Owing to the special optical properties of surface gratings of laser rainbow holographic printed matter, the imaging by white light illumination can generate rainbow-colored interference fringes, which increase the difficulty of color measurement of holographic printed matter. To resolve this problem of laser rainbow cigarette packet product, a special light source--dome light which is special for holographic printed matter is designed, and a 6-channel line scanning charge coupled device (CCD) imaging system based on the dome light is constructed. In the environment, color measurement for laser rainbow holographic printed matter is made by using spectral reconstruction method based on principal component analysis technique. The experiments show that in spectral reflectance reconstruction, proposed method of color measurement has the characteristics of high-precision, and is effective to solve the problem of color measurement of laser rainbow holographic printed matter.
