Can is divided into kinds of solid photosensitive resin version and liquid photosensitive resin version. There is some differences between the and the different types of material, the production process is different, the Performan Ce is different, and the application is the same.
L) Liquid photosensitive resin plate.
Plate in a specific exposure device on pre coated photosensitive resin. Exposure device by Upper and lower, pieces of precision on the glass plate and the upper and lower ultraviolet Urce, so, a printing plate are made and the back of the exposure.
The coating liquid resin, the main exposure and back exposure.
Facing the spreading the liquid resin. The negative image of the emulsion, and is placed in a glass, and covered with a layer of thin films, plays a protective r OLE in the vacuum pumping the film and Yin pictures close contact (in the covering film are coated with a light-sensitive R Esin liquid, the resin layer above placed on the base plate. Put the glass down, so, the photosensitive resin layer is sandwiched between and the pieces glass. Back exposure of the base and resin bonded firmly; Main Exposure,printing company, the light through the Yin shot to the photosensitive resin layer, by the light curable res In as solid, the without light photosensitive resin are still liquid state. So, after the exposure of the plate, inclined to put in a recycling tank, the version of the non exposure of excess resin To is recycled.
The Flushing (Xian Ying).
have been exposed to liquid photosensitive resin plate, use special brush brush in the residue in the groove of the machine Layout. After washing the plate, put in the oven dry, and then after the exposure treatment, in order to make the printing plate O n the complete hardening of the resin.
Domestic FLEXO industry using liquid version is not much, only used in the corrugated plate. The problem of plate Co., low resolution format, poor hand, not suitable for the production of fine image printing.
2) solid photosensitive resin plate.
This is a pre-coated version, like the use of the PS version of the same lithographic printing. Usually should is stored in the box to avoid light. Use, according to the size of the plate, from the box to remove the cutting, very convenient.
Currently, the commonly used flexible solid photosensitive resin plate materials have DuPont Sally (Cyrel) version of the, BASF (BASF) version, the Chinese version of GS, the Poly sent Japanese edition, Prosperity version, and so on. These plates has a series of products, with different specifications, thickness and hardness, etc. They has COMMON:A. Plate structure is the same; B. Exposure machine, washing machine with the same; C. Wash version of the same solution is trichloroethylene, tetrachloroethylene, such as organic solvent; D. Operation in the same process to go through the same process.
Production Process SOLID Resin PLATE:
Manuscript, making positive Yin, opens the material cutting, pre exposure, exposure, washing (developing), drying, after t Reatment, after exposure to correction.
