Abstract: Micro characters are expressed by a thermal fusion transfer technique. In a printed matter manufacturing method, a printed matter is manufactured by heating a thermal transfer sheet in accordance with image data, the thermal transfer sheet including a base member, a release layer disposed on the base member and containing a wavelength conversion material that emits visible light with excitation by invisible light, and a thermally fusible ink layer disposed on the release layer, and by transferring the thermally fusible ink layer to a transfer-receiving body. In this method, the image data includes a first pattern and a second pattern. The second pattern is disposed on the first pattern and has a maximum width of a predetermined value or less.
