Is cotton rag paper better than wood pulp for prints?

For archival fine-art prints, yes. Wood pulp contains lignin, which reacts with light, oxygen, and humidity over decades to produce the yellowing and brittleness familiar from old newspaper. Cotton has no lignin, so a cotton rag print stays bright and dimensionally stable for centuries under normal display conditions. Wood pulp is fine for posters; cotton (or α-cellulose) is the standard for fine art.

Is α-cellulose paper the same as cotton rag?

Functionally similar, chemically different. Both are long-fibre and lignin-free, so they share the archival profile. Cotton rag is made from cotton fibre; α-cellulose is made from wood pulp that's been refined to remove the lignin. High-grade α-cellulose (the Hahnemühle papers, for instance) performs identically to cotton over typical display lifetimes.

Do you print on cotton rag?

We use Hahnemühle German Etching 310gsm, which is α-cellulose rather than pure cotton rag. The archival profile is functionally identical — Wilhelm-rated for 100+ years under glass. The choice between cotton and α-cellulose comes down to surface character: German Etching has a soft velvety matt finish that suits a wider range of imagery than the smoother surface of most cotton papers.

Definition

Paper made from 100% cotton fibre rather than wood pulp. Acid-free, dimensionally stable, and the most archival paper substrate available.

Cotton rag — sometimes “100% cotton” or just “rag paper” — is paper made from cotton fibre rather than the wood pulp used in everyday printing paper. The fibre is longer, naturally acid-free, and chemically more stable than wood-based paper, which is why cotton rag is the substrate of choice for archival fine-art prints, watercolour, and printmaking.

Wood-pulp paper contains lignin — the natural polymer that holds cellulose fibres together in living trees. Lignin is acidic and reacts with light, oxygen, and humidity over decades to produce the yellowing and brittleness that’s familiar from old newspaper. Even paper marketed as “acid-free” wood pulp will eventually shift colour. Cotton has no lignin, so a cotton rag print stays bright and dimensionally stable for centuries under normal display conditions.

A few practical features worth knowing. The surface — cotton paper has a softer, more matt surface than coated wood-pulp paper, so prints sit into the surface rather than on top of it, giving a slight three-dimensional quality. The weight — fine-art cotton paper is heavy, typically 200 to 350gsm, with substance under the hand and no tendency to warp when framed. The tone — most cotton rag paper is bright but not blue-white; the natural tone is a faint warm cream that flatters most palettes. The cost — cotton rag is significantly more expensive to manufacture than wood pulp, three to five times the price of a comparable wood-pulp sheet at the same size.

Hahnemühle’s α-cellulose papers — including the German Etching 310gsm we use — aren’t pure cotton rag, but they’re functionally archival: high-grade α-cellulose has the same long-fibre, lignin-free profile and behaves identically over time. The choice between cotton and α-cellulose is largely about surface character rather than longevity.
