Opacity Opacity refers to the degree to which a material or substance blocks the transmission of light or allows objects behind it to be obscured or concealed. In the context of printing, opacity is an important property of paper, ink, and other printing materials that affects the visibility and legibility of printed text, images, and graphics. Opacity is typically expressed as a percentage, with higher opacity indicating greater light-blocking ability and less see-through or show-through of underlying layers.
Opacity is influenced by factors such as paper thickness, weight, and composition, as well as ink coverage, color density, and printing process. High-opacity papers are preferred for double-sided printing, where text and images must remain legible without interference from content printed on the reverse side. |
