The digital stencil duplicating system is a print method with low environmental impact. In this study, the environmental impact was quantitatively evaluated by inventory analysis of life cycle. For the life cycle inventory analysis, used was the hybrid of Input - Output Analysis and Process Analysis, which is the most advanced method for calculating environmental impact. By this hybrid method, the environmental impact of digital stencil duplicating system was calculated efficiently and accurately. The major conclusions ate: (1) Owing to the long life span of the digital stencil duplicator, the CO2 emission per sheet of printing paper (B4 side) is as low as 0.54 g. And thus, it is quantitatively proved that the digital stencil duplicating system is such a system that gives low environmental impact. (2) The quantity of CO2 emitted from the digital stencil duplicating system is mainly out of the printing paper. (3) The quantity of CO2 emitted out of ink made of soybean oil is roughly the same as that out of ink made of mineral oils, taking no account of the quantity of CO2 absorbed by the soybean during its growth period.
