The duplication of art works has been made for wide distribution and profit from long time ago. With material duplication due to recent development of digital duplication media its concept was intervened in art works and the meaning gets expanded more. In this thesis, I will review on the concept of recently marked arts duplication connecting with modern mass culture, compare with duplication of machinery duplication era and research on the features to establish in new way. After all, the duplicational features of digital art works got deeply connected with the characteristics of generalized modern digital mass culture for duplication. In previous times old-fashioned machinery duplication such as pictures, woodblock prints and films played their roles as democratic and social value of art works and now it will be enough to say that the modern digital art works could be developed to be non-materialized factor of art works with the concept of duplication as well as duplication of objects just like previous cases. Besides duplicational factors derived spatial and emotional effects with visional sympathy in existing machinery duplication era and could have verified that the object for duplication was transferred from minor commercial producers to major audience.
