INFLUENCES OF PAPER’S SPECTRUM REFLECTANCE VALUES ON THE COLOR REPRODUCTION OF PRINTING QUALITY
Spectrum reflectance values of printing paper are the ratios of reflected light energy to incident light energy, which represents the integrated nature of the incident light’s selective absorption, light scattering, light transmittance, and the paper surface’s reflection, which can be used to describe the color of the paper. In this work the paper’s spectrum reflectance values are adopted as parameters to analyze the paper’s color’s impact on the print’s color reproduction under the same printing conditions. According to the process of absorption of light and the Nuremberg equation, conclusions are drawn that there is linear relationship between paper spectrum reflectance values and the printing spectrum reflectance values in single color printing, and there is nonlinear relationship in multiple color printing. In experiments, firstly an ink-jet printer is used to print color patches on several papers whose spectrum reflectance curves were different, and these patches’ spectrum reflectance values at wavelengths from 400 nm to 700 nm are measured. Then the data set of the color patches’ measured values are fit to curves in order to contrast with the calculated values. The experimental result is consistent with the derived equation. The research provides a foundation for standardization and digitization of the printing process.
