Realistic photograph of sublimation printing: a white polyester athletic jersey lying flat on the lower platen of an open heat press, just pressed, showing a vivid all-over gradient pattern in electric blue, purple and orange that fades smoothly across the whole fabric. A sheet of used sublimation transfer paper with a faded mirror image lies beside it. Clean, bright print shop setting, soft daylight. No text, no numbers, no letters, no logos anywhere.
