There are two ways to cover the riding print. The first way is that every page of the contract should have a red seal (front cover and back cover) after the riding seal is covered. The second is that the cover is pressed on the middle seam of the left and right pages (left and right covers). But no matter which one, the purpose is the same, that is, the materials should be stitched together to prevent counterfeiting.

1. When the riding seam stamp is stamped, the materials should ride to all joints, that is, after the riding seam stamp is stamped, every page of the contract should have a red stamp, and the first page and the last page should have words at the same time, not just red circles, and there should be no missing pages in the middle or before and after. The development of contract should be able to restore the riding seal to the original seal. Only in this way can it be a more standardized riding seal and play its role.

2. When there is only one page of material, the riding seal requires "riding seam", that is, the official seal should be evenly covered on the middle seam of two pages of foldable paper, half of which should be kept as a stub and the other half as a voucher. When verifying, the two halves are opposite, and the official seal should be complete.
