摘要
PROBLEM TO BE SOLVED: To provide a method capable of identifying the genuineness, which is applied to a precious printed matter requiring prevention of counterfeiting, and in which a latent image appears by observing the printed matter from an oblique angle. SOLUTION: The printed matter is obtained by first providing a basic image (2) on a top surface of a light transmitting base material (1). The basic image (2) is composed of line drawings and/or dot patterns. The basic image (2) is divided into a background image part and a message image part applying at least one latent image. The background image part and the message image part have a certain form of a visually unidentifiable slit-pattern structure having a different angle of the direction of arrangement, in each drawing lines and/or in each dots of line drawings and/or dot patterns, respectively. The light reflecting basic material (4) is provided at the backside of the region of the light transmitting basic material (1) where the basic image (2) is printed.
