Printing and environmental sustainability

The impact of the printing process on the environment is significant. This paper explores the voltage of reverse roller in indirect electrophotography printing in the field of 0V to -250 V on the life end of the printed products through the efficiency of recycling. In addition, the quality of color reproduction is discussed. For the printing is used: uncoated woodfree paper, double-sided coated paper and Soho coated paper. Characteristic of the results of image analysis handsheets made from recycled fibers prints obtained by changing the voltage of reverse rollers from 0 to -200V is reduced in the total dirt spot number and increasing in the dirt spot area. The efficiency of recycling is the highest for printing on uncoated paper, then on Soho coated paper, and the worst on double-sided coated paper. The quality of fullcolored prints observed through the volume gamut of prints gives reverse results. This is just part of a comprehensive study involving all six separate stages of electrophotography printing synchronal performed. In this study the use of experimental design and creation of statistical models in the direction of optimization process and environmental sustainability follows.
