DPI
DPI (Dots Per Inch) is a measurement that shows how detailed or sharp a printed image will be. Think of it like the clarity of a TV screen - the higher the number, the clearer the picture. In print-on-demand jobs, DPI is crucial because it determines the quality of printed products like t-shirts, posters, or books. When you see "300 DPI" or "high DPI" in job descriptions, it means the role involves working with high-quality print files. This term is often paired with "resolution" or "print quality" and is essential knowledge for designers and print production staff.
