2、is specification defines the performance requirements for printed graphic coatings printed directly on resins or other surfaces. It includes printed symbols and inks which have been painted over then subsequently laser etched to become visible. This specification is not applicable to continuous surf

3、ace covered coatings. 2. APPLICATION This specification was released originally to define performance requirements for graphic printings. Typically these graphic printings are applied using pad/tampon or silkscreen printing techniques. The surface on which the printing is applied must also be valida

4、ted using the appropriate Ford Engineering Material Specification. In some cases it will be possible and is recommended to test both the printing and the surrounding surface in the same test, thus fulfilling the test requirements of several specifications (see Table 1).
