Research on Traditional Chinese Painting Duplicate by User-defined CMYK Conduction in Photoshop

Different color separation parameters setting was studied to achieve better effect of traditional Chinese painting reproduction by user-defined CMYK conduction in Photoshop. The effects were evaluated using the "subjective judgments combined with objective line graphs analysis" method,and the objective evaluation indicators were density and gray balance. The results showed that the reasonable GCR setup would help to achieve the quantity of ink painting.
