What Is Offset Paper (Uncoated Woodfree)?
Papier offset (also known as woodfree uncoated paper or bond paper) features a natural, non-coated fibrous surface with open paper pores. It is engineered specifically for exceptional ink absorption, crisp text legibility, and effortless handwriting receptivity. Without a synthetic gloss coating, offset paper provides a soft, warm tactile feel and a glare-free viewing experience.
Offset paper is the primary choice for trade novels, mémoires, cahiers, planificateurs, school textbooks, technical training manuals, and legal documents where long reading sessions and handwriting comfort are essential.
