Abstract—Print mottle is one of the most detrimental factors to general print quality, and to get high quality print, the most important thing is to resolve print mottle problem. The evaluation method for print mottle is proposed by means of discrete wavelet analysis, in which the index of print mottle is built on the base of the coefficient of variance of the wavelet-filtered digital image. Then, in our research, we have compared the three methods: the visual assessment method, the traditional method, and the wavelet-based method. They were applied on offset papers to check their performance. The linear correlation coefficient obtained between the visual ranking of the samples and the results with the traditional method is 0.6148. While, t...
