The tactile quality of a surface or the representation of such a surface quality, is it’s texture. While tactile textures are real textures (which you can feel), they can be imitated as illusionary visual textures on computer screens, giving the impression of real life textures.
Graphic designers need to be aware of all the textures available to them. Paper has tactile texture. Inks and varnishes can create tactile textures. Visual textures, including indirect marks like rubbings and blottings, and direct marks like the ones in the following exercise, should become part of any designer’s vocabulary.
A rubbing effect can be made by following this Photoshop tutorial (http://www.escrappers.com/rubbings.html).
