    不干膠標簽印刷對于UV油墨印刷應該注意什么?

    來源:http://www.apersianrug.com/ 日期:2021-05-06 發布人:admin 1、不干膠印刷設備的要求:其實有不少不干膠標簽印刷廠是通過在普通膠印機上加裝UV固化裝置來實現UV印刷,但這種設備改造方式存在著不少問題,如UV油墨腐蝕性強,可能會導致普通膠輥、橡皮布發生膨脹,影響印刷壓力的穩定性,嚴重時甚至還會導致膠輥出現脫皮或表面碎裂的現象。因此,UV油墨印刷對膠輥和橡皮布的要求極高,一般要求使用UV印刷專用的膠輥和橡皮布。
    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.
    普通叼紙牙在紫外光照射下,牙片部位會受熱發生變形,從而影響套印精度。因此,印刷單元上的叼紙牙一定要更換為UV印刷專用叼紙牙。

    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、腐蝕性強,不僅容易使普通墨斗片開裂破損,導致UV油墨流入墨牙傳動機構,使得墨牙驅動電機因阻力過大而出現故障,而且膠輥調整機構和串墨輥擺動機構也都容易被損壞。要求操作人員加強印刷設備的日常保養工作,清洗要徹底,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、對存儲條件的要求:上面提到的有關UV油墨固化問題、印刷穩定性等都需要一個重要的前提,那就是良好的油墨存儲條件。UV油墨存儲溫度更好控制在20~25℃,避免日光照射,相對濕度應控制在55%~65%,密封存儲,避免灰塵混入,且UV油墨存儲庫房內更好能夠保持恒溫恒濕。同時還應注意,UV油墨存儲庫房應遠離火源、熱源,以防發生意外事故。
    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.
