【摘要】 包装用纸张白度是影响其印刷品色彩还原的主要因素,白度越高,色彩还原效果越好。但是高白度纸张印品对眼睛的光刺激不断被读者诟病。针对此问题,本文预研究纸张白度与眼舒适度,及纸张白度与印刷质量之间的关联性,最终找出可满足眼舒适及印刷质量要求的合适白度范围值。结果发现,随着包装用纸张白度增加,易导致视疲劳。另外,白度为89.4%及96.2%的纸张印刷质量相对较好,而白度为84.6%的纸张印刷质量较差,但差距不大。结果表明纸张白度在84.6%-89.4%之间时,人眼不易疲劳且印刷质量较好。此研究为印刷包装企业选择兼顾护眼及印刷质量包装用纸张提供理论依据,为人眼保护事业做出贡献。更多还原

【Abstract】 Whiteness of wrapping paper is the main affecting factor of printed matter color rendition,the higher the whiteness,the better the results of color rendition.But the result of pursuiting high whiteness is that human eyes are harmed by the photic stimulation of paper-based printed matter.To solve the mentioned above problem,this paper preliminary researches the correlation between paper whiteness and asthenopia,the correlation between printing quality and paper whiteness,for finding out appropriate whiteness that can meet the eyes comfort and have better printing quality.Results show the asthenopia occurs easier as whiteness of wrapping paper increases.Besides,the paper samples with the whiteness values as 89.4%and 96.2%have the better printing quality,and the samples with the whiteness values as 84.6%have the worse printing quality relatively,but the quality gap is not big.Results show the whiteness of samples is between 84.6%and 89.4%,human eyes don’t feel asthenopia and the printing quality is better. The research results can provide the theoretical basis for printing and packaging enterprises to choose paper which are suitable for printing packing and have eye-protection function,and contribute to the human eye protection.更多还原
