特种纸印刷注意事项

文章作者:华政印务 发布时间:2021-11-17
特种纸是指具有特殊用途的、产量比较小的纸张,是各种特殊用途纸或艺术纸的统称。由于特种纸表面的平整度和吸墨性与哑粉纸、铜版纸有很大区别,所以使用特种纸进行印刷时,机长要提前做好准备工作,那么特种纸印刷有哪些“道道儿”呢?本文将为您一一呈现。
Special paper refers to the paper with special purpose and small output. It is the general name of all kinds of special purpose paper or art paper. Because the flatness and ink absorption of the surface of special paper are very different from those of matte paper and coated paper, the captain should make preparations in advance when using special paper for printing. What are the "ways" of special paper printing? This article will show you one by one.
1.在油墨中添加干燥油
1. Add dry oil to the ink
表面特别光滑的特种纸,吸墨性较差,印刷时稍不留意就会粘脏。所以选用快干型油墨更好,并且要在各色油墨中添加能加速油墨快速干燥的干燥油,提高油墨的干燥速度,避免印刷时出现纸张表面粘脏故障。
Special paper with particularly smooth surface has poor ink absorption, and it will be dirty if you don't pay attention to it when printing. Therefore, it is better to select quick drying ink, and add drying oil that can accelerate the rapid drying of ink in various colors of ink, so as to improve the drying speed of ink and avoid the problem of paper surface sticking during printing.
2.严格控制厂房温湿度
2. Strictly control the temperature and humidity of the plant
与铜版纸、哑粉纸相比,特种纸的填充料和成分不同,如果控制不好厂房温湿度,容易导致纸张变形和套印不准。通常,使用特种纸进行印刷时,厂房温度应控制在20~24℃,湿度控制在十分之六七。当厂房湿度小于十分之四时,有些特种纸10分钟左右就会发生纸边卷曲,容易造成印刷输纸困难。所以纸张裁切后应立即用塑料薄膜缠好放置在温湿度适宜的库房里,同时还要注意保持印刷厂房温湿度稳定适宜。
Compared with coated paper and matte paper, the filler and composition of special paper are different. If the temperature and humidity of the plant are not well controlled, it is easy to cause paper deformation and inaccurate overprint. Generally, when printing with special paper, the plant temperature should be controlled at 20 ~ 24 ℃ and the humidity should be controlled at 67 / 10. When the humidity of the plant is less than 4 / 10, some special paper will curl around the paper edge in about 10 minutes, which is easy to cause difficulties in printing and paper feeding. Therefore, the paper should be wrapped with plastic film immediately after cutting and placed in the warehouse with appropriate temperature and humidity. At the same time, pay attention to maintaining the stable and appropriate temperature and humidity of the printing plant.
3.不同特种纸的给墨量有所不同
3. The ink feeding amount of different special paper is different
对于表面光滑程度较高的特种纸,如珠光纸、印易冰白纸、高彩滑面纸、酷客冰白纸等,印刷时墨色不宜太饱和,使用正常的给墨量即可。因为纸张表面越光滑,吸墨性越差,给墨量越大,越容易造成纸张背面粘脏。
For special paper with high surface smoothness, such as pearlescent paper, easy to print ice white paper, high-color smooth paper, KUKE ice white paper, the ink color should not be too saturated during printing, and the normal ink feeding amount can be used. Because the smoother the paper surface, the worse the ink absorption, the greater the amount of ink, and the more likely it is to cause the back of the paper to be sticky and dirty.
表面较粗糙的特种纸,如手揉纸、金太阳双胶纸、檀风宣纸、牛皮纸、高歌映画纸、东方书写纸、道林纸等,摸起来有纹路、不光滑。印刷时,这种纸张吸墨性较好,油墨会透到纸张的纹路里,待油墨干燥后,用肉眼观察到的印品颜色会变浅,印刷质量也会降低。所以,对于这种特种纸,印刷时的给墨量要比平时更大一些,对饱和度的要求也更高。
Special paper with rough surface, such as hand kneading paper, golden sun double offset paper, sandalwood wind rice paper, kraft paper, gaogeying painting paper, Oriental writing paper, Daolin paper, etc., has lines and is not smooth. When printing, this paper has good ink absorption, and the ink will penetrate into the lines of the paper. After the ink is dry, the color of the printed matter observed by the naked eye will become lighter and the printing quality will be reduced. Therefore, for this special paper, the ink supply during printing is larger than usual, and the requirement for saturation is also higher.
