浅谈油墨调配
油墨调配时,应掌握一个原则,即在浅色墨中逐渐加入深色油墨。切不能先取深墨后加浅色墨,因为浅色油墨着色力差,如果用在深色油墨中加入浅色油墨的方法去调配,不易调准色相,往往使油墨量越调越多,这是不可取的。
Ink, should adhere to one principle, namely in the light coloured ink gradually to dark ink. The cut can not be a deep ink and light coloured ink, light ink color force is poor, if the method with light colored ink in the dark ink to deployment, uneasy to adjust hue, often make the transfer more quantity of ink, it is not desirable.
当油墨色相调到原稿色相差不多时,即可用印刷纸刮墨色样后,与原稿进行对比,如还有色偏则加色纠正,直到符合印刷样稿。
When the ink color to the original color almost, can printing paper scraping ink samples, compared with the original, such as colored offset plus color correction, until with printing sample.
油墨色相调准后即可算出它们各自的份量,以便按比例进行批量的调配。如果采用三原色墨调配深色油墨,应掌握它们的变化规律,以提高调墨效果。
Ink color alignment can calculate their weight, so according to the proportion of batch deployment. If the use of the three primary colors of ink mixing dark ink, should grasp the changes of them, to improve the ink effect.
如:三原色油墨等量混调,所得到的色近似墨;三原色油墨中的两种原色等量或不等量混调,可获得各种间色,其色相偏向于含量比率大的色果;三原色墨分别以各种比例混调,可得到多种复色;任何色油墨中加入黑墨,它的明度必然下降以致色相变深暗。若加入白墨其明度则提高。
