The traditional batik stamp (canting cap) is relatively expensive tool, made of copper. The lack and high price of copper made it difficult for batik stamp crafter to market their products, and made alternative materials from wood and paper/cardboard. The weakness of wood and paper stamp is that the resulting rough motifs and not long lasting. The use of used can is environmentally friendly, assure sustainability by recycling waste of cans which causes environmental problems. This study departs from research on the innovation of Cantik batik stamp made of biscuit can waste, focusing on the economic aspect of the innovations. This analysis was important to see the advantages and or weaknesses of the can stamp, as a basis for applying the research product in the batik stamp rafter community. Descriptive research was conducted for cost calculation, analysis of selling power, and service life. The cost of can batik stamp found cheaper than copper stamp, since the materials is low cost, though 21% copper content was still needed for isen-isen, ganjelan, and bajelan part. However the labor processing cost was equal. The processing time efficiency was lower, while level of difficulty in processing was higher, because cans are harder and more difficult to shape and cut compare with copper. The durability of the can batik stamp was lower than copper, because can is easily oxidized and corrosive, so it will be more difficult to maintain. The risk of rust can be reduced by processing the final stamp in hot gondorukem (resina colophonium). For long lasting product, the can stamp has to storage in a dry and low humidity place, in hung position. © Published under licence by IOP Publishing Ltd.
