1. a method that forms printed medium, it comprises at least one side that applies (240) substrate (110) with the charged nano-milled calcium carbonate of anionic property, the charged nano-milled calcium carbonate of this anionic property has carried out mixing (220) with cationic conversion agent (280) described coating (120) has been converted into the charged coating of cationic, the primary particle diameter of wherein said nano-milled calcium carbonate is 10-20nm or lower, in high-shear mixer (270), described cationic conversion agent (220) is joined in described nano-milled calcium carbonate, this performance constraint the reunion in cation conversion process.
