Opacity test card paper

The hiding power test card is a standard cardboard with alternating black and white grids. After coating the paint, the degree to which the black grids are covered is observed to determine the paint's ability to conceal the underlying layer. It is suitable for quality control in industries such as paints and inks.
Selection
When selecting a hiding power test card, it is essential to consider the substrate's flatness, the clarity of black-and-white grid boundaries, and the paper's solvent resistance. The card specifications should be matched to the type of coating being tested to ensure that the results align with practical application scenarios.
