The aim of this work is to clarify the controlling role of polyvinyl alcohol (PVOH) as a binder in the formation of coating and pore structure and how it affects the high-speed inkjet image quality formation. The results show that the pigment type and the binder amount have a large interactive effect on pore structure formation. The optical properties of the whole paper, not just the coating, are the most important regarding print density, but the properties of the coating layer itself have a dominant effect when considering the ink bleeding.
