山东包装Betway login的光泽如何进行提升?

来源:http://www.xinfengyinshua.cn/   发布时间:2020-11-13
在同样纸张、油墨的条件下,由于操作工艺中存在问题,往往Betway login后成品光泽相差较大。在不考虑印后上光处理的前提下,怎么来提高山东包装Betway login的光泽呢?下面我们就一起来看一下。
Under the same conditions of paper and ink, due to the problems in the operation process, the gloss of the finished product after printing is often quite different. How to improve the gloss of Shandong packaging printing without considering the post press polishing treatment? Let's take a look at it.
1.改进酸性润湿液。我国沿用几十年的酸性润湿液,以铬酸、磷酸为主,虽经冲淡,但PH值仍在3.5~5.6之间。酸性越强,对油墨连结料和颜料的分解力、腐蚀力越大,致使印迹膜面粗糙,降低了光泽。
1. Improve the acid wetting solution. The acid wetting solution which has been used for decades in China is mainly chromic acid and phosphoric acid. Although diluted, the pH value is still between 3.5 and 5.6. The stronger the acidity, the greater the decomposition and corrosion of ink binder and pigment, resulting in rough surface of imprinted film and reduced gloss.
2.降低油墨乳化度。山东包装Betway login中的油墨乳化过度大都是操作中水大墨多造成的,印迹看上去墨层很厚,但油墨分子成了水包油的状态,干燥后光泽性极差,而且还会产生一系列其它故障。水大墨多是山东包装Betway login中最犯忌的做法,要改变这种状况。    3.正确使用燥油。对于高级的亮光快干油墨,在温、湿度正常的情况下,自身已有足够的干燥能力。如遇以下情况应加放燥油:一是在冬季温、湿度偏低的情况下;二是油墨内须添加防粘剂、去粘剂、薄调墨油等的情况下,都应加放燥油。在山东包装Betway login操作中,正确地使用燥油,对于成品形成光泽非常有利。这是因为纸张吸收连结料需要一定的时间,在此过程中,尽快使连结料凝聚,直至结膜干燥,是成品光泽好的关键。
2. Reduce the emulsion of ink. The excessive emulsification of ink in Shandong packaging printing is mostly caused by too much water and ink in operation. The ink layer appears to be very thick, but the ink molecules become the state of oil in water. The gloss after drying is very poor, and a series of other faults will occur. Water and ink is the most taboo practice in Shandong packaging printing. We should change this situation. 3. Use dry oil correctly. For advanced light fast drying ink, under normal temperature and humidity, it has enough drying capacity. In case of the following circumstances should be added dry oil: first, in the winter temperature and humidity is low; second, the ink must be added in the case of anti adhesion agent, anti adhesion agent, thin inking oil, etc., should be added dry oil. In Shandong packaging printing operation, the correct use of dry oil is very beneficial to the gloss of finished products. This is because it takes a certain time for the paper to absorb the binder. In this process, it is the key to make the binder agglomerate as soon as possible until the conjunctiva is dry.

4.注意喷粉。喷粉同油墨一样,也会产生凝聚,特别是密封不好的袋装或桶装,喷粉受潮后,凝聚成较大的颗粒,喷到湿墨印迹上,使墨层表面结膜粗糙,降低了原有的光泽,因此喷粉要注意防潮。另外,喷粉装置的机构上有加热装置,在使用喷粉时应加以检查,加热装置是否失灵。
4. Pay attention to powder spraying. Like ink, dusting can also produce condensation, especially in bags or barrels with poor sealing. When the powder is damped, it will agglomerate into larger particles, which will be sprayed on the wet ink imprint, making the surface of the ink layer rough and reducing the original luster. Therefore, attention should be paid to moisture-proof in powder spraying. In addition, there is a heating device on the mechanism of the powder spraying device, which should be checked when using the powder spraying device to see if the heating device fails.
5.正确调节机器。山东包装Betway login的印迹墨层厚度是否达到标准,对于光泽也有影响。例如压力调节不良,网点扩大率高,墨层厚度达不到标准,成品光泽就稍差。因此,要把压力调整好,使网点的扩大率控制在15%左右,所印的产品墨层既厚实,层次又拉得开,光泽也有了。
5. Adjust the machine correctly. Whether the thickness of imprinted ink layer of Shandong packaging printing meets the standard also has an impact on the gloss. For example, poor pressure regulation, dot expansion rate is high, ink layer thickness can not reach the standard, the finished product luster is slightly poor. Therefore, to adjust the pressure, so that the dot expansion rate is controlled at about 15%, the ink layer of the printed product is thick, level and open, luster also has.
6.加凡立水(0号油)。这种油粘度很大,本身稠厚,可调节山东包装Betway login的油墨浓度,使稀墨变稠,增加印品光泽度。
6. Garfanlishui (No.0 oil). This kind of oil is very viscous and thick. It can adjust the ink concentration of Shandong packaging printing, thicken the thin ink, and increase the gloss of printed matter.
7.加入亮光浆。亮光浆由光泽度很高的原材料加工而成,可增加油墨的光泽,但用量不宜过大,否则会降低油墨的干燥速度,出现粘脏、拉丝现象,影响光泽度。
Add light to the light. Glossy paste is processed from raw materials with high gloss, which can increase the luster of ink, but the dosage should not be too large, otherwise it will reduce the drying speed of ink, sticky dirty, drawing phenomenon, affecting gloss.
8.加入撤淡剂。当一些油墨颜色太深不符合专色Betway login的要求时,需要将其调浅一些,这时不但可使油墨变浅,同时还能提高印品光泽。
8. Add diluent. When some inks are too dark to meet the requirements of spot color printing, it is necessary to lighten them, which can not only make the ink lighter, but also improve the luster of the printed matter.
9.加入19#树脂油。当油墨流动性与转移性能不好时,可直接调入19#树脂油,这时不但能提高油墨光泽,且不影响多色套印Betway login的进行。
9. Add 19% resin oil. When the fluidity and transfer performance of the ink are not good, the 19 ා resin oil can be adjusted directly, which can not only improve the ink gloss, but also do not affect the multi-color overprint printing.
