The amount of light that passes through paper is known as what?

Explanation:
Opacity is the property that describes how much light is blocked by a sheet of paper. It tells you how much you can see through the page—high opacity means little light passes through and minimal show-through, while low opacity means more of the back side is visible. This is different from basis weight, which measures how heavy the paper is per area; grain direction, which deals with fiber alignment and folding behavior; and PMS, which is a color-matching system. Opacity can be increased by using a thicker sheet and fillers like titanium dioxide, and it is influenced by ink coverage and the paper’s whiteness or brightness. For double-sided printing, higher opacity helps readability by reducing show-through.
