1. A method of manufacturing a glass assembly to have an opaque boundary feature, said method comprising:
forming a first glass substrate that is curved, with the first glass substrate having an outer surface (P1) and an opposing inner surface (P2), and a second glass substrate that is curved, with the second glass substrate having an inner surface (P3) and an opposing outer surface (P4);
digitally-applying an organic ink without a mask on at least one of the P2 surface of the first curved glass substrate and the P3 surface of the second curved glass substrate;
curing the organic ink to form the opaque boundary feature on at least one of the P2 surface of the first curved glass substrate and the P3 surface of the second curved glass substrate, wherein the opaque boundary feature has a resolution of greater than 200 dots per inch; and
disposing a polymeric interlayer between the P2 surface of the first glass substrate and the P3 surface of the second glass substrate.
