A method for decorating and/or labelling glas articles and like ceramic ware by screen printing. The present method comprises the steps of: (a) treating a glass article or the like with a silane adhesion promoter; and (b) applying a non-ceramic screen ink directly onto the silane-treated glass article by screen printing. The non-ceramic screen ink is preferably a heat-set ink which includes an organic resinous binder, a non-heavy metal colorant and a vaporizable solvent system. Examples of the binder include, but are not limited to, one or more of polyamide, polyester, polyester-vinyl, acrylic, vinyl and acrylic-vinyl resins. Examples of the non-heavy metal colorant include titanium dioxide and organic colorants (e.g., insoluble derivatives of organic dyes). The non-ceramic screen ink may additionally comprise one or more rheology-adjusting agents for making the ink well-suited for screen printing and may additionally include other additives of the type commonly found in screen or other printing inks. Once the ink has been applied to the glass article by screen printing, the printed article is preferably heated, causing the solvent system to be driven off and causing the binder, colorant and other non-volatile components of the ink to be set on the article.
