Abstract
An integrated overprint colorful seal with multiple printing surfaces, comprising a seal housing (1), a middle frame (2) accommodated in the seal housing (1), a spring (3) squeezed between the seal housing and the middle frame, a seal body (4) in a regular triangular prism or a quadrangular prism shape, and a driving mechanism. Each side surface of the seal body (4) in the regular triangular prism or quadrangular prism shape is a printing surface (60) in a different color and the printing surface is overprinted on a target object to show a colorful seal pattern. The seal integrates the multiple printing surfaces in an integral whole, can implement semi-automatic overprint of three colors or four colors and is precise in overprint. The seal also supports printing surface replacement and ink-replenishment, and is easy to use and convenient to carry.
