Abstract: Personal memorial plaques which can be used in outdoor, as well as indoor settings, such as in a suitable holder as a marker for the grave of a deceased person or in a niche cut into a gravestone, are described. The plaques are personalized in content and may include any combination of text message, photographs or artwork, or any message, photograph or artwork alone, in any color or color combination, permanently and indelibly imprinted on a substrate such as ceramic tile, metal, translucent glass, natural stone and durable plastic or any other material with sufficient sufficient dimensional stability to be unaffected by exposure to a pressure of 40-80 psi applied evenly across the face thereof and a temperature of about 400° F. for a period between about 50 seconds and about 7.5 minutes depending upon the substrate selected. The process by which they are made is known as “sublimation”.
