Abstract

Certain example embodiments relate to heating a ceramic paint applied to a portion of a coated article in order to at least partially “eat through” the underlying coating, with any remaining materials being removable by washing, and associated articles. In certain example embodiments, the coatings are multilayer sputter-deposited coatings formed on a glass or other substrate. The heat may be provided in connection with conventional heat treatment (e.g., thermal tempering) and/or heat bending processes that otherwise would be performed on the coated article.
