Five common problems with uv ink.Is uv ink environmentally friendly?
The uv ink does not contain the VOC that is harmful to the human body,
but the uncured uv ink is not in direct contact with the human body.
Long time of direct contact with the uv ink may stimulate the skin and eyes
and even have a chemical allergy to the skin. Operators are required to receive
professional training. Front-line operators should wear protective gloves,
protective eyes, protective aprons and protective boots to avoid
direct contact of uv ink with the body.
What is the difference between uv ink and eco solvent ink? The uv ink with
eco solvent ink are two different printing consumables. The uv ink can be
sprayed directly on the surface of the material to form a coating. The eco solvent ink
needs to be wiped before printing the pattern. Even after the pattern is printed,
it also needs to be put to be baked in the oven at high temperature
and the waste rate is high.
How long is the shelf life of the uv-printed images outdoors? Generally speaking,
it can be guaranteed for 5-8 years (without film coating, light oil and other
post-processing process)). The shelf life of the image has a lot to do with
the outdoor environment. If the outdoor environment is very bad, such as frequent
sun exposure, rain, strong wind, and other factors, the shelf life may lead to
less than 2 years. And indoor uv printer image shelf life is at least ten years above.
Of course, the quality of uv ink will also affect the shelf life of the outdoor.
The storage time of expensive imported uv ink is longer than that of domestic uv ink.
How about uv ink? The uv ink should be placed in a cool and ventilated place indoors,
placed on the shelf, and can not be placed in the place, which is easy to cause
the solidification of the internal ink precipitation. At the same time, it can not be pressed
above things, nearby can not put open fire, flammable items.
Can the uv ink be changed at will? No, blindly replace the uv ink, not only is to reduce
the quality of the print pattern, but also will shorten the life of the nozzle, serious words,
will directly cause the blockage of the nozzle scrapped. The harm to the whole ink
road system is also very great.
