The paste side is gray, so if you paste it on the printed matter and so on, what is under the seal cannot be seen from the back side. These seals are used for changing displayed information such as correcting printed mistakes and correcting and revising catalogues.
As for materials, we have all the kinds of quality paper, art paper, mirror coated paper, matt coated paper and synthetic paper (Yupo) for correction, so we can treat various correcting and revising use such as printing the color and style which suits what you paste seals on.
These seals are in quite a wide variety of use such as displaying food's ingredients and expiration date, displaying material and quality of various products.
Also, we treat a wide variety of printing from simple ones to display a commodity name and caption to printing including a logo or symbol mark. By selecting the material of base paper and ink, we can treat various uses such as heat resistance and cold tolerance.
You can specify logo marks, styles, colors, and so on. Also, you can "clicker cut" the seal base material into the shape you specify, such as a circle or a triangle, without printing.
