多色胶印机印刷压力的单独修正

分别在相同和不同印刷压力状态下进行印刷试验,得到各色组在相同印刷压力下不同网点百分比的网点增大值和在不同印刷压力下相同网点百分比的网点增大值,分析比较各色组网点增大值与印刷压力的大小关系,从而得到各色组合理的印刷压力修正值,使得各色机组的印品网点增大值一致。

Separate Modification of Printing Pressure of Multicolor Offset Press

Printing experiments were carried out under the same and different printing pressures.The dot gains of different dot percentages under the same printing pressure and that of the same dot percentage under different printing pressures were obtained through testing the prints.By analyzing relationships between the dot gains and printing pressures,the reasonable adjustments of printing pressure on each printing unit were determined to ensure consistent dot gain on printing products.
