Paper Marbling

マーブリング / historical–present / Technique / Decorated Paper

Transfers the flow of colors floating on liquid to paper exactly once — an order that cannot repeat.

Fluid veins / Comb patterns / Multicolor swirls / Every sheet different

Dictionary entry

Best used for: A one-of-one feel for bindings, packaging and grounds · Organic counterpoint to strict typesetting
Type: A composed serif or small sans that doesn't fight the pattern
Composition: Full-bleed pattern needs one clear text plane; partial use should show the cut edge
Material: Two to four flowing colors, the paper's absorbency, slight unevenness
Caution: A digital swirl is no substitute. Understand the liquid's flow, the comb, the chance of transfer.
