Abstract

Reflective prediction model is an important means to control printing quality and reduce energy consumption. In order to improve the printing quality control technology and reduce the energy consumption of pre-press proofing, a new spectral reflectance model that can predict the dot printing quality is studied. The optical phenomenon of the light beam in the ink paper was analyzed. The optical parameters affecting the change of luminous flux were measured. The entire process of light propagation in the printed material was simulated. By comparing the simulated dot data with the optical microscope value, the effectiveness was evaluated. The experimental results show that the spectral reflectance of printing dot can be effectively obtained in the whole wavelength band from 400nm to 700nm of D65 light source. The method of simulating light beam propagation can meet the requirements of color printing quality control. This paper combines the optical properties of printing materials and computer simulation technology to study the spectral reflectance model of amplitude modulation dots. The spectral reflectance model can realize both quantitative and qualitative evaluation of color printing dots through one simulation, which broadens the quality prediction method and control technology.
