A measurement of spatial print density defining the level of resolution and clarity in a digital graphic file.
DPI (Dots Per Inch) is a vital metric that defines the resolution, density, and print clarity of a digital raster graphic image file (such as a PNG or JPEG). When digital designs are converted into physical apparel prints, the DPI represents how many individual dots of ink the printhead will spray within one linear inch of the garment. If a graphic downloaded from the internet has a standard low-resolution display setting of 72 DPI, and is stretched to fit an A3-sized print area on a heavyweight streetwear t-shirt, the printer will stretch the tiny pixel grid, resulting in a highly pixelated, blurry, and unprofessional print. High-quality DTF and DTG garment printing require all uploaded files to be exported at exactly 300 DPI at the physical size the graphic is intended to be printed (e.g., 300 DPI at 12 x 16 inches). This ensures that every edge is razor-sharp, text is perfectly legible, and gradients blend smoothly.
