Research on Fuzzy Evaluation of Ink-Jet Paper Printability
Based on the experiment, this paper used principal component analysis and multiple regression analysis to establish a fuzzy evaluation system between the paper performance and print qualities. Five kinds of ink-jet paper with different surface characteristics were chosen in this paper to test their properties including absorbability, gloss, roughness, whiteness etc. During the same printing condition, using the digital proofer of EPSON Stylus Pro7880c, the standard wedge of GATF, solid color lumps and standard lines were printed on these paper samples; dot gain and solid densities were tested by SpectroEye, then contrast-K was calculated, the qualities of lines were analyzed with QEA image Analysis. Finally, paper surface characteristics were analyzed with principal components analysis, and definition of printing was analyzed by QEA Image Analysis, correlation between paper basic performance and the characteristics of printing qualities, such as dot gain, solid density, definition and contrast-K, and an integral evaluation function and a model were established. When evaluating on paper, as long as its surface characteristics were tested, the printability of different paper can be evaluated in a fuzzy and integral way through the calculation of the model and evaluation function. This work offers a certain theoretical reference and practical guidance to the selection of ink-jet paper and the improvement of ink-jet qualities.
