A method of producing inkjet media (170) includes dissolving heptahydrate epsomite in a coating solution comprising at least one surface sizing additive, coating at least one side of a substrate with the coating solution to produce the inkjet media (170). An inkjet medium (170) includes a substrate (172) and a coating layer (174) comprising heptahydrate epsomite deposited on a first side of the substrate, the coating layer (174) having a substantially uniform distribution of heptahydrate epsomite throughout its volume.
