Optical readable code support and capsule for preparing a beverage having such code support providing an enhanced readable optical signal

A capsule intended for delivering a beverage in a beverage producing device by centrifugation, the capsule comprising:

• a body, a flange-like rim and 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 comprising 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,
• wherein the symbols are essentially formed of light reflective surfaces and light absorbing surfaces comprising a base structure extending continuously at least along the sequence of symbols and discontinuous discrete light-absorbing portions locally applied onto or formed at the surface of the base structure,
• the discontinuous discrete light-absorbing portions form the light-absorbing surfaces and the base structure forms the light-reflective surfaces outside the surface areas occupied by the discrete light-absorbing portions,
• the discrete light-absorbing portions are arranged to provide a lower light-reflectivity than the one of the base structure outside the surface areas occupied by the discrete light-absorbing portions,
• wherein the code support is an integral part of at least the rim of the capsule, wherein the body and rim of the capsule are obtained by forming a flat or preformed structure comprising the support.
