The Short Answer

The surface texture of paper (especially drawing paper) is called *tooth*, and it heavily affects the mark that your drawing instrument leaves. A rougher (coldpress) tooth will more readily absorb watercolors, for example, which will prevent them from running or from blotting, giving you crisp and clean lines. You can even apply multiple layers of watercolors and pastels without worry! A smoother (or hotpress) paper will be more useful for smearing things like charcoal, when you want that smudgy, messy look. These are also great for smooth, clear, clean pencil lines. For clean, crisp lines, go for rougher papers. For a little bit of bluriness, go for something smoother.
