What is the difference between UV and oiled?

1. What does over-oiling mean?

Generally speaking, over-oil refers to the meaning of over

varnish.The purpose is to increase the gloss of the surface of the product, increase the effect of reflection, and make the product look much higher; it can protect the ink on the surface and prevent the ink on the surface from being easily wiped off. On the surface of the printed matter, a layer of varnish or matte oil, waterproof, scratchresistant, etc., at the same time, the varnish can improve the brightness of the printed matter, and the matt oil can make the printed matter more high-grade. At the same time, oiling has no three-dimensional effect, unlike UV, so the cost of oiling is low. Basically, the packaging needs to be oiled to protect the product;

2. What does UV mean? UV is varnish.

It is made of a special coating for UV that is precisely and uniformly applied to the performance or local area of the printed matter, and then irradiated by ultraviolet rays, dried and hardened at a very fast speed. It is used for packaging, covers, etc., also known as polishing bright.

The surface of the material after UV varnishing is bright, but it is relatively brittle and prone to cracks! The quality of the varnish is very good, which is comparable to lamination. To increase the three-dimensional effect, at the same time, the hardness is high, and it is resistant to abrasion and scratches; for general export commodities, filming is not allowed, and UV varnishing oil is a very suitable treatment method.

The two have different concepts. UV oil refers to UV curing overcoat varnish, which is characterized by: it must be cured by UV lamp, fast curing speed, wearresistant, relatively environmentally friendly, low surface energy after curing, not easy to bond. Over varnish is to increase the gloss of the product surface and increase the effect of reflection

Extended Knowledge Local UV:

Partial UV refers to local glazing coating on the prominent parts of trademarks and packaging prints according to the needs of product glazing. Compared with the surrounding patterns, the glazing pattern is bright, bright, and has a strong three-dimensional effect, which can produce a unique artistic effect. .

Common local UV effects are: local brightening, local matting, local frosting, local colorful local refraction, local wrinkles and local ice flowers, etc. While highlighting the theme of the layout, it also improves the surface decoration effect of the printed product. Partial UV is mainly used in the post-press finishing of book covers and packaging products, in order to achieve the purpose of making printed products icing on the cake.
