Abstract
An inkjet printing method includes providing an inkjet composition, which includes a radiation curable monomer or oligomer, a photo-initiator, and an inhibitor present in an amount sufficient to prevent full curing of the radiation curable monomer or oligomer during an initial exposure to a curing energy. First drops of the inkjet composition are deposited onto a substrate. The curing energy is selected such that it is sufficient to substantially consume the inhibitor. The first drops are exposed to the curing energy, whereby the first drops retain substantially a same surface tension as a liquid drop of the inkjet composition. Second drops of the inkjet composition are deposited adjacent to the first drops. The first and second drops are exposed to the curing energy, whereby the first drops are at least partially cured and the second drops retain substantially the same surface tension as a liquid drop of the inkjet composition.
