Solvent-based pigmented ceramic inkjet ink compositions including a solvent blend consisting predominantly of one or more hydrophobic solvent(s) (preferably one or more hydrophobic long chain hydrocarbon solvent(s)) are capable of achieving superior print quality when applied over unfired glazes by the inclusion of less than 10% by weight of the composition of a water-soluble solvent, especially glycol ethers. These ink compositions are particularly suited to ceramic tile decoration via the double fast firing process, with resulting improvements in absorption, color strength and print definition.

A printing method for printing a printing medium includes a non-white ink application step of applying an aqueous non-white ink composition containing a non-white coloring material onto the printing medium, and a white ink application step of applying an aqueous white ink composition containing a white coloring material onto the non-white ink composition on the printing medium to form a superimposed region. The non-white ink composition and the white ink composition each have an organic solvent content limited to 15% or less relative to the total mass of the corresponding ink composition. The mass ratio of the white ink composition to the non-white ink composition in the superimposed region is 1.5 or more in a portion to which the non-white ink composition is applied in an amount largest in the superimposed region.
