Abstract
A method for forming a printable coating includes providing a calcium carbonate, combining a dispersant with the calcium carbonate, nanomilling the calcium carbonate and the dispersant to inhibit re-floccing of the nanomilled calcium carbonate, and combining the mixture with a binder at alkaline pH. According to one exemplary embodiment, the coating may be applied to one or more sides of a media substrate.
