The invention provides an over-limit colorful code anti-counterfeiting method and printed matters. Codes formed by onsite color blocks in various kinds of colors (exceeding the maximum quantity of color groups of a printing machine) are arranged on a printed matter. Color characteristic information and position information of onsite color blocks are shot and acquired and then stored in a computeranti-counterfeiting network checking system database by combining the codes to serve as a personality characteristic information file. When a consumer verifies the authenticity, he/she shoots the onsite color blocks by use of a shooting mobile phone and uploads information to the computer anti-counterfeiting network checking system, and authenticity verification conclusions are made through software. According to the invention, a digital anti-counterfeiting technology loophole that 'a thief in the family is difficult to detect' is plugged.
