The numerical value preceding the term “bright” when describing paper, particularly printer paper, signifies the paper’s reflectance. This metric quantifies the amount of light reflected off the paper’s surface. A higher number indicates a greater degree of reflectivity, resulting in a whiter and more brilliant appearance. For example, paper rated with a “96 bright” designation reflects more light than paper rated “92 bright,” leading to enhanced contrast and improved readability when printed upon.
This brightness rating is essential because it directly impacts the visual appeal and legibility of documents. Paper with increased brightness enhances the contrast between the ink and the paper, making text and images appear sharper and more vibrant. Consequently, utilizing brighter paper can improve the professional presentation of printed materials, which is particularly crucial for reports, presentations, and marketing collateral. Historically, the development of brighter paper involved advancements in pulp bleaching processes, aiming to increase the paper’s whiteness and reflectivity without compromising its structural integrity.
