The color of the screen printing mesh is yellow, white and the like. How to choose?
Many customers choose yellow screen. What we should know is that the dazzling color is due to the effect of light, and there is no color without light. The color of light is determined by the frequency of the light wave. Red, orange, yellow, green, blue, basket, and purple are the light that people can feel by the visual nerves, called visible light. The surface of the object selectively absorbs and reflects light to obtain different colors. In short, any color we can see is the color of light. That is, when a beam of light hits the surface of a yellow object, only the yellow light is reflected, stimulating our optic nerve and coloring, while other colors are absorbed, so we see that the color of the object is yellow.
When printing on a polyester screen printing web,
ultraviolet light is used. Purple light is a mixture of two colors of cyan and magenta in the color, which means that the yellow hue is missing in black. When exposed, the yellow color of the purple plus mesh is superimposed into black, so the surface of the yellow screen (ie, the bottom of the emulsion layer) is not sensitive or less exposed, so there is no "back drying" phenomenon, resulting in high image clarity. , will not produce vignette.
When light passes through the transparent portion of the film to reach the emulsion layer, reflection, refraction, and slow motion are generated on the surface of the white screen located at the center and bottom of the coating layer. Exposure from the bottom and inside of the coated surface. It causes a faint glow during exposure and affects the reproduction of the hue.
