Abstract
An optically readable code support to be associated with or be part of a capsule intended for delivering a beverage in a beverage producing device, the support including at least one sequence of symbols represented on the support so that each symbol is sequentially readable by a reading arrangement of an external reading device while the capsule is driven in rotation along an axis of rotation. The symbols are essentially formed of a succession of light reflective surface portions and light absorbing surface portions. The light absorbing surface portions provide a lower light-reflective intensity than the light-reflective surface portions, and the code support includes at least one base layer extending continuously at least along the sequence of symbols. The light-absorbing surface portions are roughened surface portions having a higher rugosity (Rz) than the light-reflective surface portions.
