Abstract

The printing sector is gaining new dimensions with developments in printing systems. Especially, innovations in electrophotographic printing system are moved to different dimensions of the printing sector. In terms of preference, electrophotographic printing have not passed in front of the offset printing yet, new use areas and the integration with other printing systems have been expanded the fields of use of electrophotographic printing systems. Recently, it has become fast continues studies intended for reducing the cost of both substrates and toner and other raw materials in electrophotographic printing system, which is more and more preferred in less printing circulation.
Although, electrophotographic printing has many advantages, the difficulties of recycling of printed digital papers is a major disadvantage. While printing inks used in offset printing or gravure printing during printed paper recycling can easily be remove from paper, toner used in electrophotographic printing can not be completely separated from the paper. Because of the fact that they stick on the paper surface, the quality of paper obtained after recycling are decreased.
The primary purpose of this study is to understand the structure of the toners used in digital printing. The study will be examined in two parts. In the first part, the recycling conditions of printed papers will be explained. In the second part, the impact on recycling of toners used in electrophotographic printing will be considered.
