Document Type and Number:
WIPO Patent Application WO/2022/030430
Kind Code:
A1
Abstract:
In the present invention, microcharacters are expressed with a thermal fusion transfer scheme. In this printed matter manufacturing method, printed matter is manufactured by heating, on the basis of image data, a thermal transfer sheet, and by transferring a thermally fusible layer ink layer onto a transfer body. The thermal transfer sheet comprises: a base material; a release layer which is provided on the base material and contains a wavelength conversion material that emits visible light by invisible light excitation; and the thermally fusible ink layer provided on the release layer,. In this method, the image data includes a first pattern, and a second pattern which is disposed on the first pattern and has a maximum width that is no more than a predetermined value. When transferring the thermally fusible ink layer to the transfer body, a region corresponding to the first pattern excluding the second pattern is heated, a region corresponding to the second pattern is not heated, and the thermally fusible ink layer in a region corresponding to the first pattern including the second pattern is transferred to the transfer body.
