Watercolor paper is specifically used for watercolor painting, characterized by its strong water absorption, durable fibers, and rich surface texture, allowing for a variety of painting techniques through different materials and processes. Depending on the material, it is divided into cotton pulp paper (natural color transition, suitable for multiple layers) and wood pulp paper (light color, fast drying). The texture is divided into rough (landscape texture), medium rough (general use), and fine (detailed depiction), with a mainstream weight of 300g to resist warping and deformation. Handmade paper focuses on durability and fine texture, while machine-made paper emphasizes cost-effectiveness, meeting the needs of large-area rendering.
