The invention discloses a matte printing ink composition for a PCB (Printed Circuit Board) as well as a preparation method and application of the matte printing ink composition. The ink comprises the following raw materials: epoxy resin; matt resin; a photoinitiator; a photosensitizer; a filler; wherein the matt resin is prepared from at least one of the following components: Dexaxyid 250N, Dexaxyid 350N, Zhahe TQ100, Zhahe TQ100 and Zhahe TQ100. According to the invention, the matte powder is not added and is replaced by the matte resin, so that the glossiness of the board surface of the circuit board is reduced, and the matte effect is realized. According to the present invention, the matte resin is adopted to replace the matte powder, such that the environmental pollution and the influence on the production process by the matte powder are avoided, the production efficiency is improved, in addition, the adhesion and the optical performance of the matte resin are good, and the matte resin comprising at least
