  为了保护不干胶标签的印刷图案,提高标签的质量,目前不干胶标签印刷后很多都选择了覆膜、上光、烫金等表面处理。
  In order to protect the printing pattern of adhesive labels and improve the quality of labels, many of them choose coating, polishing, bronzing and other surface treatments after printing.

  上光技术主要应用于镜面涂布纸、涂布纸类标签的表面涂布,其目的是增加其表面光泽度,并达到防污、防潮、保护图案。按加工方法,标签材料上光分为单张纸上光和卷筒纸上光,其中卷筒纸是标签印刷工艺中较常用的方法。
  The polishing technology is mainly applied to the surface coating of mirror coated paper and coated paper labels. Its purpose is to increase the gloss of the surface, and to achieve anti-fouling, moisture-proof and protection patterns. According to the processing method, label material polishing can be divided into sheet paper polishing and web paper polishing, among which web paper is the most commonly used method in label printing process.

  二、UV上光工艺应注意以下事项:
  2. The following points should be paid attention to in UV polishing process:
  1、对油品质量进行验证
  1. Verification of Oil Quality
  UV上光,有一定的存储周期,和环境有一定的要求,所以使用前四川应该检查玻璃的颜色和量化涂层干燥后,和添加剂的匹配,还注意观察与油墨是否有反应。一般要求先进行上光试验,然后投入正常生产。

  UV polishing has a certain storage period and certain environmental requirements, so before use, Sichuan should check the color of glass and quantitative coating after drying, and the matching of additives, and pay attention to whether there is reaction with the ink. Generally, it is required that the polishing test be carried out first and then put into normal production.
  2、关于油的厚度
  2. On the Thickness of Oil
  UV清漆性能不如溶剂型清漆好,如果涂布量过大会使表面出现浅色条纹,影响光的反射效果。涂布量过大会使上油干燥不彻底,只会使表面干燥,造成复卷后粘连。
  The performance of UV varnish is not as good as that of solvent varnish. If the amount of varnish is too large, light stripes will appear on the surface, which will affect the reflection effect of light. Excessive coating will not dry the oil thoroughly, but will only dry the surface and cause adhesion after rewinding.
  3、关于油的粘度和表面张力
  3. On Oil Viscosity and Surface Tension
  其粘度对其流平特性、干燥速度、表面光泽度都有影响。根据不同的纸张,调整适当的粘度。在控制粘度的同时,还要注意油的表面张力的变化。使清漆的表面张力小于油墨层的表面张力,这样,清漆就能完全湿润表面,避免出现针孔、条纹等质量问题。
  Its viscosity has an effect on its leveling characteristics, drying speed and surface glossiness. Adjust proper viscosity according to different paper. In addition to controlling the viscosity, we should pay attention to the change of oil surface tension. Make the surface tension of varnish less than that of ink layer, so that the varnish can completely wet the surface and avoid pinholes, stripes and other quality problems.
  4、速度、涂膜量、压力、干燥温度
  4. Speed, Film Volume, Pressure and Drying Temperature
  上光涂布速度、涂布量、压力和干燥温度四种因素相互制约,根据纸张表面的不同对其润湿、吸收、合理调节三者之间的关系。
  The four factors of polishing speed, amount of coating, pressure and drying temperature are mutually restrictive. According to the different surface of paper, the relationship among wetting, absorption and reasonable adjustment is discussed.
  5. 定期检查紫外线干燥设备
  5. Regular inspection of ultraviolet drying equipment
  UV灯在UV干燥装置中随着使用时间的延长,有效功率逐渐降低,一般UV灯的有效时间为1000小时。生产中应定期检测有效功率,当使用时间接近1000小时时更换有效功率。
  The effective power of the UV lamp in the UV drying device decreases gradually with the prolongation of the use time. The effective time of the general UV lamp is 1000 hours. Effective power should be periodically tested in production and replaced when used indirectly for nearly 1000 hours.
