Influence of novel GCC particles on printing properties of high glossing coated wood-free papers, 2021 TAPPICon Live (21TAPL)

In order to evaluate the possibility of using less clay in top coatings and optimizing the printing properties of high glossing coated wood-free (CWF) papers, a novel class of ultrafine ground calcium carbonate (UFGCC) pigment particles, with a precisely optimized particle size distribution (PSD), has been developed. Coating colors containing this new class of UFGCC pigments allows the production of both smooth and glossy paper surfaces. In addition, higher brightness can be achieved while allowing to reduce the amount of optical brightening agents (OBAs) in the coating color. As an additional benefit, better control of the capillary structure can be attained as indicated in significantly improved porosity, which has an impact on, e.g. offset printing properties, in terms of tack, ink absorption and permeability. In conjunction with laboratory drawdown coating experiments, these effects and their implications were evaluated in a comprehensive pilot coating and an industrial scale printing trial, which demonstrated that brighter paper with high gloss, low yellowness and good printability can be achieved using this new class of UFGCC pigment particles in coating formulations.
