A pattern of an electrically conductive print material is formed on a receiver element using an elastomeric relief element that has 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. A printable material composition is applied to the uppermost relief surface, which printable material composition contains an electrically conductive print material and a carrier liquid. At least 50 weight % of the carrier liquid is removed from the uppermost relief surface, leaving the electrically conductive print material on the uppermost relief surface. Either the elastomeric relief element or the printable material composition on the elastomeric relief element, or both, are treated with an acid in vapor or liquid form to improve conductivity of the electrically conductive print material after it has been transferred from the uppermost relief surface to the receiver element. |

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,
carrying out at least one feature (e), andrepeating features (c) and (d), in the noted sequence, at least once using additional amounts of the same printable material composition and the same elastomeric relief element, to provide an increased amount of electrically conductive print material disposed on the uppermost relief surface. |
