Can uv printer realize coating free?The coating free uv printer means that when

printing some materials, printing can be started without prepress treatment on

the material surface. It does not mean that all materials can be printed without coating.

The plastic material surface can be free of coating, commonly including mobile phone

shell and notebook shell; Gypsum ceiling is common in building materials. Some cannot

be printed without coating, such as glass, glazed ceramic tile, metal and other materials

with high surface density and smoothness cannot be printed directly.

Can uv printer realize coating free?The coating free is actually determined by the ink.

uv ink itself contains corrosivity, which can slightly (invisible to the naked eye) corrode

the material surface. In this process, the pigment components in the ink can be attached to

the material surface. Now there are also some uv inks that are free of coating on the glass.

In fact, the chemical agent is added. It seems that there is one less process, but the loss is greater.

The purity of the ink is reduced, and the impurities are increased, resulting in the nozzle being

blocked and scrapped in a very short time. 90% of materials such as glass, ceramic tile, metal,

leather, etc. printed by a weak solvent flat printer must be coated, because printing patterns directly

with weak solvent ink is likely to lead to ink piling, slow drying, poor printing and painting effect, etc.
