What Is a Vector File? Is it Important to Have Them?

What Is a Vector File?

A vector file uses mathematical equations to create shapes, lines, and colors. Instead of pixels, vector files rely on points and paths. This means that vector images can be scaled infinitely without losing any quality or clarity.

Common vector file types:

• .AI (Adobe Illustrator)
• .EPS
• .SVG
• .PDF (if saved as vector)

What Is a Raster File?

A raster file is made up of a fixed number of pixels. These are typically used for photos or complex images. The downside is that when you try to enlarge raster images, they often become blurry or pixelated because the number of pixels stays the same.

Common raster file types:

• .JPEG
• .PNG
• .GIF
• .BMP

 

Why Having Vector Files Is Important

 Scalability Without Loss of Quality: Whether you need your design for a business card or a billboard, a vector image will maintain its sharpness and clarity at any size.

Editability: Vector files allow designers to easily change colors, shapes, or layouts without starting from scratch.

Professional Printing: Most printers, especially those working with apparel, signs, or promotional items, require vector files for accurate and high-quality reproduction.

Smaller File Sizes: Vector files are often much smaller than high-resolution raster files, making them easier to store and share.

How to Ask for Vector Files from Your Artist

When you’re working with a designer for your custom apparel or logo, always specify that you need vector files. Here’s how you can ask:

• “Can you provide the final logo in vector format, such as .AI, .EPS, or .SVG?”
• “I need this design to be scalable, so a vector file is important.”

Most artists understand the need for vector files for logos, signs, and custom apparel, but it never hurts to be specific!
