济南博猫棋牌中的紫外烫印如何解决呢?

来源:http://www.zhongguoyingyou.com   日期:2019-12-25

  虽然紫外光清漆特殊的高亮度效果已经得到了大多数印刷技术人员的认可,但在印刷后的加工过程中,紫外光清漆的性能还不能满足要求。目前紫外光清漆热烫印适应性不成熟,热烫印质量不稳定。主要原因是树脂和紫外光清漆的成分不适合烫印。这些问题需要济南博猫棋牌厂家来解决。

  Although the special high brightness effect of UV varnish has been recognized by most printing technicians, the performance of UV varnish can not meet the requirements in the process of post printing. At present, UV varnish hot stamping adaptability is not mature, hot stamping quality is not stable. The main reason is that the composition of resin and UV varnish is not suitable for hot stamping. These problems need to be solved by Jinan packaging and printing factory.
  下面简要分析一下开发和测试过程中紫外光油层密封的难点。
  The following is a brief analysis of the difficulties in the development and testing process of UV reservoir sealing.
  (1)为了形成高亮度的效果,紫外光清漆必须有一定的厚度,但漆层过厚不利于烫印。UV胶印涂料厚度一般大于9g/M。
  (1) In order to form the effect of high brightness, UV varnish must have a certain thickness, but too thick paint layer is not conducive to hot stamping. The thickness of UV offset coating is generally greater than 9g / m.

  (2)为了保证紫外光清漆的固化性能,需要在uv涂料中加入特殊的树脂和大量的添加剂,这将不可避免的影响uv涂料表面热冲压的影响。
  (2) In order to ensure the curing performance of UV varnish, special resin and a large number of additives need to be added to UV coating, which will inevitably affect the hot stamping of UV coating surface.
  (3)目前紫外光漆树脂组成与高温高压烫印箔的相容性不够好,无法控制紫外光漆的烫印。
  (3) At present, the compatibility between UV paint resin composition and high temperature and high pressure stamping foil is not good enough to control the stamping of UV paint.
  因此,在印刷包装中,在紫外光油表面烫印需要注意以下几点。
  Therefore, in the printing and packaging, we need to pay attention to the following points in the UV oil surface hot stamping.
  (4)当需要增加紫外线油的亮度时,不推荐增加光油层厚度的方法。通过调整涂布工艺参数(涂布辊线角、线数等)和印刷设备性能(印刷压力、印刷速度等),提高涂布层的平整度和亮度。
  (4) When it is necessary to increase the brightness of ultraviolet oil, it is not recommended to increase the thickness of light oil layer. By adjusting the coating process parameters (coating roll line angle, line number, etc.) and printing equipment performance (printing pressure, printing speed, etc.), improve the smoothness and brightness of the coating layer.
  (5)合理选择冲压材料,使橡胶层与紫外光清漆树脂具有良好的亲和力。
  (5) Reasonable selection of stamping materials can make rubber layer have good affinity with UV varnish resin.
  (6)准确调整热版温度和压力,因为过高的压力和温度会损害油墨的表面性能,使烫印更加困难。同时,冲压速度不宜太快。
  (6) Accurately adjust the hot plate temperature and pressure, because too high pressure and temperature will damage the surface performance of the ink, making hot stamping more difficult. At the same time, the stamping speed should not be too fast.
