彩色印刷的油墨知识

印刷设计在承印物上的三原色油墨的密度正确和平衡与否与印刷设计人员有直接的关系。印刷设计操作人员虽然只能在有限的范围内测量、设置油墨密度,不过这些密度范围可以帮助印刷设计人员获得较大范围的叠印油墨色,不论油墨是否透明,或承印物是否纯白。在印刷设计中我们可以十分方便地在各种相关的出版物上找到这些密度范围:如FIRST和SWOP标准中都有说明。
Three color printing ink in the substrate of the printed design density of correct and balanced or not and the printing designers have a direct relationship. Printing design operator although only in a limited range of measurement, set the ink density, but the density range can help the designer to obtain printing overprint ink color range, regardless of whether the ink substrate is white or transparent. In printing design we can easily find these density ranges in various related publications such as FIRST and SWOP standard.
印刷设计中根据指导说明上的油墨密度范围可以用于任何油墨叠印顺序,即YMC、YCM、CMY、CYM、MCY或MYC。但是印刷设计上是否每一种顺序都产生同一种颜色呢?其实不是。
According to the instructions in the design of printing ink density range can be used for any ink overprint sequence, namely YMC, YCM, CMY, CYM, MCY or MYC. But is there the same color in each of the printed design?.
即使实地密度被控制在绝对值时,印刷设计中每种叠印顺序也会产生红、绿、蓝的不同叠印色,因为每种印刷设计上印刷油墨配方有各自不同的属性,比如影响遮盖率的油墨不透明度。所以,先印刷(印刷设计)的油墨干燥膜层的表面能将影响后印刷(印刷设计)的湿油墨的附着特性。
Even if the field density is controlled in absolute value, printing design each overprint sequence will produce different superimposition of red, green and blue, because each printing design printing ink formulations have different attributes, such as the impact of the ink transparency cover rate. Therefore, the first printing (printing design) ink drying of the surface of the film can affect the printing (printing design) of the wet ink adhesion characteristics.
