Definition

• Dappled Surface.  A background texture of sunken dots or hemispheres. Such surface texture is made with repeated use of a dapple tool in the positive model or hub. It is the opposite of pebbled surface, raised dots or tiny hemispheres (which can be made with the same dapple tool in the negative model or die). The term for a single sunken indentation is a dapple; the term for a raised dot is a boss. A dappled surface is not considered an artistic texture (but more of a mechanical surface anyone can make).
