Since uv ink is uv curable ink, and the sun contains uv, what are the requirements of
uv ink on the environment of the printing workshop? Therefore, it is recommended
that the indoor sunlight in the uv ink printing workshop should not be too bright.
If the workshop is too bright, you may as well install curtains to block the light. If there
are many fluorescent lamps in the printing workshop, please pay attention to the uv
transmission phenomenon caused by the falling of silver powder on the fluorescent lamp
surface. Both the indoor light and the uv transmission phenomenon of the fluorescent
lamp will cause the uv ink to solidify on the screen during the printing process,
thus blocking the screen. In the production line where the sunlight is too bright,
please pay special attention to the production line near the window, and take back
the uv ink on the screen in time after printing to avoid curing.
Control the temperature and humidity in the car room. What are the requirements of
uv ink on the environment of the printing workshop? If the temperature is low and
the humidity is high, the uv curing reaction of the uv ink is slow, and the combination
ability of the ink and the substrate is reduced. Therefore, the ambient temperature and
humidity of the workshop must be well controlled during uv printing. The general
temperature is about 18 ℃~25 ℃, and the relative humidity is about 50%~65%. Moreover,
the spectral ranges of ultraviolet light are different. Good lamps have small spectral ranges
and high ultraviolet purity. The spectral range of low-quality lamps is generally wide in
specific efficiency, the ultraviolet rays are not concentrated, showing a diffusion image,
and the purity is low, so the curing effect is poor. The use time of a lamp tube is about
1000 hours. The adhesion is greatly affected by improper operation of uv equipment.
