Abstract: |
The goal of the work proposed in this dissertation is to develop a new method for theAbstract: Mineral fibers with different addition amount were incorporated into waste paper pulp to makechrominance measurement and control of coloring images printed on holographic paper. Since the specialAbstract: Mineral fibers with different addition amount were incorporated into waste paper pulp to makefeature of the holographic paper, it can reflect rainbow colors when it is in light, and the chrominance andAbstract: Mineral fibers with different addition amount were incorporated into waste paper pulp to makethe density of reflected light would changed along with the observation angle changing, so when ink isAbstract: Mineral fibers with different addition amount were incorporated into waste paper pulp to makeprinted, the chrominance and the quality of the products are difficult to control. In this paper, we followedAbstract: Mineral fibers with different addition amount were incorporated into waste paper pulp to makethe convention of radiometry, derived the light distribution regular model of the interaction of light when itAbstract: Mineral fibers with different addition amount were incorporated into waste paper pulp to makecoated on holographic papers, and proposed a new method to detect the chrominance information byAbstract: Mineral fibers with different addition amount were incorporated into waste paper pulp to makechanging the illumination condition. Then we established a quality-judging system on the basis ofAbstract: Mineral fibers with different addition amount were incorporated into waste paper pulp to makechromatics. Finally, experiments show that our method used can detect color information of the coating,Abstract: Mineral fibers with different addition amount were incorporated into waste paper pulp to makeand the quality can be easily controlled
