Abstract: The impact of coated paper printability for image quality on the high-fidelity digital printing was studied in this paper. Compared with the traditional printing technology, high-fidelity digital printing technology is more likely to expand the color gamut, maintain the original tone linear and produce vivid image. The performance of coated paper to a large extent determines the image quality. In order to get high-quality printed matters, the mechanism of the coated paper printability influencing on the performance on high-fidelity digital printing is need to be researched in-depth. The printability of coated paper was studied from several aspects in this paper, including the structural properties, roughness, optical properties, absorption etc, the relationships between these properties and printing color, dot reproduction performance were also studied. Based on the previous theoretical and practical studies, the printability evaluation system of coated paper on high-fidelity digital printing was established initially. On digital printing, accurate color management technology also affects the printing quality as the performance of coated paper, so the advanced color management technology was also used in the current study. The results showed that the pore structure and the absorbent of coated paper were the most important factors for affecting the printing quality, and the roughness and optical properties of coated paper also had a certain impact.

Abstract: The packaging of food, beverages, tobacco, alcohol, drugs, cosmetics and other goods requires higher property of security and some special functionality such as the property of anti-bacterial; the property of anti-bacterial can be achieved by using anti-bacterial agent in the ink. In this paper, a kind of zinc-copper antibacterial agent was made by attached the metal Zn²⁺, Cu²⁺on the zeolite by ion exchange and the zeolite modified was used as a carrier; Than the zinc-copper anti-bacterial UV ink was prepared by mixing and grinding zinc-copper antibacterial agent, polyester acrylate, HDDA, TMPTA, titanium dioxide and other element of UV ink; Finally the property of anti-bacterial of Escherichia.coli(anti-E.coli) and staphylococcus aureus were tested; this paper focus on the analysis and discussion of the influence of different concentration antibacterial agent on the property of ink. This study has some practical significance to the research on the property on anti-bacterial of ink.
