Using color management systems to adjust the ink Keys at the litho offset sheet feed printing machine

Using color management systems in order to obtain uniform color production along all stages of printing production which allows: Increasing the quality of the print production. Increasing quality consistency. Time/money savings in prepress through decreased retouching of images and remaking of proofs. Time/money savings in printing through faster color ok in make-ready. The study is to find The impact of using color management systems which can be applied through all print production stages from prepress till the press stage. Adjusting ink zones on the printing machine is considered to be one of the most important factors that affect the quality of the printed color which can be an affecting factor in producing the dot gain phenomenon, and also decrease the print waste percentage. The research have been established through a number of experiments and measurements recorded in each of the extent of change.
