How to distinguish the quality of uv lamps?

1. Conventional high temperature and low intensity UV lamps, conventional high
temperature and low intensity UV lamps use domestic light-emitting electrodes
with low purity impurities and are filled with low purity luminous substances.
The UV lamp can only be started with high current, and the production process is
relatively simple and backward, and the production cost is also low. The produced
uv lamp has low luminous intensity, high luminous current, and high luminous
temperature, which causes the printed matter to be deformed by heat and can
not be overprinted, and can not dry UV ink and varnish at high speed, This type of
uv lamp is generally used in slow screen printing production with low overprint
requirements, and is not suitable for high-speed offset printing production
with high overprint requirements.

2.Offset printing Offset printing is widely used as the mainstream printing process of
high-grade printing because of its fine technology and rich color. Offset printing has
strict requirements for the expansion and deformation of printing and for the adaptation
to high efficiency and high speed printing. The UV lamp for offset printing must reach
a photofixation temperature of no more than 50 ° C to prevent the expansion and
deformation of printing, and the photofixation speed must reach 8000 sheets/hour,
The imported offset low temperature and high speed uv lamp is a kind of high pressure
mercury lamp that uses high purity luminous electrode and is filled with high purity luminous
gas with accurate proportion. It is produced through high-end technology, with low working
current, low temperature and high intensity, which is more than 40% lower than that of
conventional UV lamp of the same specification, and the luminous intensity is more than
100% higher. The offset low temperature and high speed UV curing machine is equipped with
intelligent high-speed automatic paper receiving machine, which controls the UV curing
temperature of printed matter at 45 ° C, UV light fixation speed reaches more than 9000
sheets/hour, which meets the technological conditions of low temperature and high speed
for offset printing, and is widely used in large printing industries such as cigarette label
packaging printing, color printing packaging printing, etc.
3. Special printing: imported UV lamps are widely used for screen printing, lithography,
letterpress printing, self-adhesive trademarks, metal nameplates, KT plates, glass, ceramics,
electronic parts, single-sided circuit boards and other special effects such as crystal ice,
frosting, crystal gemstones, seven-color embossed oil.
4. Low temperature high intensity UV lamp, low temperature high intensity UV lamp is
a low current high intensity high pressure mercury lamp produced by high-end technology
manufacturing process using imported high-purity luminous electrode, filled with accurate
proportion of high-purity luminous substances, and used in combination with power supply
with corresponding matching parameters, which can emit 365nm low temperature high
intensity light suitable for UV ink curing and drying, The luminous intensity is more than
100% higher than the intensity parameter of the conventional high temperature and low
intensity UV lamp of the same power, so that the UV ink and UV varnish can be dried at high
speed. Moreover, due to the low luminous current, the heat of the lamp tube is reduced,
and the luminous temperature is more than 40% lower than that of the conventional UV lamp.
The low temperature and high intensity light drying effect can be achieved without water cooling.
