Study on the Evaluation Method of Print Mottle Using Discrete Wavelet Analysis [PDF]
Advances in Engineering Research, 2015 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 ...

Automated Mottling Assessment of Colored Printed Areas [PDF]
, 2007 Mottling is one of the most significant defects in modern offset printing using coated papers. Mottling can be defined as undesired unevenness in perceived print density. Previous research in the field considered only gray scale prints. In our work, we extend current methodology to color prints.

A Study of Oriented Mottle in Halftone Print
, 2007 Coated solid bleached board belongs to the top-segment of paperboards. One important property of paperboard is the printability. In this diploma work a specific print defect, oriented mottle, has been studied in association with Iggesund Paperboard. The objectives of the work were to develop a method for analysis of the dark and light areas of oriented
