Eight color cells of different area were engraved in gravure plate roller by electronic engraving machine. In the same plate, we used cell angles of 30°, 45° and 60° to engrave images. Then the sheets were got through gravure proofer. Measure the densities of color cells by densitometer, weigh the ink transferred to paper, and analyze the influences of cell angles on ink transferring. It is studied that impact of different angles on tones copying is great. In the same engraving conditions, the transferred ink quantity is the largest with 45° , while it is the lest with 60° .
