How does the color of printing mesh affect plate making? In this passage, we will introduce the color of printing mesh and how color influence printing quality.
The color of printing mesh can be white, yellow, amber, red and so on. (Among them, white and yellow are most commonly used in printing industry). The color of the mesh has a great influence on the quality of the plate. Colored printing mesh, such as yellow, red, and amber meshes, can prevent light from diffusing when printed, while the use of white mesh prints can cause noticeable diffusion. This is because the photosensitive material has a large absorption peak in the ultraviolet region.
Since the white mesh reflects white light when the light source is irradiated, it affects the photosensitive material. The irradiation light passes through the transparent part of the positive graphic film to reach the emulsion coating, and reflection, inflection-reflection, and diffuse reflection phenomenon occur when the irradiation light contacts the white mesh, and the floating phenomenon of the printing plate is vignetting. If a colored printing mesh is used, it will prevent this phenomenon because the colored mesh can absorb a part of the irradiation light, thereby reducing the reflection intensity of the irradiation light, and the colored mesh reflects the color light. This color light is inactive light, so it does not affect the sensing material, especially When a fine-line article is printed, it is quite important to choose the proper color mesh for it.
