经涂布的衬底和系统以及其制造方法
摘要：
一种经涂布的纸板(100)，其包含∶基础衬底(102)，使用TAPPIT452测知，所述基础衬底的亮度为约65或更小；和位于所述基础衬底的至少一侧上的涂布物(104)，其中所述基础衬底包含∶一个或多个包括白色填料的不透明层(114)，其中所述不透明层覆盖所述基础衬底，使得所述基础衬底透过所述不透明层的可见度基本上被消除；覆盖所述不透明层的屏障层(116)；其中所述屏障层基本上防止水性流体接触所述不透明层，并且其中所述经涂布的纸板在所述基础衬底具有所述涂布物的侧面的亮度使用TAPPI T452测知为约65或更大，并且在所述基础衬底具有所述涂布物的侧面的湿亮度下降值使用湿亮度下降值测试测知为约30或更小。
摘要（英）：

A coated paperboard (100) comprising: a base substrate (102) having a brightness of about 65 or less measured using TAPPI T452 and a coating (104) on at least one side of the base substrate, wherein the base substrate comprises: one or more opaque layers (114) including a white filler, wherein the opaque layer covers the base substrate so that visibility of the base substrate through the opaque layer is substantially eliminated; a barrier layer (116) covering the opaque layer; wherein the barrier layer substantially prevents aqueous fluids from contacting the opaque layer, and wherein the coated paperboard has a brightness on the side of the base substrate with the coating of about 65 or more measured using TAPPI T452, and a wet brightness drop, on the side of the base substrate with the coating, of about 30 or less, measured using the wet brightness drop test.
