Pixels or Paths? Mastering Merch Design with the Right File Type

December 19, 2023

Understanding the difference between raster and vector files is crucial for creating high-quality designs.

This knowledge can be the key to unlocking the full potential of your merchandise, ensuring that your designs look as sharp on a t-shirt or a tote bag as they do on your computer screen. Let's dive into the world of raster and vector files and see how they can make or break your merch designs.

Raster 1
High resolution raster images are perfect for photos and detailed illustrations.

Raster files are images built from pixels – tiny coloured squares that, when combined in large quantities, form detailed images like photographs. The more pixels an image has, the higher its quality. Common raster file types include JPEG, GIF, and PNG. These files are great for displaying a wide array of colours and allow for extensive colour editing. They're perfect for detailed images, photos, and graphics. However, there's a catch – raster files lose quality when resized. If you zoom in or expand a raster image, it becomes blurred or pixelated. This is crucial to consider when designing merchandise, as a design that looks great on a small scale might lose its clarity when printed on a larger item.

Here are the common raster file types:

  • TIFF (Tagged Image File Format)
  • PSD (Adobe Photoshop Document)
  • PDF (Portable Document Format)
  • JPG (Joint Photographic Expert Group)
  • PNG (Portable Network Graphic)
  • GIF (Graphics Interchange Format)
  • BMP (Bitmap Image File)
Vector 1
Vectors allow for scaling without compromising the quality of the design.

Vector files, on the other hand, use mathematical equations to create images. They consist of lines, curves, and fixed points on a grid, with no pixels involved. This means that you can resize vector images infinitely without losing any quality. Vector files are ideal for logos, digital illustrations, and complex graphics that need to appear in various sizes. Their resolution remains consistent regardless of size, making them a go-to choice for designs that need to be versatile.

These common vector file types can be saved or edited in these formats:

  • AI (Adobe Illustrator document)
  • EPS (Encapsulated PostScript)
  • SVG (Scalable Vector Graphic)
  • PDF (Portable Document Format—only when saved from vector programs)
Choosing the Right File Type for Your Merch

When deciding which file type to use for your merchandise, consider the end use of your design. If you're working with detailed images or photographs, raster files might be your best bet. But if you need a logo or a graphic that needs to scale across different merchandise sizes, vector files are the way to go. Sometimes, you might even need to combine both raster and vector images in a single design, like using a vector logo with raster images in a brochure.

File Sizes and Compatibility

Raster files tend to be larger due to their high levels of detail and can impact storage space and web loading speeds. However, they can be compressed for easier sharing. Vector files are more lightweight, containing only the necessary mathematical formulas. While raster files are widely accessible and easy to edit, vector files might require specialised software. Our design tool accepts some of the more common formats, so make sure you've checked the upload formats before outputting your final artwork or requesting it from your designer.
