The Application Research on Anti-counterfeiting of Fractal Graphics in Color Printing Based on Newton Iteration and Escape Time Algorithm

The anti-counterfeiting printing which is a branch of feature printing is an anti-counterfeiting technology. Anti-counterfeiting printing technology is a measure which is used to prevent somebody unwarranted from copying, counterfeiting and imitating. Fractal graphics is applied to color printing anti-counterfeiting in this paper because of its protean shape and unpredictable color. The detailed analysis of Julia set escape time algorithm of Newton iterative method shows that the method of color printing anti-counterfeiting combined with fractal graphics has prefect anti-counterfeiting functions. No one can get the same graphics with original picture by common methods of duplicating, scanning, photographing and other measures.
