According to the printing surface gloss level, the varnishing is divided into 3 types, glossy varnishing, matte varnishing and satin varnishing.
With the glossy varnish, the printed box surface is smooth, shiny and glossy. In the sunshine, the surface reflects light quite efficiently. Therefore, a glossy varnished printed box usually has the very bright and lustrous color.
A matte varnish gives the printed box a non-glossy, smooth even surface free from shine. This matte finish on the printed box adds to the feeling of luxury. It is the most popular finish used in the cosmetic packaging boxes and jewelry packaging boxes when the seller wants to impart a luxury quality feel to the potential customers.

A satin varnish gives the printed box surface a neither high gloss or matt, but the middle ground look.
Also called UV coating, UV varnishing is a process for achieving a thicker and even more striking type of coating on the printed box surface. The printed color appears noticeably richer and vibrant. It also adds the benefit of the fast drying of print on the production line due to the ultra-violet drying process.
The UV varnishing divided into 2 types, all-over UV varnishing and spot UV varnishing
With the all-over UV varnishing, the UV inks are applied all over the printing surface. The high gloss level can rival and replace the glossy laminating. In the meantime, it provides the excellent protective qualities and a pleasant tactile experience to the printing surface.
With the spot UV varnishing, the UV inks are only applied to the specific area of the printing surface to highlight specific texts or images, particularly the logo. The Spot UV varnishing on the brand logo is widely used for the luxury paper bags, boxes, gift boxes, cosmetic packaging boxes, jewelry boxes, and some retail packaging boxes.

There are 3 common types of protective coating for the printed packaging boxes, varnishing, aqueous coating, and UV coating.
Varnishes were first introduced to the printed packaging industry as they are essentially transparent inks without a pigment. They are applied as the common CMYK inks during the printing process. The finish can be glossy, matte and satin. The varnishing is typically the least expensive of all the coating options available.
Most varnishes are VOC based, which is not eco-friendly. Another drawback of the varnishing finish is that the varnish takes a long time to dry on the printing surface.
Aqueous Coating were developed in the late 1970s, which is also referred to as AQ coating.. Aqueous is water-based with the water content at the percentage of 30-40%. It is an environmental friendly coating, because it doesn’t cause the VOC emissions as varnish does.
The AQ coating is dried by the infrared radiation. The advantage is that it reduces the need for powder on the printing press. It is also yellowing-resistant, which is quite common with the varnished boxes that are stored for a while. Ghosting problems also tend to be removed and it complies with environmental laws.
Normally, aqueous is usually applied to the entire sheet as opposed to spot coating (spot UV). On the down side, aqueous often costs twice as much as varnish. And it takes more time to dry than the UV coating.
UV Coating is by far the most popular coating options for the folding paper box, because it has the highest gloss and is rub-resistant. It starts as a clear liquid that is cured (dried) instantly with an ultraviolet light radiation. It comes in a wide range of sheens. The most common usage is the Spot UV varnishing, which is applied partially to highlight the brand logo of the company.
There are 3 purposes of the coating|varnishing finish on the surface of the printed paper box.
