But because grenadine itself can stop advancing of light, and traditional exposure machine only exposes for a side of half tone conventionally, therefore, easily causes the shady face under-exposure of half tone, and the emulsion of half tone shady face cannot be hardened completely.In the time of developing process, unhardened emulsion can be washed out by water, and then affects the structure of half tone.Above-mentioned situation is more obvious in the half tone that uses metal grenadine.For reducing the generation of said circumstances, in industry, be by the time lengthening of half tone exposure in the past, increase the exposure effect of half tone shady face emulsion.But the prolongation of time for exposure also can cause the temperature rise of working space, cause egative film to shrink and affect the precision of screen painting.For these reasons, existing half tone easily occurs that emulsion fails the defect of complete coated grenadine, and causes the situation that the half tone number of resistance to impression declines thereafter.
Utility model content
For the foregoing reasons, the purpose of this utility model is to provide a kind of improvement screen structure, and the mode that it sees through multiexposure, multiple exposure, makes emulsion can be coated grenadine, the durability of promoting by this half tone completely.
For reaching aforementioned object, the utility model provides a kind of improvement screen structure, comprising: a grenadine layer, one first emulsion layer and one second emulsion layer.Described grenadine layer is to be formed by many warps and many parallel weavings.The some of described the first emulsion layer Wrapping net layer, and on the first emulsion layer, be formed with multiple the first openings.A part for described the second emulsion layer Wrapping net layer, and with the common complete coated grenadine layer of the first emulsion layer.On the second emulsion layer, be formed with multiple the second openings, and these second openings are corresponding to described the first opening.
According to an embodiment of the present utility model, a side of this first emulsion layer and a side of this second emulsion layer fit tightly mutually.
According to an embodiment of the present utility model, between the first emulsion layer and the second emulsion layer, further comprise at least one the 3rd emulsion layer.Described at least one the 3rd emulsion layer fits tightly with the first emulsion layer and the second emulsion layer respectively, and with the common complete coated grenadine layer of the first emulsion layer and the second emulsion layer.Wherein, be formed with multiple the 3rd openings on the 3rd emulsion layer, described the 3rd opening is corresponding to described the first opening and described the second opening.
