Paint hiding power test card stock

The paint hiding power test card features a black-and-white background. After applying the test paint, the ability to obscure the black-and-white boundary is observed. The contrast ratio is used to reflect the coating's effectiveness in covering the underlying color, serving as a reference for quality control in paint production and application thickness.
Selection
When selecting, ensure the cardboard substrate is flat and texture-free, with clear boundaries between black and white areas. The coating should have moderate absorbency to avoid excessive penetration. Consider the size specifications required by testing standards to ensure compatibility with reflectance instruments. Prioritize solvent-resistant cardboard to accommodate different coating systems.
