TAPPI的污垢图表卡由CRR胶片上的原始底片制成。这些卡在使用CUFD化学的快速访问处理器上进行处理。每张卡片都是通过一个接触框在相纸上制作的，接触框带有一个Olite光源和Olite光积分器，该积分器控制指定的特定曝光，以确保准确性和一致性。为了确保图表的准确性，每件作品都是通过使用100倍放大镜检查2个点来测量的，该放大镜的十字线（刻度）增量为5/10000mm。信用卡存货。该混浊图将与TAPPI试验方法T213、T437和T537一起使用。

TAPPI's Dirt Chart cards are manufactured from an original negative produced on CRR film. The cards are processed on a rapid-access processor using CUFD chemistry. Each card is produced on photographic paper via a contacting frame with an Olite light source and Olite light integrator which controls the specific exposure designated for accuracy and consistency. To ensure the accuracy of the charts, each piece is measured by examining the 2 dot with a 100 x magnifier that has a reticle (scale) incremented in 5/10,000mm. Card Stock. ThisOPAQUEchart is to be used with TAPPI Test Methods T213, T437, and T537.
