A rubber stamp creates a c) relief print.
Explanation: In the context of printing techniques, a relief print is made by transferring ink from the raised surface of a printing plate to paper. Rubber stamps are designed with raised images or text that, when pressed onto an inked surface and then onto paper, leave an impression. This method distinguishes it from other printing techniques such as lithography or silkscreen, where different processes are used to create the final printed image.
