How to deal with fading of uv printer coating printing?The uv printer is a device that

can be used by everything, whether it is the soft film in the advertising industry, the knife

cloth, or the wooden doors, floors, glass, tiles, etc. in the building materials industry,

it can be printed. However, the difference between them is that some materials can be printed

directly, and some materials can only be printed after coating, such as glass,

acrylic and other smooth materials. Sometimes there will be coating

discoloration, and what are the causes of coating discoloration.

How to deal with fading of uv printer coating printing? There are three main reasons

for coating fading:The problem with the coating itself: different materials use different coatings.

For example, the glass coating will not fade when it is used on glass, but it will fade when it is

placed on metal when it is printed with a uv printer. Therefore, the solution to this problem is

to confirm whether a special coating is used when printing materials.

Uv ink problem: This problem may occur if the uv ink used is not original. The color of the ink

surface looks the same, but the components of the curing agent and the blending agent inside

are different. Therefore, it is recommended to use the uv ink provided by the manufacturer.

Before leaving the factory, the uv machine will be debugged according to the customer's

requirements. This process includes ink matching test.

Coating treatment: some coatings can be directly printed after being directly wiped on the material

surface, but some coatings are not allowed. For example, after the common metal coating is wiped,

it needs to be placed in the oven for about 5 minutes to improve the adhesion.

Please confirm the application method of coating in actual printing.
