The data of CMY ink’s gray balance are got to define the replacement relationship between CMY and K ink by experiment with the digital printer. A special image was got by using CMY and K ink according to the principle of Gray Component Replacement (GCR).The image will have two different appearances by using the spectral response properties of CMY and K ink under visible light and infrared light．This kind of image can achieve the purpose of anti-counterfeiting printing.
