vesivärvipaber

Vesivärvipaber, also known as watercolor paper, is a specialized type of paper designed to withstand the unique demands of watercolor painting. Unlike regular paper, watercolor paper is typically made from 100% cotton or a blend of cotton and wood pulp, which gives it greater absorbency and durability. The fibers in cotton are longer and stronger than those in wood pulp, allowing the paper to hold a significant amount of water without disintegrating or buckling excessively.

The surface of watercolor paper is often treated with sizing, a gelatinous substance that controls the absorption rate of water and pigment. This sizing prevents the paint from spreading too rapidly into the paper and allows for greater control over washes and details. The texture of watercolor paper can vary, with cold-press paper having a medium texture, hot-press paper having a smooth surface, and rough paper offering a pronounced tooth. These different textures affect how paint sits on the surface and the visual effect achieved.

Watercolor paper comes in various weights, measured in grams per square meter (gsm) or pounds per ream. Heavier papers, typically 300 gsm (140 lb) and above, are more resistant to buckling when wet and are often preferred for more intricate or layered watercolor techniques. Lighter papers may require stretching before use to minimize warping. The choice of watercolor paper can significantly influence the outcome of a painting, affecting color vibrancy, blending capabilities, and the overall aesthetic of the artwork.
