Abstract: A coating composition for a corrugated paper board is described. The corrugated paper board includes an inner liner sheet and an outer liner sheet adhered to opposite sides of a corrugated medium. The coating composition includes a pre-coat layer and a topcoat layer. The pre-coat layer includes an ink fixer agent and a pigment, and is disposed on one or both of the liner sheets. The topcoat layer is disposed on top of the pre-coat layer to form an ink receiving layer. The topcoat layer includes a wax and is devoid of the ink fixer agent.

Abstract: An example of a printable recording medium includes a base substrate and an ink-receiving layer. The ink-receiving layer includes an inorganic pigment in an amount equal to or greater than 70 wt % and an ink-fixing agent in an amount ranging from about 3 wt % to about 10 wt % based on the total wt % of the ink-receiving layer. The inorganic pigment has a median particle size ranging from about 0.5 μm to about 5 μm. The ink-receiving layer excludes precipitated calcium carbonate.

Abstract: An example of a pre-treatment fixing fluid for an offset coated medium includes calcium propionate, calcium pantothenate, tetraethylene glycol, a surfactant having an HLB less than 10, an acid, and a balance of water. The calcium propionate is present in an amount ranging from greater than 4.5 wt % to 8.0 wt %, the calcium pantothenate is present in an amount ranging from about 2.0 wt % to equal to or less than 15 wt %, and the surfactant is present in an amount ranging from about 0.01 wt % to about 1.0 wt %, each based on the total wt % of the pre-treatment fixing fluid. The acid is present in an amount sufficient to render the pH from about 4.0 to about 7.0.
