Application of the Gray Relevancy Method in Synthetic Evaluation of Inkjet Paper's Printing Quality

Based on the gray relevancy method,the printing quality of glossy inkjet papers is evaluated by subjective and objective(color density,tone reproduction,gamut,color difference,line,dot,etc) evaluations.The correlation degree of glossy inkjet printing paper is calculated by using a multilevel grey evaluation model.The higher the correlation degree is,the better glossy inkjet printing paper's comprehensive printing quality is.
