The process of preparing watercolor paper for painting by uniformly expanding and securing it is a crucial step for artists seeking to achieve smooth, even washes and prevent buckling or warping during the painting process. This preparatory measure involves wetting the paper, allowing it to expand fully, and then affixing it to a rigid support, ensuring that it dries taut and flat.
This pre-treatment is essential for preventing the paper from distorting as it absorbs water from the watercolor paints. By creating a stable and tensioned surface, the artist can achieve greater control over the flow of paint, reduce the likelihood of unwanted textures or pooling, and preserve the integrity of the final artwork. Historically, various methods have been employed, reflecting the evolution of artistic techniques and materials.
