Screen with white, yellow, amber, red, etc.The color of the screen has a great influence in the quality of plate making.Colored silk screen ? for example ? yellow, red, amber, silk screen ? can prevent light plate burning phenomenon of diffuse ? with white silk screen print will appear obvious diffusion phenomenon.This is because the ? light-sensitive materials have larger in the ultraviolet absorption peak ? the white screen when illuminant reflection is white ? thus have an impact on light-sensitive materials.Irradiation light emulsion coating are reached by Yang figure film transparent parts ? irradiation light contact occurs with white silk screen reflection ? inflectional -- reflection ? ? diffuse phenomena appear plate floating phenomenon, namely the halation.If you use the colored silk screen will prevent this kind of phenomenon because of color screen can absorb part of the irradiation light, thus reducing radiation ? reflection intensity of light and color screen reflection of a light colored light ? this light is not active ? ? won't impact so sense to choose material especially the fine print when printing the color of the wire mesh is particularly important.
