Influence of UV Varnish Pattern Effect on Print Quality
This article aims to define attributes of image quality that affect the quality of textured UV varnish applied as a pattern effect over offset prints. The most common UV varnishing problems that might influence attributes of print quality are reticulation of the varnish, poor adhesion, spreading of the varnish and shade changes. These problems mostly arise from inability to control the coating, especially if applied on differently generated print surfaces. Benefits of UV coatings in terms of image quality improvements might be greater opacity, color stability, deeper and more vibrant colors, sharper graphics, higher gloss and uniform surface to give labels a more vibrant look. Image quality variation assessment often needs to be carried out since an improvement made to one attribute can result in a deficiency to another attribute or attributes. In order to determine correlations between these attributes, a combination of objective and subjective image quality assessments has been applied.

The Journal of Imaging Science and Technology (JIST) is dedicated to the advancement of imaging science knowledge, the practical applications of such knowledge, and how imaging science relates to other fields of study. The pages of this journal are open to reports of new theoretical or experimental results, and to comprehensive reviews. Only original manuscripts that have not been previously published, nor currently submitted for publication elsewhere, should be submitted.
IS&T's JIST-first publication option allows authors wishing to present their work at conferences, but have a journal citation for their paper, to submit a paper to JIST that follows the same rigorous peer-review vetting and publication process as traditional JIST articles, but with the benefit of a condensed time-to-publication time frame and guaranteed conference presentation slot.
Please note: For purposes of its Digital Library content, IS&T defines Open Access as papers that will be downloadable in their entirety for free in perpetuity. Copyright restrictions on papers vary; see individual paper for details.
