Abstract
A ceramic ink is transferred to complex ceramic articles by a modified transfer process which allows 20% or greater of the surface area of the ceramic article to be printed. To adhere the ceramic ink to the ceramic articles, the surface of the ceramic article is sprayed with a thin layer of oil. After transfer of the ink design, residual poly vinyl alcohol is washed off of the article while the printed image is held in place by the insoluble precoated oil. The finished ceramic article has a 100% ceramic finish that is very durable.
