Abstract
The present invention is for a method and associated apparatus whereby low viscosity flexograhic printing inks having a viscosity controlling diluent are used in implementing wet trapping of sequentially applied ink layers by controlling the time between ink layer applications such that sufficient diluent evaporates from an applied layer to increase the first applied layer viscosity sufficiently to wet trap a subsequently applied superposed ink layer.
