Study on the Assessment Method of Print Mottle Using Discrete Wavelet Analysis

摘要：

　　Aiming at one of most common problems of print quality,print mottle,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 ofdenosing digital image.Then,it was applied on offset paper to check its performance.The analytical results compared with visual perception shows that the assessment method proposed is effective and practical in measuring printing mottle.The correlations with visual evaluation are over 0.76.
