Plainpaper

Plainpaper is a general term used to describe standard uncoated paper intended for everyday writing, printing, and copying. It is not a brand; rather it denotes a class of papers that lack surface coatings designed to alter ink drying or glare, making it broadly compatible with pencils, ballpoint pens, and a range of printing inks.

Composition and varieties: Plainpaper is typically made from cellulose fibers derived from wood pulp or recycled materials and may include fillers such as kaolin or clay to improve smoothness and brightness. The surface is usually smooth and non-glossy. Variants are categorized by color (such as white, off-white, or tinted) and by weight, which is measured in grams per square meter (gsm). Heavier grades provide greater opacity and stiffness, while lighter grades are more economical for everyday tasks.

Production and properties: In a paper mill, pulp is refined, formed into sheets, pressed to control thickness, and dried. Uncoated plainpaper lacks the coatings found on specialized stock, which affects ink behavior, drying time, and reproduction quality. Practical properties include writeability, ink bleed resistance, and opacity, which vary with fiber content, finish, and weight.

Applications and standards: Plainpaper is widely used for office documents, drafts, and casual printing where high-gloss finishes are unnecessary. It is compatible with a wide range of printing and copying equipment. Standards for brightness, whiteness, and opacity help define suitability for different tasks, while consumer and professional grades meet varying performance expectations.

Environmental considerations: Many plainpapers incorporate recycled content and are produced from responsibly managed forests. Certifications from organizations such as FSC or PEFC help indicate responsible sourcing and sustainable production practices.
