Ink-backed printing ink, also known as flip seal, consists of a cylindrical or square ABS engineering plastic shell, a reversible printing surface under the action of external force, and a color-changing ink pad. Carve the characters and patterns to be printed on the corrosion-resistant rubber pad, and then stick the engraved seal surface on the reversible printing surface plane.

When in use, push the stamp pad into the cylinder, open your palm, point it at the top of the seal, and press it gently. The film with the seal inside will turn over with the power of the palm, and the words or patterns on the printed surface will be pressed on the paper. At this point, as long as the palm pressure is released, the printing surface will return to the fixed printing table and be covered again.

The printing surface of ink-returning ink generally adopts high-strength and corrosion-resistant rubber, which is not easy to deform after long-term use. The back ink seal is equipped with rectangular, circular and square plates and different sizes, which are suitable for factories, institutions, companies and other occasions.
