What kind of light source in the screen printing plate making, ideal?
Uv light lamp is an ideal light source, if there is a strong ultraviolet cold light lamp, the effect is much better.Domestic is mainly composed of 20 w/A, 30 w/A, 40 w/A, 80 w/A, 80 w/five, followed by high pressure mercury lamp, high pressure office lamp, high-pressure mercury lamp is no ordinary small sun, is the plate making special lights.
Plate with the two kinds of lights, pay attention to the temperature on the surface of the glass in high temperature season, should add fan cooled when necessary, to prevent overheating and emulsion crosslinking.
And cannot start in a row, both light is turned off, at least 5 minutes to restart.
Cold light lamp with uv light exposure, plate burning time is how long?High pressure mercury lamp and high pressure picks the lamp?
Ultraviolet ray of cold light lamp plate burning time control between 3 to 6 minutes (1000 w - mercury lamp or dysprosium lamp), sub thick, long, thin rubber, time is short, slightly longer in winter, summer is a bit shorter, for high pressure mercury lamp and high pressure dysprosium lamp, power grid voltage is high, the light is strong, plate burning time can be shorter, or longer.The specific time can be calculated through the right
What is the advantage of exterior cold light lamp?
Ultraviolet luminescence light, electronic rectifier, the light intensity is not affected by power grid voltage levels, 130 volts will start.It emits light range, the range of sensitive material needs.The lamp can run continuously, continuous, and low calorific value, one-time less investment.Is the most ideal light source screen printing plate making.
Several main plate burning lamp light.
Uv light lamp.The distance between the tubes and glass general control between 7 to 10 cm, high pressure mercury lamp and high pressure dysprosium lamp general lamp and the distance between the glass must be controlled between 50-70 cm.Lamp is apart from the design of the height, to consider the lights from a relationship with the light intensity, second, we must consider light distance and the uniformity of light, third, we need to consider the lamp calorific value.
Why can't print with fluorescent lamp?
Common fluorescent lamp, it is not the most ideal light source, because between the 3800 a - 4300 - a light is very weak, only about 1/20 of the and so on ultraviolet light, plate burning time is long, light crosslinking effect is poor, low voltage power grid and the light intensity is weaker, can only make a small number of photosensitive glue produces chemical reaction, revealed the film will automatically fall off, can also cause a lot of transparent rubber, printing ink when most or local printing, and resistance to low frequency, serrate.
