2.Excellent performance in developing.
3.Wide tolerance in operating condition.
4.Unique hydrophilic layer treament, good ink-water balance.
5.Excellent air education layer, good dot-reproduction.
Ratio:concentrate developing liquid: water=1:7~1:10
When the developing temperature is over 30℃, it will hurt plate oxidized layer, which will result in spoil of plate, affecting with dust and lower resolution and duration. You should stir adequately and make it according to the introduction manual when prepare the developer, the left developer should be stored with sealing to protect from useless.
Gas leading technology
This international advanced online gas leading technology reduces the time for plate making and effectively reduces the spoil of basking and simplifies the operation as well as enhance the quantity of pictures and characters, especially apply to the newspaper printing and high level color printing.
Enhanced the plate`s stability to be printed repeatedly produce best balance between water and ink in the process of printing.
Sensitive Colophony layer
This sensitives film boosts the characters of high speed, short transition period, high resolution ratio etc.
