Method for producing a stamp

Abstract

A method for producing a stamp includes the following steps: (1) forming a stamp member from a rubber material which has a low rebound characteristic and low compressibility; (2) preparing a plurality of stamping inks of different colors, each of the stamping inks having a relatively high viscosity and low flowability; (3) diluting the stamping inks with a diluent to increase their flowability and permeability; (4) placing a plurality of ink-absorbing members in a side-by-side adjacent arrangement and isolating them from one another in order to prevent fluid communication; (5) adding the diluted stamping inks into the ink-absorbing members respectively; (6) saturating the stamp member with a highly volatile liquid; (7) disposing the stamp member on the ink-absorbing members to transfer the diluted stamping inks from the ink-absorbing members to the stamp member so as to have the stamp member formed with regions of different colors, the highly volatile liquid assisting the infiltration of the diluted stamping inks into the stamp member upon vaporizing from the stamp member; and (8) heating the stamp member to remove the diluent present in the diluted stamping inks.
