Vector graphics are the backbone of high-quality T-shirt and merchandise printing. Unlike raster images, vectors maintain sharpness at any size, making them ideal for logos, artwork, and custom designs. Whether you’re a designer or a business owner, knowing how to edit vectors properly ensures your prints look professional and vibrant. In this guide, we’ll explore essential vector editing techniques, tools, and best practices to optimize your designs for printing on apparel and merchandise.
