Oblique stripe opacity chart

Oblique hiding power paper is a testing substrate with a specific oblique texture on its surface. By evenly applying coatings or inks onto it, the visual interference effect of the oblique pattern background is utilized to evaluate the coating's ability to conceal underlying patterns. It is used in the printing and coating industries to test the hiding performance of products, helping determine whether the coating thickness or pigment dispersion meets the required hiding standards.
