A homogeneous ink for use in postage meter inking systems. The homogeneous ink is formulated by dissolving a coloring material composed of fluorescent toner in a non-volatile solution blend consisting of low molecular weight, low viscosity, non ionic surfactants with alcohol or ester terminal groups having an HLB number varying from 8 to 15 and glycols. viscosity modifiers can be used as thinners and thickeners. A surface tension modifier compatible to the system of the polyether-alkl/polymethyl- siloxane copolymers type can be added in trace concentra- tions. The ink components of this invention are all hazard free, non-hygroscopic and do not adversely affect the materials of the inking system in which they are used.
