UV印刷

UV印刷包装

UV胶印,分为彩色印刷和表面整饰两类。彩色印刷和传统常规印刷原理基本相同,表面整饰处理分为局部UV上光和全面UV上光。

全面和局部UV上光

局部UV:对印刷品表面特定区域的文字,图形(通常为客户的LOGO)UV上光,以达到强调突出的目的。

全面UV:对整个印刷品表面进行UV上光。

全面UV上光后,印刷品表面的光泽度可以和覆亮膜相媲美,并且在视觉效果上超越亮膜处理,可以用来替代亮膜处理。尤其当印刷品,包装品表面局部需要手写,或者盖章,而且客户对表面光泽度具有较高要求的时候,局部UV是唯一的选择。

2014年末的时候,我们为一个法国客户做一批挂历,客户希望挂历的封面既具有亮膜处理的高光效果,同时又能在右下角的地方写字盖章,我们就是通过大幅面局部UV的方式来满足客户的要求,客户收到样品后非常喜欢,很快就下单了。

传统胶印与UV印刷的区别

UV印刷与传统的胶印技术有着很大的区别,尤其在油墨的干燥方面。UV胶印油墨在高能量紫外光照射下迅速固化,油墨干燥所需的时间不到一秒,然而传统的单张纸胶印油墨需要几个小时才能完全干燥。

对于传统的胶印技术,印刷油墨的干燥途径主要有三种,挥发,渗透吸收,氧化聚合。

  • 挥发干燥:印刷油墨中的溶剂挥发到空气中,颜料固着到纸材表面。相对于UV印刷,UV油墨的快速干燥大大减少了有害气体的挥发,更加符合环保标准。
  • 渗透吸收:印刷油墨中的溶剂渗透吸收到到承印的纸材当中,油墨的粘度提高,颜料固着到纸张或纸板表面。塑料膜或胶片,金银卡纸由于没有渗透吸收性能,油墨无法有效快速干燥,传统的胶印工艺无法适用于这些承印物。同时,未经涂布纸板表面有着过多过大的微细毛孔,对油墨中的溶剂具有超强的吸收能力,这也导致印刷色彩不能很好地呈现。然而,UV印刷独特的光学干燥机制使其承印范围大大增加,即使在塑料膜,胶片,金银卡纸,未经涂布的纸材上面也能获得极佳的印刷效果。
  • 氧化聚合:印刷油墨中的调墨油氧化聚合,油墨粘度提高,颜料固着干燥。

UV印刷的优点

相对传统的胶印工艺,UV印刷有以下优点:

  • 1. 超级的光泽度,出色的高光,或者哑光效果,色彩饱满,光泽艳丽。
  • 2. 超级的耐磨性,有效保护印刷表面油墨色彩,防止刮痕。
  • 3. 愉悦的手感。
  • 4. 环保,不含溶剂,不产生挥发有害气体,减少空气污染。
  • 5. 不需要喷粉,减少印刷故障,保护环境。
  • 6. 适应于各种承印物,即使在透明塑料膜,胶片,未涂布的纸张,卡纸,PET金银卡纸上面也可以获得优质的印刷效果。
  • 7. 油墨干燥固化迅速,缩短生产周期,提高生产效率

UV印刷存在的问题:

1. 印刷成本高:设备价格高;UV油墨是普通油墨价格的4到5倍;UV印刷操作工人工资高

2. 专用的配套装置:印刷机必须配备专用的胶辊,印版,橡胶布,清洗剂和UV油墨固化干燥装置。

3. 技术含量高,工艺复杂难点多:首先,水墨平衡不易把控,容易造成严重的油墨乳化,脏版;其次,油墨固化程度不易掌握;第三,对色序要求程度高,安排不当会影响色彩饱和度。

UV印刷在包装领域中的应用

紫外线能量干燥油墨不含致癌物质,不会引起系统毒性,食品包装是UV印刷的最大应用领域。UV印刷广泛应用于折叠纸盒,冰激凌盒,CD/DVD标签和屋型盒。

A Glossy T-shirt Packaging and Mailing Box

A T-shirt Packaging Box With The Clean And Neat Feel

Traditionally, the telscope box style is very popular among the T-shirt and underwear packaging. The box has a top cover and a bottom base, which are seperate. And it is made of the SBS or CCNB paperboard with the very beautiful offset printing and finish. However, the box is easily crushed during the transit and distribution. When the products are in the hands of the consumer, they are wrinkled and damanged, looking very bad.
