Research on Effect of Paper Containing OBA on Color Reproduction
Abstract:
Adding Optical Brightening Agent (OBA) during papermaking has been widely used in modern papermaking industry in order to improve paper whiteness. Because of ISO standard data is based on the paper without OBA, it makes a great diversity of result in color reproduction, and causes the printing production not to meet international standards. This research contrasted ISO whiteness and chroma value of paper with different amount of OBA, analyzed spectral data and tone in color reproduction of paper with different amount of OBA, then got the law of the effect of the ratio of OBA on ISO whiteness and chroma value, and the effect on color reproduction tone level in printing process. It can provide the reference for adding OBA during papermaking.
