Inkjet printing method

An inkjet printing method, comprising:

• providing an inkjet composition, including:
• a radiation curable monomer or oligomer;
• a photo-initiator;
• and
• an inhibitor present in an amount sufficient to inhibit curing of the radiation curable monomer or oligomer during an initial exposure to a curing energy;
• selecting the curing energy so that it is sufficient to consume some of the inhibitor in printed drops of the inkjet composition;
• printing first drops of the inkjet composition on a substrate in a first printing pass;
• exposing the first drops to the curing energy in a first curing pass and a second curing pass, wherein the first drops retain substantially a same surface tension as a liquid drop of the inkjet composition after the first and second curing passes;
• printing second drops of the inkjet composition adjacent to the first drops in a second printing pass;
• and
• exposing the first and second drops to the curing energy in a third curing pass and a fourth curing pass, wherein the first drops at least partially cure and the second drops retain the same surface tension as the liquid drop of the inkjet composition after the third and fourth curing passes.

An inkjet composition, comprising:

• a radiation curable monomer or oligomer;
• a photo-initiator;
• and
• an inhibitor present in an amount ranging from 0.4 wt % of a total wt % of the inkjet ink to about 1.2 wt % of a total wt % of the inkjet ink to prevent full curing of the radiation curable monomer or oligomer during an initial exposure to a curing energy.
