    • With the aim of realizing an easy and inexpensive method of realizing a "stealth" dot pattern, whose presence on a medium surface is not visually recognizable, merely through minor improvements in the existing printing technology, the present invention provides dots which form a dot pattern by printing these dots using an ink of any color reactive in the infrared or ultraviolet wavelength range on a medium surface on which a dot pattern is to be formed, for use with a dot pattern reading system that irradiates infrared or ultraviolet light on a medium surface having a dot pattern provided thereon, recognizes the dot pattern by reading the reflections of the light with an optical reading means, converts the dot pattern into the corresponding data, and outputs the text, voice, images and so forth contained in the data.
    • 为了实现一种实现“隐形”点阵图案的简单和便宜的方法,其在中等表面上的存在不能在视觉上被识别,仅通过现有打印技术的微小改进,本发明提供了形成点图案的点 通过使用在要形成点图案的介质表面上的在红外或紫外线波长范围内具有反应性的任何颜色的墨水打印这些点,以便与在介质表面上照射红外或紫外光的点阵图形读取系统一起使用 具有设置在其上的点图案,通过用光学读取装置读取光的反射来识别点图案,将点图案转换成对应的数据,并输出数据中包含的文本,语音,图像等。
