  • Patent number: 4035214
    Abstract: Process for transferring overlayed multiple ink patterns from the surface of a release blanket to a receiving surface on a container or other formed article being printed. A substantially transparent film is first formed on the release blanket, with each ink pattern being printed sequentially over this release film. Proper printing on the release film without picking the release film or previously applied ink films is obtained when certain adhesive and cohesive relationships are maintained between the ink films and the release film. An adhesive film may be formed on the article to be printed, or it may be formed over the ink films and the release film on the release blanket. The receiving surface on the article to be printed is brought into contact with the films on the release blanket, with a resulting total transfer of the films on the blanket to the surface of the article.
