Abstract
In order to promote the greening of flexographic printing and reduce the waste of consumables such as plates and printing materials. It is necessary to accurately predict the spectral reflectance of flexographic film-type printing and establish a spectral reflectance color prediction model for flexographic film prints. The prediction model of flexographic film prints is based on the theory of multiple internal reflections of photons in a plastic film substrate and horizontal transmission inside the plastic substrate, assume that the film and the ink have the same refractive index and the flexographic print is placed on a standard white background. Finally, we tested our model on a flexographic printing machine. Good agreement was found between the predicted and measured reflectance for the flexographic printed patches. The model could be used in prepress color prediction and virtual color proofing, significantly reduce printing materials and energy consumption.
