A flexographic printing composition which comprises a carrier-swellable particle composition, such as a microgel particle composition, has improved printing performance and printing resolution, especially where the flexographic printing composition is an aqueous printing composition and the carrier is water. The composition is particularly beneficial for flexographic printing of such an aqueous printing ink onto low-energy surface substrates or impermeable substrates, in which the ink has improved adhesion, even in the absence of corona discharge treatment. The use of surfactant in an amount of at least 0.5% by weight of the ink composition enhances printed density and/or reduces mottling in solid printed areas.
