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

Abstract

An optically readable code support to be associated with or be part of a capsule indented for delivering a beverage in a beverage producing device by centrifugation of the capsule, the support comprising at least one sequence of binary 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 binary symbols are essentially formed of light reflective surfaces and light absorbing surfaces. The code support preferably comprises a base structure extending continuously at least along said sequence of symbols and discontinuous discrete light-absorbing portions locally applied onto or formed at the surface of said base structure; wherein 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: said 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.
