish points on a grid, rather than colored blocks. Think of it like this: a regular image file (like a JPG) is like a mosaic made of tiny, fixed-size tiles. If you try to make the mosaic bigger, you’re just stretching the tiles, which makes the image blurry.
A vector file, on the other hand, is like a set of instructions for drawing a picture. It says, “Start here, draw a line to there, make a curve like this.” Because it’s a set of instructions, you can make the drawing as big or as small as you want, and it will always be perfectly sharp—no quality lost. Whether your sign is the size of a laptop or a billboard, vector files will never begin to pixelate.
This is why vector files work like magic for custom sign designs.
Vector File Formats
Look for these file extensions:
- .EPS (Encapsulated PostScript)
- .AI (Adobe Illustrator)
- .SVG (Scalable Vector Graphics)
- .PDF (Portable Document Format)
Don’t worry if you can’t open the file on your computer. Graphic designers and our design team use specific software to view and use the files. You just need to track them down and pass them along to our sign design team.
What If I Only Have a JPG or PNG?
Raster files, such as JPGs, PNGs, and screenshots, are made of pixels. Pixels are squares of color similar to the mosaic tiles we talked about earlier. They have a fixed resolution, which means their quality breaks down rapidly when they are scaled up. If you try to stretch a small raster image into a large sign, it quickly starts to look like it was made on MS Paint in 1985.
When might a raster file work? High-resolution raster files might occasionally work for some printed applications, like small window graphics. However, it’s best to consult with your sign design expert first to ensure the resolution is high enough for a quality print.
When won’t they work? Low-resolution logos pulled directly from a website—think Canva or Kittl, which typically export images in 72 DPI—simply aren’t large enough for signage. Likewise, screenshots or logos embedded in Word documents or PowerPoints are unusable for commercial sign design. If you cannot provide vector files, your raster images must be extremely high resolution.
Frequently Asked Questions
Why can’t I just send my logo as a JPG or PNG?
JPG and PNG files are pixel-based and become blurry at scale. Sign companies require vector files to ensure your logo retains sharp lines, no matter how large your sign.
What if I don’t have a vector version of my logo?
Your first step should be to contact the original graphic designer who created your logo. They typically keep vector files on hand and can easily email them to you. If that isn’t possible, your sign company may need to recreate your logo for an additional fee.
Does a PDF work for sign artwork?
This comes down to how the PDF was originally created. If the PDF was saved directly from a vector-based design program, it will work perfectly. Unfortunately, you can’t cheat the system by simply saving a low-resolution JPG as a PDF document. It won’t be usable.
Do I need to provide color codes for my sign?
Yes, whenever possible! Providing specific color codes, like Pantone, CMYK, or HEX values, helps your fabricators perfectly match your brand colors.
Create a Sign That’s a Work of Art
Having the right vector file means getting the exact sign design that you imagined. Remember, an outdoor sign is the first impression your business makes, so you want it to look perfect!
