To determine whether a file is a vector, you can check its file extension or enlarge the image on your screen.

Check the file extension:

• If the file has an extension like .ai, .eps, .svg, or .pdf, it’s probably a vector file. However, not all files with these extensions are guaranteed to be vectors, as some may contain raster images.

Enlarge the image:

• Zoom in to at least 200%. If the edges remain sharp and the colors stay solid, it’s likely a vector. If the edges become blurry or the colors break into different shades, it’s a raster file.

Vector files explained:
Vector files use mathematical formulas to create images with lines and points, which allows them to scale without losing clarity. Unlike raster formats (.jpg, .png), vectors retain sharpness at any size.

Common vector file types:

• .ai: Adobe Illustrator’s native format.
• .eps: Encapsulated PostScript, a longstanding vector format.
• .pdf: Portable Document Format, commonly used for sharing vector files.
• .svg: Scalable Vector Graphics, a modern, web-friendly format.

Understanding Vector vs Non-Vector Artwork

In summary, when it comes to printing, using the correct file format is essential for high-quality results. Vector artwork is created using mathematical equations that allow it to scale infinitely without losing clarity, making it ideal for logos, illustrations, and graphics that need to be resized frequently. Common vector file formats include .ai, .eps, .svg, and .pdf. These files ensure crisp, sharp edges regardless of how large or small the image needs to be.

In contrast, non-vector or raster files like .jpg, .png, and .gif are made of pixels, meaning they lose resolution when enlarged, often resulting in a blurry or pixelated image. For printing, this can lead to poor-quality prints with fuzzy edges.

To determine if your artwork is vectored, check if it maintains sharpness when zoomed in or if it's in one of the accepted vector formats. If your artwork isn't vectored, you may need to convert it before sending it for production to ensure the best possible outcome for your printed materials.
