An encoding method for generating at least one coding (118) on an item, in particular a medical disposable item (117), is proposed. The coding (118) comprises at least one information component in encoded form. The method comprises the following steps: a) the at least one information component is converted into a code, wherein the code comprises a plurality of pairs composed of a gray-scale value and a degree of filling; b) the code is converted into an optical information component (119), in particular a two--dimensional optical information component (119), wherein the optical information component (119) comprises at least one field (164) filled with a gray-scale value up to an associated degree of filling in accordance with the plurality of pairs composed of a gray-scale value and a degree of filling; and c) the optical information component (119) is applied to the item.
Linvention concerne un procédé de codage permettant de générer au moins un codage (118) sur un article, en particulier sur un article médical à usage unique (117). Le codage (118) comporte au moins une information sous forme codée. Le procédé comporte les étapes suivantes : a) la ou les informations sont converties en un code qui comporte une pluralité de paires composées dune valeur de gris et dun degré de remplissage; b) le code est converti en une information optique (119), en particulier en une information optique bidimensionnelle (119) qui comporte au moins un champ (164) rempli, jusquà un degré de remplissage correspondant, avec une valeur de gris correspondant la pluralité de paires composées dune valeur de gris et dun degré de remplissage; et c) linformation optique (119) est appliquée sur larticle.
