Description
Two-step high-speed Vacuum System Two-step high-speed vacuum-exhausting system of contact exposure frame can make vacuum-exhausting operate from the center and spread all round, thus ensuring a 70% higher speed than average exposure frame. (Plate of any material is ready to expose within one minute Excellent Light Source (Ushio or Philip) High quality reflection board with strong reflecting light, which is verified to be more than 86% uniformity. Good-quality violet light source, whose wavelength is 365-420NM, is three times the light intensity as average ones. High exposing quality and long time duration. Anti-electrostatic rubber cloth and block gine with strong air-tightness and durability. Secondary Exposure System Secondary exposure system can wipe out dirty spots and imprints of the block gine efficiently, thus reducing retouch work and raise the efficiency of work. Oil Less Vacuum Pump Best quality oil less vacuum pump runs noiselessly and lasts without maintenance. Precision Integrating Light Meter Accurate integrating light meter automatically detects the light intensity of the light source, so as to accurately keep the error range within 2% and eliminate the distortion of screen dots caused by the deterioration of lamps, instability of voltage, etc. Easy Operation and Long Operation Life The screen can display 5 sets of data. The CPU can store 99 sets of data. Enhanced steel frame processed by numerical control and thick film coating of electrostatic powder for ultra-long operation life. External joint factory inspection on the 0-100 step printing down to ensure 2% of halftone dots aren't lost and 98% are not mixed.
