具有三维移动隐藏图像效果的磁性安全元件及其印刷方法
Abstract:
本发明涉及一种具有隐藏图像的磁性安全元件及其印刷方法，所述方法包括步骤：使用磁性油墨在基底的表面上印刷特定细线图案，使用磁体将磁场施加到基底上，以及对基底进行干燥和固化。依照本发明，能够形成隐藏图像，其无法通过复制实现并可以可逆地出现和消失。因此，根据本发明的磁性安全元件及其印刷方法可以用于防止伪造或变造。
Abstract(English):

The present invention relates to a magnetic security element having a hidden image and to a method for printing the element. The method comprises the steps of printing a specific thin line pattern on the surface of a base using magnetic ink, applying a magnetic field using a magnet to the base, and drying and hardening the base. According to the present invention, the hidden image which cannot be realized by copying and which exhibits reversible effects of appearance and disappearance may be formed. Therefore, the magnetic security element and the method for printing the element according to the present invention may be used in anti-forgery and anti-falsification.
