Comparing Photoshop and GIMP: Resizing Images for Fabric Printing and Understanding Pixels and DPI

When it comes to image editing software, Adobe Photoshop and GIMP (GNU Image Manipulation Program) are two of the most commonly used tools. Both have their strengths, especially when it comes to preparing images for printing, such as fabric printing. In this post, we’ll explore how to resize images in both Photoshop and GIMP for fabric printing, while also understanding the critical roles pixels and DPI play in the process.
