喷墨耗材高光相纸光泽度与视觉亮度差别的研究

Research on the difference between gloss and visual brightness of high-gloss photo paper of inkjet consumables

通过对比市售的喷墨高光耗材的光泽度和视觉亮度,发现某国产喷墨耗材光泽度高达60(60°角),进口某高光的光泽度为58(60°角),但二者在目测的情况下,进口某高光相纸的视觉亮度要高于国产某高光相纸,通过研究认为视觉亮度与20°角下的光泽度的反应基本一致;同时发现进口某高光相纸在430~470 nm范围内反射光的能量超过100%,证明了进口某高光相纸中具有某种能激发出430~470 nm范围内的光的物质;国产某高光相纸复合涂层在入射光60°角时会在第一和第二涂层界面上发生全反射,而全硅产品进口某高光相纸的反射会在涂塑层上,此时光需要2次穿透进口某高光相纸的涂层,能量损失比国产某高光相纸多,国产某高光相纸产品在此条件下光泽度会比进口某高光相纸的涂层光泽度高。

By comparing the gloss and visual brightness of commercially available inkjet high-gloss consumables,this paper finds that the gloss of a domestic inkjet consumables is as high as 60(60 degree angle),and the gloss of an imported high-gloss is 58(60 degree angle),but in the case of visual inspection,the visual brightness of an imported high-gloss photo paper is higher than that of a domestic high-gloss photo paper,and through research,it is believed that the reaction of visual brightness and gloss at a 20-degree angle is basically the same;At the same time,it was found that the energy of the imported high-gloss photo paper reflected light in the range of 430nm-470nm exceeded 100%,which proved that the imported high-gloss photo paper had a substance that could excite light in the range of 430nm-470nm;A domestic high-gloss photo paper composite coating will be fully reflected at the interface of the first and second coatings at an angle of 60 degrees of incident light,while the reflection of a high-gloss photo paper imported by all-silicon products will be on the coating layer,this time needs to penetrate the coating of an imported high-gloss photo paper twice,the energy loss is more than that of a domestic high-gloss photo paper,and the gloss of a domestic high-gloss photo paper product under this condition will be higher than that of the coating gloss of an imported high-gloss photo paper.
