Claim Text:
1. A method for forming a pattern of a print material on a receiver element comprising a receptive surface, the method comprising the following features: (a) providing an elastomeric relief element that comprises a relief pattern comprising (1) an uppermost relief surface, and (2) an average relief image depth of at least 50 μm relative to the uppermost relief surface, (c) applying a printable material composition to the uppermost relief surface of the elastomeric relief element, the printable material composition comprising an electrically conductive print material and a carrier liquid, (d) removing at least 50 weight % of the carrier liquid from the printable material composition that is disposed on the uppermost relief surface of the elastomeric relief element, leaving the electrically conductive print material on the uppermost relief surface, (e) treating the printable material composition on the uppermost relief surface with an acid in vapor or liquid form to form a reacted electrically conductive print material on the uppermost relief surface, and (f) transferring the reacted electrically conductive print material from the uppermost relief surface of the elastomeric relief element to a receptive surface of a receiver element,
