Abstract

A combination of: a) an inkjet print head having a nozzle density of at least 600 dpi and nozzles with an outer nozzle diameter D smaller than 25μm; and b) a UV curable inkjet composition containing 0 to 10 wt % of one or more monofunctional monomers and at least A wt % of 2-(2-vinyloxyethoxy)ethyl acrylate, wherein both wt % are based on the total weight of the UV curable inkjet composition; and wherein A is defined by the formula 100 wt %−D×3.0 wt %/μm≦A≦100 wt %−D×1.0 wt %/μm.
