A thermo-fluid, fast-set ink is disclosed for application to ceramic, metal or plastic ware such as bottles. The ink comprises a solid thermoplastic polyamide resin, formed by interreacting a dicarboxylic acid and a linear diamine, and preferably includes as well a compatible plasticizer for the resin. The resin has a molecular weight and/or is so plasticized as to have a melting point within the range of about 85 DEG C to about 120 DEG C. A sufficient amount of a pigment is present to impart color to the ink. When the ink is to be used on ceramic ware, such as glass containers, the ink preferably includes a substituted organosilane having at least one alkoxy or aryloxy group and at least one organic group compatible with the polyamide resin. The silane serves to bond the resin of the ink chemically to a vitreous surface. The ink is also adapted for a multi-color screening process without leaving screen or pick-off marks. In this embodiment, a succeeding screening application of the polyamide resin involves a different color pigment and is from an alcoholic solution, the alcohol having a boiling point within the range of about 110 DEG C to about 175 DEG C.
