Such has discontinuous areas soaked in a proofing substance, preferably polyvinylidene chloride (PVDC) which is impermeable to both gases and liquids, and thereby on establishing areas representing a logotype, a text, an anagram or any other design with said proofing substance, when the cellulose casing is later filled with the meat emulsion, and the same is smoked or coloured through the cellulose casing, the proofing substance will provide a barrier to such later soaking thereby for the smoke or colouring to cross only those areas of the cellulose casing which have not been treated with the proofing substance, that are then coloured, providing a background upon which "printed devices" appear that are formally, dimensionally and positionally coincident with those existing on the cellulose casing, when the casing is finally removed, such "printed devices" being duly established upon the sausage proper. <IMAGE> |
