用几种方法来提高印刷的光泽度

来源:http://www.xinfengyinshua.cn/   发布时间:2022-05-11
如果在市场上看到的一些光泽粗糙的产品,是因为没有做提高光泽的工作,所以要想产品更好就要适当提高光泽度,下面来讲几种方法。
If you see some products with rough luster in the market, it is because you have not done the work to improve the luster. Therefore, if you want to improve the product, you should appropriately improve the gloss. Here are several methods.
正确调整机器
Adjust the machine correctly
印刷的压印墨层厚度是否符合标准也会影响光泽度。比如压力调节不好,网点膨胀率高,墨层厚度不达标,成品光泽度稍差。压力要调好,使网点的膨胀率尽量控制在15%左右。
Whether the thickness of the imprint ink layer meets the standard will also affect the gloss. For example, the pressure adjustment is not good, the dot expansion rate is high, the ink layer thickness is not up to standard, and the gloss of the finished product is slightly poor. The pressure should be adjusted so that the expansion rate of the dot is controlled at about 15% as far as possible.
改进的酸性润湿液
Improved acid wetting solution
酸性润湿液主要是铬酸和磷酸。虽然已经稀释,但pH值仍然在3.5到5.6之间。酸性越强,油墨结合剂和颜料的分解和腐蚀能力就越大,造成压印膜表面粗糙,光泽度降低。
The acid wetting solution is mainly chromic acid and phosphoric acid. Although diluted, the pH is still between 3.5 and 5.6. The stronger the acidity, the greater the decomposition and corrosion ability of ink binder and pigment, resulting in rough surface and reduced gloss of embossing film.

注意除尘
Pay attention to dust removal
除尘粉末会像墨水一样结块,尤其是在密封不良的袋子或桶中。喷粉受潮后会结块成较大的颗粒,喷在湿墨迹上,使墨层表面粗糙,缩小原尺寸。有些光泽,所以喷涂时要注意保湿。喷粉装置的机构上有加热装置。使用喷粉装置时,应检查加热装置是否有故障。
Dust removal powder will agglomerate like ink, especially in poorly sealed bags or barrels. When the powder is wet, it will agglomerate into larger particles and spray it on the wet ink, making the surface of the ink layer rough and reducing the original size. Some luster, so pay attention to moisturizing when spraying. The mechanism of the powder spraying device is provided with a heating device. When using the powder spraying device, check whether the heating device is faulty.
正确使用干性油
Proper use of dry oil
对于明亮快干的油墨,在常温常湿下,具有足够的干燥能力。在冬季低温低湿的情况下,如需在油墨中加入防粘剂、脱粘剂、薄墨光油等,应加干性油。
For bright and fast drying ink, it has sufficient drying capacity under normal temperature and humidity. In the case of low temperature and low humidity in winter, if it is necessary to add anti adhesion agent, debonding agent, thin ink varnish, etc., dry oil should be added.
山东印刷包装认为,在印刷操作中,正确使用干性油对成品光泽的形成是非常有利的。这是因为纸张吸收粘合剂需要一定的时间。在这个过程中,粘合剂尽快凝结,直到结膜干燥,这是成品光泽度好的关键。
Shandong printing and packaging believes that in the printing operation, the correct use of dry oil is very beneficial to the formation of finished product luster. This is because it takes time for the paper to absorb the adhesive. In this process, the adhesive coagulates as soon as possible until the conjunctiva is dry, which is the key to good gloss of the finished product.
所以如果要提高印刷光泽度可以从以上几个方面入手尝试,当然也要注意有没有问题的存在,做好预防工作很重要。更多信息就来网站www.xinfengyinshua.cn看看吧。
