Abstract
Abstract An indentification card wherein any required characters, designs and/or embossings are made on the base material of the card and an engraved image by which the user can be identified and which has no projections thereon is made in the part of a colored layer provided on the base material of the card. A method of making an identification card which comprises making any required characters, designs and/or embossings on the base material of the card, further providing a colored layer on the base material of the card and then engraving the part of said colored layer to be in the form of fine lines and points so that, by regulating the ratio of the surface areas of the engraved part and unengraved part, the differences in the color thickness and luster may be expressed to form any engraved image by which the user can be identified and which has no projections thereon.
