The abbreviation of ultraviolet (UV) is a special ink treatment process in the printing industry, also known as UV glazing process. The part of the album cover that needs to be highlighted after local UV treatment can be more understood. For example, the logo part will have a convex feeling and special brightness after local UV treatment. The text and pictures after UV treatment, More texture, more three-dimensional, more artistic, playing the finishing touch effect. Take a look at the effect of local UV below.

按过UV的面积来分，分为：整版UV和局部UV。

According to the area of UV, it is divided into: full version UV and local UV.

局部uv刚才已经举了一个例子了，而整版uv效果一般不是很明显的，从表面上看类似于过光油，但比过光油更加显亮，但对印刷品表面并不起保护作用，而过光油却对能印刷品的表面起一定的保护作用，比如防止刮花。用鼻子闻一闻，味道比较难闻，有一股塑胶的糊味。

Local UV has just given an example, but the full page UV effect is generally not very obvious. On the surface, it is similar to varnish, but it is brighter than varnish, but it does not protect the surface of printed matter, while varnish can protect the surface of printed matter, such as preventing scratches. Smell it with your nose. It smells bad. It smells like plastic paste.

UV油墨也分好多种，这些油墨往往有特殊的光泽和肌理，有镜面油墨、磨砂油墨、发泡油墨、皱纹油墨、锤纹油墨、彩砂油墨、雪花油墨、冰花油墨、珠光油墨、水晶油墨、镭射油墨等等。我们常见的就是镜面UV，从字面的意思上能看出，对印刷品某个部位局部UV后，表面像一面镜子，用手摸上去很光滑，局部UV的地方和印刷品的其它部位相比感觉到有一个明显的界限，比较有立体感。

UV inks are also divided into many kinds. These inks often have special luster and texture, including mirror ink, frosted ink, foaming ink, wrinkle ink, hammer ink, colored sand ink, snowflake ink, ice flower ink, pearlescent ink, crystal ink, laser ink and so on. Mirror UV is common to us. It can be seen from the literal meaning that after local UV is applied to a certain part of the print, the surface looks like a mirror and feels very smooth by hand. Compared with other parts of the print, the local UV has an obvious boundary and a three-dimensional feeling.

过UV所采用的设备叫UV光固机，原理就是通过紫外光照射来固化UV油墨。局部UV既可在覆膜后实施，也可在印刷品上直接UV，但为了突出局部UV的效果。一般是在印刷品覆膜后进行，且以覆亚膜居多，约占局部UV产品的80%左右。过UV后的印刷品一般很难再回收利用。

The equipment used for UV curing is called UV curing machine. The principle is to cure UV ink through UV irradiation. Local UV can be implemented either after coating or directly on printed matter, but in order to highlight the effect of local UV. Generally, it is carried out after the printing is covered with film, and most of them are covered with sub film, accounting for about 80% of local UV products. After UV printing, it is generally difficult to recycle.
