Abstract

In the field of rotogravure, print quality requirements are particularly high. Increased brightness and whiteness in substrates, such as paper and paperboard, have increased the visual assessment of white area contamination, i.e. background discoloration in non-image areas. This has been increasing over recent years with no evident explanation. Publishers have made efforts to increase print quality by using whiter substrates, which has lead to a visual appearance of rotogravure background darkening (RGBD), in the in the most serious cases called toning.
