What are the three main categories of watercolor paper?

The three main categories of watercolor paper are distinguished by their texture and surface finish, which significantly affect the painting technique and result. Hot press paper has a smooth surface that is ideal for detailed work and fine lines; it allows for smooth washes and is excellent for techniques like layering and glazing. Cold press paper, often referred to as NOT (not hot pressed), has a semi-textured surface that provides a balance between detail and texture; it is versatile and suitable for both detailed work and broader strokes, making it the most popular choice among watercolor artists. Rough paper features a pronounced texture that can enhance the appearance of the final piece through the interplay of light and shadow, making it ideal for more expressive works or when using bold washes. These categories help artists select the appropriate surface for their style and technique, thus directly influencing the outcome of their artwork.
