Abstract

A secret marker for the antiforge information medium is one or more areas printed with a disclosed ink A alone or in conjunction with ordinary ink B having similar color. Said marker has the metamerism characteristics in the 550-820 mm range. Under the irradiation of ordinary light source, part of said marker can show another color if it is observed via a (55-820)-mm optical filter, so displayingthe hidden information.

Description

technical field [0001] The invention relates to a security mark on an anti-counterfeiting information carrier, a testing method and a testing device, and belongs to the technical field of anti-counterfeiting printing. Background technique [0002] The security mark is the product of the effective combination of anti-counterfeiting ink and printing technology. In modern society, the application of confidentiality marks has played a very good role in combating counterfeiting and shoddy products. The anti-counterfeiting effect of the security mark is directly related to the properties of the anti-counterfeiting ink. At present, the most widely used anti-counterfeiting inks mainly include eight categories: (1) ultraviolet laser fluorescent inks; (2) infrared anti-counterfeiting inks; (3) heat-sensitive anti-counterfeiting inks (thermochromic anti-counterfeiting inks or temperature-changing anti-counterfeiting inks); (4) Moisture-sensitive color-changing anti-counterfeiting ink...
