大家好，
刚接到一个客户的询价，在加工中提到了 satin varnish 和 matt varnish。我查了下，是上光，但这些分别是指那种上光呢？
我在网上找了一下相关的英文，大概的解释是
Varnishing: Through spraying or printing, applying a thin,transparent coating (called varnish) to printed work or book covers for gloss or protection purposes. Varnish can be classified into water-based and UV varnish according to its drying method. Depending on reflectiveness of coating, varnish can be further classified into glossy, matt, and satin types.
谢谢了！
