ABSTRACT:
A method for producing a relief, which comprises forming a layer of a pattern on the surface of a sheet made of a material having the property of increasing in volume when heated, said pattern being made of a material having a stronger ability to absorb light than the aforesaid material, and then irradiating strong light uniformly on the entire surface of the sheet to selectively heat that portion of the sheet which is adjacent the undersurface of the pattern layer, whereby the pattern layer is raised from the sheet surface corresponding to the increase of the volume of the sheet portion.
