What type of paper is most commonly used for watercolor or ink washes due to its pronounced surface texture?

The most commonly used type of paper for watercolor or ink washes that features a pronounced surface texture is rough paper. Rough paper has a highly textured surface, which helps to retain water and pigment, allowing for more varied and dynamic brush strokes. This surface texture is essential for achieving different effects in watercolor and ink wash techniques, as it creates interesting patterns and enhances the visual quality of the artwork.

While hot pressed paper has a very smooth surface, it may not hold water or pigment as effectively, making it less suitable for techniques that require texture and depth. Graphite paper, used primarily for transferring images, is not designed for watercolor work. Cold pressed paper, although commonly used for watercolors, is not as textured as rough paper and typically has a softer texture that may not provide the same dramatic effects. Thus, rough paper stands out as the preferred choice for artists seeking the unique qualities its texture offers in watercolor and ink wash applications.
