                              網版印刷的階調范圍與膠印有著很大的不同,這是印刷方式所決定的。膠印的網點在制版和印刷時一般都能較完整的反映出來,所以膠印的階調范圍一般在5%-95%之間。

                                但網版印刷由于受到網版的網絲影響,制版時高調和低調的網點有可能被網絲遮擋住,印刷時無法印制出來,所以容易形成高調或低調部分的網點丟失,高調部分變成大面積的空白,低調部分變成大塊實地而影響過渡效果。

                                所以一般來說,網版印刷在加網線數60線一下時,階調范圍10%-90%在之間,而加網線數在60線以上時,可控制在15%-85%之間。
