Abstract
A printing process prints a continuously moving substrate with elongate, semi-tone graphics. The printed substrate is incorporated into a composite elastic material, in which the substrate is contracted, thereby forming a desired full-tone graphic from the semi-tone graphic.
Claims10
A process for providing a printed elasticized substrate, comprising the steps of:
- continuously moving a substrate having a printing surface,
- printing a semi-tone graphic with an amount of ink less than the amount of ink for a full-tone graphic on the printing surface of the substrate,
- elasticizing the substrate after it has been printed, and
- contracting the substrate to provide the full-tone graphic.
