Abstract
The addition of registration marks as an aid in projecting a precision location of a screened artwork or master pattern as used in printing of thick film circuits on a ceramic substrate base is taught by the present invention. The marks are located in a number of locations on the artwork that correspond to a location which will be determined as the edge of the substrate base when the substrate base is printed in proper registration on the artwork to which the registration marks have been added.
