Producing LWC Rotogravure Paper on a Metered Size Press, 2000 Metered Size Press Forum

PressWeb.jpg

There is a major opportunity to reduce the cost of producing LWC papers by using on on-line system, consiting of a metered size press for coating and a modern multi-nip calender. The pigments used to produce rotogravure paper are known to have less than ideal rheology which makes their application difficult. It has been demonstrated that major differences in the degree of misting and paper quality can be observed for both the different pigments and binders. Higher machine speeds had the expected effect of increasing misting. Paper and print quality were related to the pigment characteristics. It was shown that the binder that induced the highest degree of thickening gave worse rotogravure printability in term of missing dots. With the optimum choice of pigments and formulation, it was possible to achieve reasonable paper and print quality comparable to blade coated paper at 1800 m/min with only a little misting.
