不干胶标签印刷对于UV油墨印刷应该注意什么?

来源:http://www.shengfengyinshua.com/ 日期:2021-05-06 发布人:admin 1、不干胶印刷设备的要求:其实有不少不干胶标签印刷厂是通过在普通胶印机上加装UV固化装置来实现UV印刷,但这种设备改造方式存在着不少问题,如UV油墨腐蚀性强,可能会导致普通胶辊、橡皮布发生膨胀,影响印刷压力的稳定性,严重时甚至还会导致胶辊出现脱皮或表面碎裂的现象。因此,UV油墨印刷对胶辊和橡皮布的要求极高,一般要求使用UV印刷专用的胶辊和橡皮布。
1. Requirements for self-adhesive printing equipment: in fact, many self-adhesive label printing plants realize UV printing by installing UV curing devices on ordinary offset presses. However, there are many problems in this equipment transformation, such as strong corrosion of UV ink, which may cause expansion of ordinary cots and rubber cloth, affecting the stability of printing pressure, In serious cases, it can even lead to peeling or surface fragmentation of cots. Therefore, UV ink printing on cots and blanket very high requirements, generally require the use of UV printing cots and blanket.
普通叼纸牙在紫外光照射下,牙片部位会受热发生变形,从而影响套印精度。因此,印刷单元上的叼纸牙一定要更换为UV印刷专用叼纸牙。

Under the ultraviolet light, the teeth will be heated and deformed, which will affect the overprint accuracy. Therefore, the paper holding teeth on the printing unit must be replaced with those for UV printing.
要知道UV油墨黏度高、腐蚀性强,不仅容易使普通墨斗片开裂破损,导致UV油墨流入墨牙传动机构,使得墨牙驱动电机因阻力过大而出现故障,而且胶辊调整机构和串墨辊摆动机构也都容易被损坏。要求操作人员加强印刷设备的日常保养工作,清洗要彻底,并使用合格的配件和原料耗材。
It is necessary to know that UV ink with high viscosity and strong corrosiveness is not only easy to crack and damage the ordinary ink bucket, but also cause UV ink to flow into the ink teeth drive mechanism, which makes the ink teeth drive motor fail due to excessive resistance, and the rubber roller adjustment mechanism and the string ink roller swing mechanism are also easy to be damaged. Operators are required to strengthen the daily maintenance of printing equipment, clean thoroughly, and use qualified accessories and raw materials.
2、对存储条件的要求:上面提到的有关UV油墨固化问题、印刷稳定性等都需要一个重要的前提,那就是良好的油墨存储条件。UV油墨存储温度更好控制在20~25℃,避免日光照射,相对湿度应控制在55%~65%,密封存储,避免灰尘混入,且UV油墨存储库房内更好能够保持恒温恒湿。同时还应注意,UV油墨存储库房应远离火源、热源,以防发生意外事故。
2. Requirements for storage conditions: the above-mentioned problems about UV ink curing and printing stability need an important premise, that is, good ink storage conditions. The best storage temperature of UV ink should be controlled at 20 ~ 25 ℃ to avoid sunlight, the best relative humidity should be controlled at 55% ~ 65%, sealed storage to avoid dust mixing, and the UV ink storage warehouse should be able to maintain constant temperature and humidity. At the same time, it should be noted that UV ink storage warehouse should be far away from fire and heat sources to prevent accidents.
