Abstract
Methods for digitally printing on various articles, particularly ceramic articles, are disclosed. A first step includes applying a fluid glazing material to an article creating a coated surface. The fluid glazing material can either contain an underprinting agent for accepting and adhering chromophores to the fluid glazing material, or the underprinting agent can be jetted onto the fluid glazing material prior to the jetting of chromophores onto the article. A chromophore-containing fluid is then jetted onto the ceramic article and the article is fired. Additionally, an inkjettable composition is disclosed having a large amount of metal ion present in the composition.
