Effect of Paper’s Spectral Reflectance on the Printing’s Dot Gain
Paper is the main print material, whose performance is a factor that effects the printing’s dot gain which is bad to image clarity and color reproduction. In the paper, Yule-Nielsen neugebauer spectral modal is analyzed , and the relation between paper’s spectral reflectance and the printing’s dot gain is discussed. By experiments, the paper’s spectral reflectance is adopted as correction index, which can reduce the dot gain value of the light color patch , and in the same printing conditions the dot gain is effected by the paper’s spectral reflectance, ink’s type, dot area percentage and wavelengths. The research has a certain significance for controlling printing quality and reducing the producing cost.
